fp red or 35 r

 

GT4088R twin scroll

 

35r with .82ar hotside

 

Very true, I had this turbo on my 2.3 and it was really fun, makes alot of power

 

FP red ftw.

 

actually, I change my mind. VF39 all the way :-P

 

wohoo, so many posts- thank you guys.

Well someone asked where I want this car to perform. Well I am not a drag racer. I race this car on local closed race tracks. The car should acheive max boost at 3800 rpm the latest.

Here is my current dyno:



For some unknown reason I dont really want to go with the FP series turbos- i dont really trust them. What I would like though is a ball bearing, external wastegate turbo capable of around 500-550 crank HP, I dont need more cos that would also mean later spool up, and bigger turbo lag. I dont want to use ALS all the time if its possible.

Anyone here with the Tomei turbo? What is the max power out of that turbo?

 

nice numbers on such low boost. first off start with increasing your boost say around 1.75bar maybe higher depending on the capability of the tuner. if your goal is just 500hp then a 30r would be enough. but i would personally go for the red or the hta35r. goodluck and keep us updated.

 

Are you looking for a bolt-on turbo, or are you going to swap out your exhaust manifold as well?

As I said in my earlier post, a 3076 will easily hit the numbers you're looking for, and should hit full boost before 3500 RPM. However, I still think that a well-built HTA3582R mated to a 2.3 is about as good as it gets for a road-racing setup. As an example, on a 2.0 the AMS kit with an HTA 3582R is capable (depending on cams/tune/header, etc.) of hitting full boost by ~3900 RPM ... that's on a 2.0. On a 2.3, it should easily meet your full-boost-by-3800 RPM requirement.

I don't know why you wouldn't trust FP, they seem to really take care of their customers. The new FP red with the 80mm anti surge housing would be incredible. You would love it. That or the HTA35R as everyone has also said. Or if you want to just do it right the first time and be done with it, the 6262.

 

In Europe, pump gasoline is rated using the Research Octane Number(R.O.N.) method. In the U.S., octane at the pump is measured by averaging the Research Octane Number and the Motor Octane Number(M.O.N.):

(R.O.N) +(M.O.N.)/2

European 100 octane pump gasoline is roughly equivalent to 93-94 octane U.S. pump gas.

 

This prediction just seems slightly optimistic to me. Just exactly, what would ,"peak boost", be in the two above cases, Ludi?

If it is possible to get a 35 to spool to let's say 26 PSI, before 3800 RPM, then this would indeed appear to be a good turbo choice. I am just not convinced that you can hit 26# below 3800 with a 35, even an HTA, and even on a stroker. Especially not on a pumpgas tune.

 

If you take one of my old dynocharts from my stock ECU/50 trim days and overlay AMS' HTA 3582R dynochart, you'll see that the spoolup is pretty much identical. In everyday use my stock ECU/50 trim setup used to hit full boost (24/25psi) by about 3800 RPM (+/- a little, depending on the gear). Both dynocharts were generated from almost identical engine setups (AMS built 2.0, VSR intake, AMS IC, etc.). That's why I think hitting something like 26 psi by 3800 on a 2.0 should really be no problem. Then when I take one of Smogrunner's old dyno charts (35R on a 2.3) and overlay it over mine, it easily spools 300 or more RPM earlier than my setup. So full spool by 3500 on a 2.3 should again be fairly easy to attain. Of course it all depends on the supporting mods (cams, intake, exhaust manifold, IC, etc.), and I am talking about attaining those spool numbers on the street, not on a dyno chart.

I've been in an 2.0L HTA82 car, there's no way that setup is spooling by 3900.

 

Which kit?
