[alliancefreak]

REV IT NOW REV IT NOW WHILE HES NEAR IT ...BOOOOOF AHH IM ON FIRE LMFAO nub

[hakosuka2]

all fun and games until you check the fuel bill!

[12valvepower1]

@hakosuka2 that is what kept me out of wankels.

[aaroncake]

Running a bit rich there at idle? Sounds like a big bridge.

[TomaSpeed]

It's an original European 12A engine, with modifyed original carb.

[plav032]

What? Do even know anything about rotary's? If its not shooting flames, it ain't happy. BRAP BRAP BRAP BRAP, love that car, what kinda port does it have?

[plav032]

Relax pal, no need to be a dick because you feel your tastes are superior. I respect your taste in cars, I would have loved to been around in that era when R100s were not like finding a needle in a hay stack. But to me this "faggoty blue-purple monstrosity" doesn't look like a half bad way to have some fun on the track. Obviously this car wasn't built with style, n show in mind, its a track beater, that was slapped together in mind that it would be abused, and was likely spray bombed this blue.

[exonerator]

:C you gonna give me ugly rx-7 nightmares

please, dont ever mod this beauty into a drag >_>

[12valvepower1]

bis du kalt? ahahahha

[ducatiracing]

lol come to australia, most people use rotaries for drag racing here

[Maalevolent]

that its not a car! is a motor whit weels :D

[jdarens]

OK it's not a waste of gas... any rotary without a cat will shoot flames. They run super rich because they don't get a complete burn.

[TomaSpeed]

Or is it because we modified a little bit too much the carb ...? :)

[Colarx8]

to much gas

[Ilxfauno]

might want to thin it out a bit but I think it's fine, a bit leaner might give ya a better burn and slight gain in hp. experiment mate

[terryrouge]

@TomaSpeed I know it doesnt matter but, mpg? haha

[125crg]

@jdarens stfu

[TheLagartijamovil]

@jdarens if you don't know what a fuck have the motor don't talk shit

[ducatiracing]

@jdarens mine doesnt run a cat and that doesnt even blow smoke so i dont know where your getting your info

[coboisarapatanas]

is it a flamethrower :)?

[superdude361]

its dorta a waste of gas because your not burning all your fuel so your loosing money and power

[TomaSpeed]

A little bit more fuel a low RPM is good for cooling the engine !

[SiMoNsKy22]

i'd rather loose a tiny bit of power than see it melt? and yes it does aid cooling the engine...very slightly depends on your intake system

[superdude361]

that is true but at what cost to your exhaust pipes? if they get hot and warp you wont get the right flow which will overall drain your horses slightly

[SiMoNsKy22]

ok and how hot do u really think ur exhaust is gona get? when have u ever seen an exhaust manifold warp? i havnt and certainly aint seen anyone elses warp...flames wont warp your exhaust...not sooty yellow flames but blue flames will

[superdude361]

sorry thats my bad lol mine warped because i use straight nitrous when i race thats probrably why i was confused.

Rotary my ati piston

[SiMoNsKy22]

drag car? u wud need a tank the size of a tanker full of nos to race round a track?!?!?

[superdude361]

not totally nos just to start and finish the race with

[blyndrotor]

Easy, set up the Nos to fire for a set period of time when full throtle is hit. Say, a 5-10 second burst.

[SiMoNsKy22]

yeah just like the turbo's in formula palmer audi....only get a set ammount of boost per race

[superdude361]

its dorta a waste of gas because your not burning all your fuel so your loosing money and power

[killer84stang]

Naw... its a rotary thing... they do that when you run them off with good fuel too... my 1.3L hasn't held one that long, but if i got down the highway I get a steady flame...

[brookeyey]

dat must have a lot of power to keep the fire cumin out like that lol

[RotaryKid84]

wow my 7 spits flames to urs is non stop why.And what kind of port is that also how much hp does a beast like that have.But nice first gen man that shit is sick.

[TomaSpeed]

About the engine:

Sorry, but I can't say anything about the engines porting or its hp.

I purchased the engine as new some 18 years ago from a Mazda dealer in Luxembourg (Europe), who imported it directly from Japan (he said), so that I think it should be an original one.

But compared to my other RX7s, it the best engine that I ever had ....

[TomaSpeed]

About the flames:

1) After 2 hours of non-stop racing, the exhaust system was extremely hot.

2) Due to my self-modified Niki carb, the car runs a little bit rich at idle.

3) We tested fuel/synthetic 2t-oil mixture 100:1 without OMP for the first time.

4) We run a very big self-made straight trough exhaust system.

So if you put 1), 2), 3) and 4) together you'll find the reason :-)

[TomaSpeed]

We didn't care too much why this happened, because we planned some major changes for the next season:

A Bridge Port engine

Weber 48 IDA carb

Self made 4 coils DFI System

Change the fuel/oil mixture ratio

......

[mrwankel82]

That sounds crazy awesome! sweet...
