RICE RACING

Forcefed7 writes ......I think maybe you missed my point. Boost pressure is only one part of the picture, as I'm sure you know that pressure and flow (volume) are two different things. Does his car make 604rwhp@23.Xpsi? Yes, as you can see it did. Would his car make the same 600rwhp running a solid 23.Xpsi evenly across the board? IMO yes.


^ That is the stupidest thing I have ever seen posted anywhere from someone who is meant to know about engiens LOL !!!!!!!!


I will bet you $10000 to the contrary, it will be NO WHERE NEAR THE SAME POWER.

You need to go back to school and learn the effect of boost pressure and torque then its follow on effect to peak hp.

Sign of the times I suppose and a true reflection of the skill base *sigh*

TooMuch4You

Insane powerband.... What's the ETA on the dyno vids?

RICE RACING

torque is directly proportional to boost pressure
P=(NT)/9.55

P = power (kw)
N = engine speed (rpm)
T = torque (nm)

Now when you have a decreasing torque or boost curve from high to low BLIND FREDDY can see that there is NO WAY IN HELL ! that a boost curve going from 28psi @ 5k to 23psi at 7.5k will yield the same figures as a flat boost curve from 5k to 7.5k.

If you your tuner or other bandwagoners cant see that then there is no hope for you nor me posting anything of merit in the persuit of basic level engineering fundamentals in the interst of knowledge.

Its a FALICY to claim X rwhp on some boost when it starts out so high and tapers back down and then say it will do the same on the lower figure, It will NEVER do so and to claim it will is plainly ridiculous and decieving

The owner asked for critique and I am providing it, unlike the hype merchants it will withstand ANY independant examination or test (please do it and prove me wrong) LOL.

Again Congrats on the number and I hope people understand the reasons behind it as well and are not coned into believing it wil happen on a flat boost curve on the lower quoted figure for it simply will not.

Maybe it did, but there's more to it then just a "street port". For example, what compression rotors did they use to achieve that? I can tell you considering Peter sponsored his RX-7 and it was not some off the shelf stock 3rd Gen"

AGAIN 100% total bullshit by you !

December 1997
Adam Saruwatari
Stock std FD3s engine
Street porting by Dan Paramore Racing (dont make me post pics ! I have them !)
exhaust porting by Jess Morton
Rotors Stock
Apex seals Stock
Extrude honed intake manifold
PFS supplied the piggy back ECU and thats it.
Engine dynoed 550rwhp @ 7250rpm on 1.3 bar 19.1psi boost on Kenne Bell dynojet Rancho Cucamonga CA with full exhaust
it was 100% dead stock off the shelf ******* engine, no special rotors seals or anything else !! only a bit of mild porting and inlet manifold honing
ran 132~135mph many times on 550rwhp all on a OEM stock motor with street porting

Dee, congrats on the build up. It started in the Gate, and ended at PFS. Have fun with it, but get the rest of the Susp., Rear End, yada yada. Anyways, enjoy.


Oh, and Ricer. Go start your own thread, gripe, bitch, and moan all you'd like. Otherwise STFU.

mr2.2liter

Killer poweband bro. Congrats for making 600whp. No matter what PSi you were running.






Lol come get some dead stop. You know where to find me

forcefed7

So we both agree to this equation, right?

(TorquexRPM)/5250=Horsepower

At roughly 7500 rpm his car made 601HP and 422TQ with a measurement of 23.89psi in the manifold.
What is misleading about that? Are you saying that "if" it had only held 23.89psi across the entire run it would have made less torque at 7500rpm? If so how and please explain why.

Where his car peaked in boost is about where the Torque value peaked, BUT not the horsepower.

Here is an overlay of his car at a steady 18psi. Measure the values at 7500 rpm where he is making his peak HP

17.96psi = 536.49HP
23..89psi = 601.02hp

HP difference = 64.53hp
PSI difference = 5.93psi

So his car was picking up 10.88hp per pound of boost increase at those levels. (64.53hp/5.93psi=10.88)

What doesn't add up about that to you?

If his turbo was capable of hold 27.88psi at 7500rpm he would have been somewhere around 640'srwhp

If you have all the details about Adam's engine setup, that's great, post some pictures. I was told his setup was a little different but all of that was before my time. Maybe he was making 550RWHP@19psi on a street port, but even then there are so many little variable that you can argue about. Maybe he was "ramping up the boost" that caused those numbers.

wow nice numbers yet again We need to come up with a sticky for all the 600+ rwhp rx7's out there. I was wondering when people would start down playing 600rwhp as they did with 500, seems like that time is going to be apon us real soon, lol.

