what mods were done to the tranaxle to hold all that power down? as i understand the standard turbo axles can only withhold 600hp before damage is done, your work is amazing by the way, i love it when the banners fly off! lol!
@anoldmanc California Motorsports built it (google them), steel & billet parts throughout, not sure on the particular mods. We broke the standard Ultima axles/stub-shafts with 500hp, we have an 'unbreakable' set that is proven to over 1000hp.
@FT86TT Since most Ultima's have different HP engines from eachother, its hard to say. A lower powered one could hit as "slow" as a 12-sec 1/4 mile. Since Ultima's are set up for road racing, their suspension design & stiffness isn't great for drag racing.
ET (elapsed time, or seconds) is relative to traction.
Speed is relative to horsepower.
If you look at my other vids, you'll see that this Ultima went 145 in the 1/4 mile. A drag car (with good traction) would hit 8's for sure w/that HP.
@leloodallasmultipass there is something about the clutch engagement (being a high performance clutch and all) that makes it tough for the driver to smoothly let out the clutch into first gear.
@DaleTail do you need to use first on the dyno? I am a little unfamiliar with the process. I had a porsche 914 with a chevy small block in it and I usually just skipped first but that was for driving around town, not testing the power.
@leloodallasmultipass Yeah, 1st gear is geared for close to 60mph at redline. The car is light but the clutch is pretty 'grabby' so it would be hard on the entire drivetrain especially the clutch.
@madman8718 The issue ended up being the size of the master cylinder. Swapped it out (sorry, but i dont remember the sizes) for a different size and it's way easier to drive since this vid was shot.
Awesome Ultima GTR. I bet this thing hauls ass. With over 800 hp and massive torque, it amazes me that people can nit pick torque vs hp on this thing. I'd like to see any but the most expensive production vehicles even give this a run for its money.
Nice job mate. I think the Ultima is one of the best kits, light weight and big engine combo is the way to go. I would love to see this thing against a Porsche or Ferrari, this thing would make them look stupid lol. And fraction of the cost I'm guessing.
turn up the boost a little aand the ferarris will destroy this midievel pushrod clunker.
and to think, just two decades ago some bright folks were getting twice this much power out of 1.5 liters in the golden age of formula 1.
i would have at least bumped up the compression some if i was only planning to make 15lbs of boost...at that level he could pull off 10-11:1 depending on fuel, and i can guess that its below 10:1.
And I know 20-30lbs can be used safely. During the F1 era they pushed 40lbs and more. Some didnt bother using a waste gate to control boost. So I was replying to your F1 comment. An F1 setup has no real place for a street car. You mentioned dohc 4.2ltr with 20-30lbs, this make more sense, would be more drivable and street friendly and reliable. And yes I love Cadillacs but completely different reasons. I think a tried and tested Ls7 is a good way to go also.
F1 cars made 75-85lbs of boost, and if you think there were non-wastegated motors at this level you're insane.
these f1 engines lasted entire races at 50-60lbs of boost with no probem. they swapped out a different motor because thats a very good insurance policy, but the reality is that i HAVE SEEN A USED QUALIFYING ENGINE TORN DOWN AFTER OVER 8 HOURS OF RUN TIME, MORE THAN HALF AT FULL BOOST, AND I COULD STILL SEE THE CROSSHATCHING IN THE CYLINDER WALLS, AND THE BEARINGS WERE PERFECT
by the way, im not sure why you are acting like you know about the inticacies of performance with me. i know virtually EVERYTHING about internal combustion engine performance
you obviously think theres also some middle ground where having a car that doesnt perform to its full potential is good for something other than wasting money and getting beat.
there are 20-year old turbocars built for 1/10th the price of this, make more power from less motor and actually have class.
Im not acting like anything; I have done some work on cars my self.
The F1 engines are a bad example since big dollars of development was needed to get them there. Is all I was saying, this ultima is basically using big cubes as a substitute for big dollars on a smaller turbo motor. At the end of the day it depends what a person wants out of a car.
This comment has received too many negative votesshow
@toranacar BECAUSE THE 4G63 AND ITS PARTS ARE LESS THAN HALF THE SIZE OF THE LS2'S, AND MORE EFFICIENT, THE ONLY SPECIFIC PARTS THAT WILL BE MORE EXPENSIVE THAN ITS LS2 COUNTERPART WILL BE THE TURBO CHARGER AND FUEL INJECTOR(S)
OH WAIT YOU ONLY NEED HALF AS MANY OF EVERYTHING!!!
you dont know shit. i looked at you channel and you have a fucking ford ranger. go get a car thats worth talking about. then you wont look like an idiot.
type in 2100hp turbo dyno session ... and see a PUSH ROD v8 with a CARB MAKE BIG POWER ..he even said the turbos are way to small ...look evan a 2000 hp supra still has that 6 cyl sound AAAAAOWW now on the otherhand a big block v 8 sounds like a massive beast from hell..look man the performance experance is the look the power and the SOUND!!! why short change your self.572PUSHROD2valve per cyl vs small DOHC v8 there never over 5.7L both 30lbs boost . the 572 wins hands down
