Hi guys

I have an FD and just got a loan from bank and want togo all out on the car.
Can anyone tell me what are the well proven MODs that makes the engine reliable and needed to achieve 450rwhp@15psi with GT40R or can i achieve more?

Im in australia ill be running on 98octane.

Thanks alot

 

I doubt the GT40R will get even close to 450RWHP @ 15PSI on an australian dyno. Most of you guys use dynapacks down there and generally HP figures are lower. I would be real happy with close to 400RWHP with a GT40R on a dynapack.

 

But that would only be the reading, the car would have 450rwhp if in us right?

 

I don't think the GT40R would be able to make that much power on a dynojet with only 15 psi boost either. Not very many people have tried it out yet but I think its more around the 400-430whp level for that boost.

 

oh ok, thanks alot for that, also can you tell me what other mods i need that are good to support the power?

Thanks

 

well, with the 98 octane maybe you could advance the timing enough to get 450 in the US?

 

anyone ?

 

for 450 at 15 psi, you need a big port and a big (somewhat laggy) turbo. I'm not sure which one, but to throw out some to consider that might get you close .....

T78, T66, T04S I doubt you'll make 450 at 15 psi, but maybe at 16 or 17.

If you go bigger, you can probably get it at 15 psi from something huge and laggy... I don't know what though.

 

I would go with a half bridge to help you get to that power level at 15 psi.

Im definately with you on this one. The R85 is the best bang for your buck turbo kit out on the market right now. It is 3150 right now, and it spools faster than a t78.

ok the turbo ive chosen is a GT40R but apparently this sort of power 450rwhp@15psi is not doable correct?

Then what sort of power will i get with a street port and GT40R between 15-20psi?

 

ok ive already chosen a GT40R but apparently with this turbo 450rwhp @15psi.
Would anyone know roughly how much ill make with a street port and a GT40R between 15-20psi?

Thank you

 

The GT40R may make ~450 rwhp @ 15 psi... it also isn't peak power that is the be all end all. You want a strong power curve, wait until the 40 is dynoed...

 

Sorry but until I see more proof than one dyno, I think we should evaluate all the choices. I'm not saying it's a bad turbo... I think it looks good too, but when the only results I know of are from the guy selling the kits... come on people!

I'd like to see 3 or 4 results on that turbo before I recommend it to anyone.

 

Anyone know the boost levels of those two dyno charts? Hmmmmm I wonder how well this turbo would perform on a 20b?

 

The first dyno was at 15psi, and the second dyno was at 25psi.

Damn I feel like an idiot!!!!! It was plain as day on the dyno plots.

 

Really im building a race car now with at Trust TD06H-25G turbo, and im aiming for 450rwhp at 15psi.

I was in england 2 weeks ago and i was at maybe one of the best rotor builders there, and he had a streetported FD with the same turbo, and it was pulling 430rwhp at 12-13psi. So it's not unbelivable.

Il be tuning mine the 21st so il let u know then.

Really? 430RWHP in England is 450 plus in the US......Hmmmm. all this from a 25G at 12-13 psi.....Hmmm.

 

well there is that car from NC that dee's been working on... we'll have another guinea pig when thats done.

 

people with small turbos are always jealous isn't that right wagasm

 

I'm interested in how the new kit is going Dee, any results on customer cars yet or are people still working on them?

Haven't gotten any feed back yet. Just curious as why you would question my integrity on my dyno sheets?

I seem to be one of the only tuners to provide a dyno sheets for my own turbo kit and do not rely on my customers or other shops to tune my kit, but it seems like you are damned if you do damned if you don't. For example when you get better then average results someone like yourself "don't take this personally" questions the validity of the results and when you do not provide they ask where are the results.

Why is it so hard to believe that if I can make 770rwhp at 30psi why can I not use the same technology to produce 450rwhp at 15psi. Dosen't your t04s make 400@15psi all I have to do is flow around 5lbs or air more at that given pressure ratio to make the extra 50rwhp. And I am fully aware there are some shops out there that say this is not possible but these are the same people that can't seem to reach the numbers I am making on my race car but I guess that is fake too.

Does greddy ship a dyno sheet with there t78 or t88? Does hks ship a dyno sheet with the t51r?

Seems like certain people want to hold others to different standards then some. If you had any idea of how much time I have spent on the dyno and how much of my own money I have spent you would not be on this forum bashing the results of the R85 every chance you get.

Because you are from maryland I am personally inviting you over to my house to watch me tear my motor apart to show you how I port my motors this should address the issue of we have no idea what is going on in dee's motor so we don't really know the true numbers for the kit.

Matter of fact the sooner you get here the better as I am working on the car right now myself and need a extra hand as I would like to make it to the dyno by friday.

You can reach me @ 443-745-5911 I will be waiting for you phone call

i believe you make the power but why dont you pick up the phone?? i just called....
