Unrestricted road race Corvette gets some engine updates for 2009 - chassis dyno

[bm717252]

How come the sound of that LS7 is different from all the other modded LS7's. this one has a higher pitch. What kind clutch and flywheel combo do you have?

[KatechPerformance]

@bm717252

Tilton triple plate carbon

[islumbum]

Could you convert a Stock C5 Coupe into a C5R, and still be street legal? Basically I'm asking can you turn a C5 Coupe into a street legal C5R? Including weight reductions.

[dreamer6064]

that dash is bad

[ssadriank]

FUCK

[isaiah213]

Wicked vette ant i would love a transmission like that in a corvette or any chevy

[NickNugget1978]

Katech, you may think this is strange, but I live right down Jefferson from you, and every once and a while, late at night, I'll drive by and dream. =] (Creepy, I know.) You guys rock. My Dad works for Les Stanford Chevy and every once and a while I go up there to have lunch with him. Before it was sold, I loved to see ClubSport, that thing is just mean! I hope one day I'll be bringing something to you! Keep up the good work, and let me know if you need someone to sweep floors!

[KatechPerformance]

@NickNugget1978

Stalker...

Just kidding. We love your enthusiasm.

[urbandestruction]

@KatechPerformance kinda hard to have a car like this and not have stalkers lol. why cant i ever see one of these here in victoria, british columbia canada.

[9babablacksheep]

Is this Car set up like the gt1 gt2 or gt3 race car? and if its not set up like those cars how much power is it making?

[KatechPerformance]

@9babablacksheep

It's closest to GT1, but in some ways beyond that because it is not built to a set of rules. The engine made 650bhp.

[urbandestruction]

trans. what kind? whats the drive train specs other then the engine. please and thanks :) wicked car, the owners one lucky person.

[KatechPerformance]

@urbandestruction

Holinger SMG

[urbandestruction]

@KatechPerformance thanks!

[jeffzahnd]

so what is the main purpose of this car? that is besides scaring women and children? what type of tracks use? where ya racing it at?

[KatechPerformance]

@jeffzahnd

The car scares some men too. It's used mostly at Autobahn Country Club circuit as a track toy and demonstration vehicle.

[jeffzahnd]

@KatechPerformance Well if you need a project car, I have a c5 you can use anytime! :P

[turbojunkie006]

Id drive this bitch on the streets!

[MGTech30]

Boy oh boy! Love that sound.

[Munroman]

Little known is that Peter Holinger was Jack Brabham's transmission manufacturer in the 60's when he operated out of his house

.

Brabham + Holinger + Ralt = back shed F1 World Champions

[KevinSaale]

Listen to it fucking shift, unbelievable

[SEMAChannel]

Nice vid, thanks for sharing. Please keep 'em coming.

[shaggyjman]

oh my fuck!

i love you for this.

[SinisterC6]

i got to see this car today in person while at fall-line, amazing

[HammerE30]

I love how it's deep rumble turns to a high pitched scream

[bulldog32220]

GOD id love to take that mf'er for a spin

[KatechPerformance]

@bulldog32220

I have and it's absolutely thrilling. The sequential manual gearbox is the most fun part. Wide open throttle no lift upshifts.

[3L3CTR0static]

Damn I don't like v8's at all but this thing is beaaaaaaaaaaaaaaaasssssssstttt­ttttt!!!!!!!!

[tuugfo]

@3L3CTR0static what person doesnt like v8's thats like saying i dont like pussy

[MangoSmoothie16]

thats a semi auto isnt it?

[KatechPerformance]

@MangoSmoothie16

No, it's a sequential manual gearbox.

[1Vette2nv1]

@KatechPerformance hi, what does that mean?

[KatechPerformance]

@1Vette2nv1

It means it's a manual gearbox that goes through the gears sequentially. Not an H-pattern, but pull back on the stick up through the gears, forward to go down through the gears in sequence. This car has the engine management system cut the power momentarily between upshifts so you can up shift with no clutch and without lifting off the throttle. It's exhilarating.

[91cannibal]

@KatechPerformance where can i get one of these transmissions and how much?!?!?!!!!! lol

[KatechPerformance]

@91cannibal

$30k from Holinger

[miamiforlyfe]

could i put that same engine in my 94 Z28 camaro? and what is that engine? what block, what heads, what cam? please.

thanks!!

[KatechPerformance]

@miamiforlyfe

It's possible. LS7 block, LS7 heads, GM Stage 3 cam.

[miamiforlyfe]

@KatechPerformance So how do you get it to sounds like that? high rpm, shifting real fast? its like an american muscle F1 car.

Thanks for the feedback :)

[KatechPerformance]

@miamiforlyfe

Holinger sequential gearbox

[miamiforlyfe]

@KatechPerformance Is that possible to put in a street legal car?

[gforce91]

@miamiforlyfe its just a high rpm cam this thing revs up to 8,000rpm+

[Revazconceptx]

YEah how much cost this motor katech ?

[PwrdbyLS1]

How much cost aprox. these Holinger sequential transmission? Sick car!

[KatechPerformance]

@PwrdbyLS1

$30,000

[ylism]

Sweet sounding motor. V8 just sound great at speed.

[MickCollinsb16b]

what a monster!!

[n9athan]

how much does this monster cost?

[mynewgroove]

UN-FUCKING-BELIEVABLE!! That might be the best noise in the world...

[fasttzr96]

Very beautiful sound!!!! nice change!! =)

[41sanziman]

This porno im going to jerk know

[porkpig350]

speechless...best porn ever!!! long live!!!

[darryleshelly]

Look at that ground ? with those RPM's . LOL

[dckmn52]

ill gladly trade a T56 for that transmission :P

[86AMac]

sik!