You know your car is the fucking shit when you blow shit off the wall at WOT!
Fuck what a beast! But jesus that guy driving needs to find a new job! I realize the clutch is probly a stiff as shit race clutch but I'v never seen a car buck that damn hard on a dyno! Much less three times in a row! If I was the owner of the car i'd yank his ass out of there pronto!
The owner was the one driving. He is an excellent racecar driver, he knows what he's doing. Sorry you haven't seen a car buck like that before. Its touchy, ive driven it too.
Modified porsche transaxle is somewhere around $11k i believe, including clutch/axles.. engine setup and custom turbo system would probably cost $35k+ w/labor...
hard to put a number on it since labor wasn't an issue, he's the owner of Schwartz Performance; can't really bill yourself on labor :P
No matter how many times I watch this, when he hammers the throttle at 0:53 seconds in, the hair on my spine stands straight up every time! Actually Dale, can you answer me a question or two please. After seeing the in-car vid of Jeff doing the 0-200-0 run, I was left wondering why the shifts between gears seem to be so quick. Also, this thing is geared high for 200+ mph, but since the transaxle was rebuilt anyway, why didn't he have a lower first gear put in it to give it a better launch?
the shifts between gears werent that quick, he shifted at 6500 or so pretty much every time. 1st gear goes to 62 mph if im not mistaken, so it is pretty low anyways. My 5 speed miata 1st gear is at like 30 lol.
In almost any TT car that weighs next to nothing with road racing suspension (vs drag), 1st gear is usually useless. Even in non turbo cars, if there is a lot of torque it'll break 'em loose. If you saw the drag strip runs, he spun until 4th gear anyway.
You say that LS engines don't like boost, but the LS9 seems to do just fine. I'd wager that you could get 1,000 horsepower out of it quite easily if you swapped the power-robbing supercharger for a sequential turbo setup.
you can get 1000 hp out of ls2's and ls7's easily too like Jeff did. The LS9 was made for boost, I wasn't talking about that. LSx's have 4 bolts around each cylinder making the heads prone to lifting at or over 20psi. The LS9's have 12mm head bolts i believe instead of 11mm which is a big help.
I must say I'm curious as to the nature of the gearbox. If I'm not mistaken, the Porsche G50 unit specified by Ultima was meant for a car with less than 300HP of output - are you using a modified gearbox, or have you swapped it for something beefier?
you are correct, its a g50/52 transaxle. PowerhausII / california motorsports upgraded the transaxle with a lot of billet internals etc. Ultima's stub axles and axle shafts dont hold up to 500hp (Jeff broke one of each at different times) so he has custom ones made specifically for Ultimas that are guaranteed unbreakable.
I find it funny that you say that, as Ultima claims that you can put a 1,000 horsepower engine in the car without snapping the axles.
Presuming 1,000 horsepower can be produced from an LS2, I wonder how much could be made from a turbo LS9? The Ultima seems to cope remarkably well with such absurd power, so why not see how far you can go? I'd bet you could squash the Veyron's 0-200mph time and set some nurburgring records.
(As you may have guessed, I'm a big Ultima fan. Men in sheds FTW!)
Yeah, maybe they upgraded the axles since 2003 but i dont know. We may be doing a twin turbo LS9 in the very near future for jeff's 81 turbo trans am. The ultima doesnt cope well with 1000 hp, it doesnt hook up until 3rd or 4th gear. Jeff's 0-200 was 23 sec, not sure what the veyron was. Check my other vids if you havent already.
It looks like allot more than that! it looks like it wants to torque the bench. I would check the calibration on the bench re-chain the GTR better and retest. that number just sounds way too low for a twin turbo unless it is on a SB287.
Revs sound good, looks like the driver needs to work on that clutch release though.
Don't know how it's low for a twin turbo when they all make different horsepower numbers, andddd the clutch is a fully metallic racing clutch with about 2 inches of travel so its not easy lettin it out smooth.
822hp sounds impressive on it's own, but that's only 100hp more than a stock GTR720 that runs a normally aspirated small block with a carby. Reasonable boost (i.e. only 7 psi) on a 6 Lt small block with twin turbos should pretty easily exceed 1000hp
the clutch is a full metallic disc, and it is like a light switch as far as engagement goes. It is pretty tough to get rolling into 1st gear. Basically its a racecar clutch.
Then I'd look into a Tilton triple or Quad disk. They regularly handle 1000-1400whp on big single turbo Toyota Supras and slip and drive very very close to stock. Also another thing I noticed: Why does it sound like this car is being dyno'd in 3rd gear? Were the numbers corrected down for the non-1:1 ratio?
Yeah, it is dynoed in 3rd. The corrected numbers were actually higher than what this video says. Corrected was 826hp. The last run was done in 4th gear, but it didnt run right for whatever reason so he let off early.
Beautiful! I talked to your dad online a few times on the MTS cadillac forum a few years back when I started my cheap caddy powered project, his caddy was sweet but this this thing defies description!

