STIs are not "Red Light Racers" even though they can do it! If you see what they race on in WRC they aren't doing a whole bunch of driving on straight roads. Swap the STI for a Camaro then you have a straight line performer!

I have hung with a Mustang GT. I had a thread but it was closed b/c I didn't know you can't post street racing on here. My apologies to the Mods. Do a search and you will find it. I drag raced cars and bikes so either he was a bad driver or my 8 was on yesterday.

I had a thread closed by IKE simply because I made a comment about staying neck and neck with a Mustang GT (99-2000ish?), not the new ones....I always laugh when guys come here saying the 8 is slow compared to other sports cars? 6secs is not slow, but it is not fast either. I don't consider the car fast, but look at the group itself, WRX (not STI), RSX-S, even BMW330....etc etc...the 8 is as fast or quicker than those cars....but lets call it a drivers race...even the G35C....I don't think it is all that much faster, and I have had real world experience with that one, but I won't talk about it here

Hornet,

I run my greddy kit at 14 psi of boost and a stand alone ECU for 3-4 moths without any problem...........we believe that this car's can handle 14-16 psi without any problem........
My friend run's his car at 19 psi of boost without problem..............
Run high boost don't means that we're goin to break the engine in two pieces, tuning is the key.
anyone can brake and engine with just 5-7 psi of boost, all depends on tuning.

Manuel

jwbond

manuel, what kind of rwhp are you putting down with that kind of boost?

if i recall you also put on larger injectors?

Hornet

I apologize Manuel, I have a lot of respect for what you have accomplished so far! I didn't know you had turned the boost up, I did remember you were first to run 273whp in PR but I thought that was not with the boost as high as 14 psi. What kind of numbers do you have on the dyno now? How much is your friend with the 19 psi making on his as well?

RX8PR

Hornet,

you just have some confusion,

I maked 273 HP and 235 lb of torque with the greddy kit at 5-7 psi of boost and tuning.

Then we use the greddy turbo but with and upgrade in the fuel system, stand alone ECU, etc, and maked 305HP at 16 psi on high boost. I keep the car 3-4 months runing at 14 psi on low boost without problem.
On that time I was thinking to get something near 330HP, but we found that we need a turbine that can supply more cfm than the greddy turbine.

I saled my greddy kit a month ago............................

Now we're installing a GT3540R and a spearco intercooler, we're installing the turbine in the front of the car and the manifold is killing us, it's taking to much time, but the guy that is making it tell me that he is goin to finish it this week.

My friends car maked 392HP at 19 psi of boost.....................but to run lower boost he decide to port the engine and now he is making 374HP at 14 psi of boost.

I remember months a go that we was thinking that it was cheaper to install
and old 13B engine on our cars to put the cars on the 350-400 HP range, but we decide that the fun and the respect came if we work with the RENESIS engine.

omg. that makes me really happy but can anyone in the states yield these results for our cars? ROAD TRIP TO PR!!!! can we drive there? LOL

more specific on the porting pleaseeeeee

Moostafa29

You must have the "special" issue RX-8 if you plan on driving there :p

kw1k

yea, i have to say our 8s are quick, but their not that fast, If the 8 had more mid / high end then wat it has it would be much more fun to drive

RX8PR

Our car's use ball bearing turbos and they turne the boost fast..............

If any one is interested on my car, I can sale it!
The problem is that in PR we payed higher taxes than in the US..................

Manuel

Yes, the respect will come from the Renesis.

Wait until I tell my local tuner, Lopez, what you are doing. He is from PR and loves to hear these stories.

Good Luck :D

I thought that everything from the tranny to the steering wheel would fall off as soon as this car reached 300whp.

What other mods has the guy done to support 374hps?

/twospoons

Hornet

Those are amazing numbers! It's very good to hear that those numbers are possible. You and your friend should come tune in the US. Nobody here has seemed to be able to do those numbers (or they don't seem to come to this forum). I'm sure you made lot's of members feel better about buying the 8 because of the numbers. Now people know with hard work the car can do very good numbers.

Red Devil

Manuel, on the car that is around 375hp, is that one running the stock transmission, driveshaft, etc...? I assume it must be taking some serious abuse.

RX8PR

No one's know how much power the stocks parts can handle................we would run some stock parts until we broke them.........................it's part joking but sometimes is serious.

To make high HP you need good mechanics, seriously the best rotary ones are in the Island. The secret it's to have complete control of the engine with a stand alone ECU.
I'm using the stock ECU to control the gauges, power steering, air conditioning, etc.
and stand alone to control the engine, we have complete control of fuel and timing. We have a cut off if we go over a desire rpm, we have knock sensors cut off, over boost cut off, etc. etc. Remember a lot of the modifications are custom, custom manifold, custom fuel rail.
You would see on the picture two cables the factory ones and the cables from the stand alone ECU.
Please don't ask me about which ECU we're using I can't tell anyone this is a top secret, our mechanic spend long nights and months put all this to work and this is business for him.

Sorry,

Manuel

mike1324a

i need to clear something up are these numbers to the flywheel or to the wheels?

zoom44

wheels

IZoomZoomI

so what ecu are you using :D

RX8PR

I think that there is a few ECU that can work with the RX8
the problem is that you need to customize your work.
Right now you would not find a plug and play one on the market..............
but with time you would see them...................

Manuel

RotorManiac

dammit Manuel, first the girls, now this! you are tempting me again to move to PR

can't agree with you more... the 997 S runs the 1/4 mile in 13secs flat and 0-62mph in just 4.7secs... I don't think a stock STi can catch up with those numbers.

LiL BenNy

sti 0-60 is 4.3 i believe but runs a 13.4? close enough to say it would depend who the better driver is..

Fanman

No, the stock 997 S has run 4.1 sec. 0-60 with 12.3-12.6 1/4 miles @ 112-115. The magazine that pulled a 13 flat from the car, also had a C5 Z06 running a 13 flat. An STI stock for stock will lose to a 997 Carrera S. Under .5 sec. I would say is close, but when it is .7-.8 sec. faster that is substantial, with the difference growing wider past 100 mph.

RotorManiac

the times I said above are on an ordinary street, not factory ones that are made in perfect conditions while raping the car. I also said 0-62 cuz we europians count with kph there is a small diference in that... its the same with the rx8, I think its impossible to get 5.9secs it is said it can achive. A 6.2-6.4 is more realistic in my opinion...
still, the point is the same. there is no comparison at all. especially over 100mph the 997 will be long gone. even my 8, when it was stock, at full throttle above 100mph could stay very close to the euro spec STi. I tested it with a friend of mine, and he was amazed