[sirlonghair]

wannt one without the wing stock black and a slightly more streetable twin turbo that tranny stays add a GPS and you won't see me on sundays

[darryleshelly]

That is SICK !

[LaughedoutLoud01]

WOW

[2muchrightft]

What a beast, great job! Is this engine what we would have seen in gt1 w/o restrictors or is it too high strung to run 24 hours?

[KatechPerformance]

It is not the same engine. The one in the video is a production-based LS7.

[kcarrab]

its sh!t like that, that makes life worth living!!! very nice.

[est19791]

what was the final hp after "improvements"??

i love the sound of a tight v8 with goor exhaust work.

[KatechPerformance]

650

[jessejames760]

what type of tranny is that?

[KatechPerformance]

Holinger sequential

[71getitdone]

The skull on the pillar is befitting for this car , I love that shifter ....

[antipeacemilitias]

now imagine the engine, transmission, rear end, suspension etc in a phili motorsport chassis C3 corvette 'pure evil'

what are you guys running in that block?

[1pinchipendejo]

That must be the fastest car in the world without a steering wheel lol!

[jrranda]

kan't beat a katech! what is redline set at?

[KatechPerformance]

7000

[zman6033]

ya should take this to those big Time Attack races at buttonwillow and inter in the unlimited class should make all those imports look like shit there like the Time Attack Cobalt SS did a few years ago

[gmaxking15]

SWEET....im in love with that shifter

[ybdiffrent]

OK, I will hazard a guess. The numbers are 720HP with about 680 lb/ft of torque. :-P

[KatechPerformance]

More like 650hp/570tq

[ybdiffrent]

Well, that works, too! just bustin your chops. GREAT JOB!! Katech is the premier performance shop!! Bar none. Cheers.

[ybdiffrent]

I love the sand-bagging. Numbers are hidden. The sound is all you need.

Classic. :-)

[dvandentop]

I have ridden in this car on the track it is as BADASS as the video makes it out to be!

[backupboy777]

sweet ride dude awesome look

[ridethedurt]

& GM is going bankrupt. What a Crock Of Shit. That is because they R jealous of the American Way. What Pussys...

[VetteAholicZ06]

SHIIIIT, that engine sound! My snake has left the cage in search for love!

[leoalero]

ow can it rev and shift on the ground???and whats the RPM??

[SinisterC6]

its on a dyno, the rear wheels are spinning two huge drums simulating the ground

[leoalero]

ohh,i didnt see it!!Thanks!

[deadfaithful]

fuckin awesome

*favorited*

[ElementOfC]

What's the update rate on that ADL2's tachometer? Looks like it's higher than 30hz, which looks nice and responsive.

[NemSSCamaro]

how big is the lift on that cam? it has to be higher than .700

[KatechPerformance]

.630

[NemSSCamaro]

thats insane that your cams are so small but make such incredible numbers!. i dont understand it.

[zman6033]

becouse these guys are wizards when it comes to those engines it doesnt have to make sence LOL

[DJ2H]

damn I fell in love, that is so bad ass.

[DuenkelPortraitArt]

OK, my son sent me this link... Uh, you guys need to geta grip if you think a dyno test makes good video!

:)

(But it's GREAT if I turn off the video and just LISTEN!)

[ldmcnutt]

I wish my c6 Z51 sounded like that. That is sooo sweet.

[ridethedurt]

An American Revolution...Balls On Fire.

Dodge,Ford,Import KILLER...

[Nodsldmc007]

very crazy dyno session! Looks like that 3rd gear goes on forever and then 4-5-6 go through really fast. What did it put down?

[KatechPerformance]

The car has to start out in 3rd gear because there is so much torque and power there would be rubber all over the wall and rear of the car starting out in 1st or 2nd gear. 3rd gear is not that tall of a gear and does not go on forever and is rarely at such low RPM.

[Isaacbolly]

What type of gauge cluster is that?

[KatechPerformance]

Motec

[atlram1]

Simply amazing! I'm hoping to see this monster in-person one day.

[Petrolhead1984]

This the baddest road race vette i have ever seen

[dvandentop]

bad ass car mike cant wait to see at track attack

[Petrolhead1984]

What did it make ?

At the wheels?

[KatechPerformance]

They are still working on it, we just wanted to get this video up ASAP. I can tell you it made 650hp/575tq on the engine dyno.

[triplexxxsatyr]

Fuckers...I'm so fucking horny right now.

So what...does this mean this will be the setup for ALMS this season?

[KatechPerformance]

No, this is a privately built car that does not meet ALMS rules. Its more of a track toy and not for competition.

[triplexxxsatyr]

I getcha. Thanks for responding! I will be cheering on Corvette Racing in GT1 ALMS Racing as I always have for the last five years. And now that I see Corvette Racing will in GT2 also, well, I see no reason not to be optimistic this year.

[saygmo]

What transmission? electronic controlled sequential of some sort...? That thing sounds freakin awesome, but I love the no lift shifts and downshift blips as well!

[Svensson81]

I've got a question regarding that.. Check his right knee during upshifts, you can see he's still lifting the throttle a little bit. Is that because there's no ignition cut-off or simply just to smoothen the upshifts a little bit?

[KatechPerformance]

I don't see what you're talking about. I see his leg shake a little bit on the shift, but I assure you, its wide open throttle the whole time.

[KatechPerformance]

Holinger sequential with a Holinger shifter. The shifter has a microswitch in the handle that senses the shift and tells the Motec engine management system to momentarily cut ignition.

[Svensson81]

Thanks for the info, that's what I meant. Must have been seeing things that weren't there =]

[mannyzx]

DAMN!!! now thats efing epic right there!

I would hate seing this beast behind me thats for sure, street or track, good job man just wow!!!