Why would you want to do that, to make less power? oh, thats right, you probably like the noise.. and mustangs..

what wheels are you guys runnin on this car, or are they stock?
stauff09 3 years ago
they are 'stock' ultima wheels, made by OZ Racing. 18" by 13 in the rear.. 8.5-9.5 i think in the front

822hp sounds impressive on it's own, but that's only 100hp more than a stock GTR720 that runs a normally aspirated small block with a carby. Reasonable boost (i.e. only 7 psi) on a 6 Lt small block with twin turbos should pretty easily exceed 1000hp

the ultima gtr720 is 720 at the crank not the wheels. at the wheels its probably around 550-600. the 720 is also larger than the ls2.
At the crank, this Ultima is right at 1000hp.

That's a fair enough explanation. Thanks.

This car continues a grand tradition of British sports cars with American engines.
As a side note, one of the best ways to check the experience level of a foriegn-car mechanic is to say "British Leyland" and see how much he cringes.

why does it look like the car is stalling on some parts...it jerks violently

the clutch is a full metallic disc, and it is like a light switch as far as engagement goes. It is pretty tough to get rolling into 1st gear. Basically its a racecar clutch.

so thats 822 at the wheel?
That thing is awesome, how much does it cost to build a similar set-up? =)

Then I'd look into a Tilton triple or Quad disk. They regularly handle 1000-1400whp on big single turbo Toyota Supras and slip and drive very very close to stock. Also another thing I noticed: Why does it sound like this car is being dyno'd in 3rd gear? Were the numbers corrected down for the non-1:1 ratio?
6spdSC4 4 years ago
Thanks.
Yeah, it is dynoed in 3rd. The corrected numbers were actually higher than what this video says. Corrected was 826hp. The last run was done in 4th gear, but it didnt run right for whatever reason so he let off early.

Nice to see an American using an Ultima GTR.

Well, we at least get to own them if they're powered by Corvette engines! :D
It's pretty much my dream car.

Beautiful car, how much do you think it would produce with a supercharger @ 10-12 psi?
gumby83 4 years ago
pretty hard to fit a supercharger in there.. but with that exact engine setup with just a sc it would be right around 700 rwhp. maybe a bit more.
DaleTail 4 years ago
You can get a SC as part of the pack for an Ultima. You can pretty much get any V8 and use any type of forced induction you see fit.
Near where i live in the UK some one has a 5.2L TT setup, don't know how much power though.