^ prove it i think your full of ****. further more if your subject is off topic start a new thread and discuss the situation on your own time then you can cry all you want.

let us see your pull what is your 7 pulling

back to topic sweet pull. wheres that video at?

mr2foryou

Thanks guys. The dyno video will be up once I find the right cable to get my camcorder to hook to my computer.

I'm sorry to everyone that's reading this thread, that I've caused all of this arguing. Plain and Simple: my car made 604rwhp @23.55psi(no matter how it got to those numbers). END OF STORY.

BIG THANKS again go out to RAY WILSON of PFSupercars in Frederick, Maryland. I couldn't be happier with my car.

Dee E.

crispeed

No it did not. It made 601.86rwhp @ 23.55psi!

Asleep

Nice job, regardless! The GT40XXR family is proud of you.

RICE RACING

AGAIN, your lack of knowledge is painful.

What happens PRIOR to the power peak influences the peak power point further down the chain, especialy when it goes from high to low, for this simple fact you will never ever get the same power on a flat 23.55psi V's a 27.88psi taperign down to 23.55psi.

go do the math, better yet go do a dyno plot and try to proven me wrong

you wont be able to

HENCE YOU CANNOT CLAIM TO MAKE THE SAME POWER NOR THAT THE POWER WAS MADE RUNNING 23.55psi AS IT WAS NOT.

IF YOUR TQ PEAK WAS AT MAXIMUM POWER REVS THEN YOU WOULD HAVE A LEG TO STAND ON ! but its not so you or any other bandwagoner is either ignorant of this simple fact or trying to decieve people, i'd guess by the quality of contribution put forth you are all very ignorant and quite un learned about engienering and history

Asleep

Both of you are like trolls on this thread. Take is somewhere else. You're ruining the purpose of the thread. Maybe a nice mod will suck all this noise out of here.

crispeed

Why is it every time someone post up results of a high horsepower car there always have to be some drama involved. Everyone should be happy for the the individuals involved.

And remember, dyno numbers are not always as important as everyone believes.

If anyone should move on, its RICE RACING, Ray (Forcefed7) has every right to post on this thread as he was the one who freaking built the motor and tuned the car, and when someone hi-jacks the thread and insulting him, hell yes he is going to respond. Point is, maybe Rice racing is a little envious of the success stories coming out of PFsupercars shop, point in case, customers cars making over 600whp, not shop cars that are expected to make great power.
Rice, honestly, if Ray didnt know what he was doing, do you think Mine or Ernie's car would have made the numbers they did and let me tell you, I ran my car hard on the street and never had an issue, same with ernie as well, or the 100's of other satisfied customers that he has tuned, not only RX7's, but the IS300's, Supra's, etc...? Come on man. You really are trying to prove a futile thing here, basically in my opinion and most everyone else who is reading this thread or experienced rays work, and the ones who know because they have been there, its all about you trying to prove some ego of yours....thats it, or else you would have kept your opinions to yourself, as you seem to try and over simplify the technical aspects given. It is in fact you who seems to be doing the hidden agenda here. Anyway, I do hope people here realize what is going on, and Dee, sorry Rice Racing has to even post his egocentric issues here and to try and flex his.....
Good luck with the future mods to your drivetrain man. Hope to see you at the fall brawl.

I might get talked about for this one ,but I will say that in my opinion I don't belive that a 2 rotor can make 600+ rwhp @ 23.5 psi. thats all I will say about the PSI drama, on another note who CARES you made it, and thats alot of power
I bet that the car HAULS **** and thats what matters. O yeah......... and it idles after all that boost !!!!!



congrats

BLitzed33

first, bridge port baby, you are allowing more volume of air to be induced by the motor at the same given boost thus making more power at a lower psi vs a street port, second,, its volume of air being pushed, a small baby turbo like a K03 at 10 psi will not flow near the amount of air as a T88 at 10 psi, or for example, your stock twins boost 10 lbs of air on the first turbo, when the second turbo comes on, you are still boosting 10 psi, but you doubled the VOLUME or air going into the motor, so psi sorta becomes mute, see now?

dammm u know after thinkin about it my "goal" is to make 650-700 rwhp @ 30 psi w/ my setup, not saying that mine is better I think I will keep my comments to myself ? cuz if I meet my goal the BS flag will be raised. so after ur post I WILL TAKE IT BACK , "too many beers" good night


MY BAD I promise not to post after a "FEW"
