15 psi boost with 93 oct is very safe, talk with John when he returns from vacation for fine tuning tips.

+- what WHP @15psi

TRP951

It depends on the turbo you are using and many other variables to know what whp you would be running at 15psi

My car is stock, I order the vitesse stageIII with injector WG everythig John told me.
I don't know size. This is the first time I do something with a euro car.

John cautioned me about running over 15PSI on pump gas due to possible back pressure caused by a inefficient turbo on the hotside and detonation problems due to hot gasses being forced back into the combustion chamber.
However, I am running a Garrett Hybrid and while adjust boost, it turned the screw a little too far and it pegged my 25PSI gauge (probably 30PSI), there is no stop pin and did not miss a beat. Pulled like a drag car. I immediately pulled over and turned it down. I have it set at 19-20 psi right now and runs perfect, did an autocross yesterday with it in 95 degree weather, without missing a beat, perfect cold starts, high load low rpm, QUICK boost build, full boost in 4th gear by 2950-3000 RPM. It also builds full boost in lower gears where it would not with the AFM, if I had it set at 18psi, it might build 14 in 1st and 16 in 2nd, now its all out in all gears.

That the same turbo that john is going to send me?
And what the whp with 15psi in your car.

No my turbo was sold by Huntley. They are now out of business. John builds his own turbos to his specs using garrett. Don't know the specifics.

I have not talk with no body who have this kit yet, just with John. who by the way look like a very nice, and right person. Do you know who I can get in toch that have this kit.
I'am going to use my car for solocross and open speedway all day @ 100F temp.

John can sell you the turbo, MAF and chip. This will give you a tested package with many hours design time and thorough testing. I am very please with what John has provided and feel that it is money well spent.

I all ready bought the stageIII kit. MAF, Turbo,chip,PB,Injectors etc. I want to know what to expect.

TRP951

look at posts by special tool he has the stage 3 kit, and before he swapped his head he was making something like 437rwhp at 22psi

jlturpin

I would expect a HUGE difference. I just got the MAF and Injectors, LOVE it.

porshhhh951

if you have all the supporting mods I would think you would be all over upper 300's on 15-16psi and pump fuel with a full stage 3 from john.

Personally I am thinking 430-440rwhp on 23-24psi and c16 or maybe some water

juanchovidal

that what I'am looking for.
thank you very much.
