Is my goal unrealistic? Anything I should change/upgrade. First build ever. Any input appreciated. Plan to tune on E85

 

Looks like it could make 500, but I think you could see some good gains with some bigger cams. Everything else seems pretty solid.

 

500 is doable with that setup. I second the cam upgrade

 

With that large of a turbo and GSR camshafts, he's more than good. True, there are better camshafts, but what he's got will work just fine .

 

im surprised i get to be the first to point this out..


but the 38mm wastegate might be a problem.

 

might be a problem if he is trying to hold low boost pressure but looks like he is shooting for 500 whp which would take 18-20 psi...38mm gate is fine

 

that's predicting a problem that hasn't happened yet. It all depends upon what boost pressure he's going to go with. In his case , about 18-20psi for 500whp, but yeah... could become an issue depending upon timing and boost control.

 

I find it funny you mention timing with boost control now.

Ever since tepid pointed it out.

 

Umm sure..that's fine.. I never discounted the fact that retarded tuning control was is a factor.. but it was actually my good friend Tony L reminded me of that factor, in conjunction with proper boost control systems.

 

actually from the looks of it, it might be able to do it because of the compressor housing size..


i was looking at the ex numbers.

 

There are people way before me that pointed it out as well. Who cares?

This setup is fine for 500whp. I, personally, would leave the GSR cams. When you start getting into aggressive cams then you need to start thinking about a better block. Keep it simple and keep it fun. Aggressive cam ramp rates will only lead to more harm then good in a stock rocker setup. Just my opinion.

 

The housing doesn't have much to do with it as you think. Its the fact that its a turbocharger that has an airflow rate of over 61lbs/min at 2.0 pressure ratios.

 

Pretty much.

 

I have always thought this as well. At 500whp you are making more HP than you can put down in a FWD platform as it is.

 

actually, the reason i was thinking it may be a problem was because i had to upgrade from a 38mm to a 44mm to prevent my t3/60-1 from spiking uncontrollably. i did a google search on a gt35r and a few of the first ones i looked at had larger compressor housings, so i figured it was possible it could produce more boost/hp while requiring less exhaust gas to drive the .63 side..


although i guess technically i am speculating mind you...seeing as how i dont have a gt35r...perhaps some people i used to run with would know from personal experience..

 

The area ratios for the stock GT35R haven't changed in almost 20 years. The look may seem different (some had ported shrouds, some were Precision covers, etc), but even if it was altered to have a T04E cover, in this instance, it would make no significant difference at such low speeds for the GT35R to make power.

 

looks fine to me. im lower compression than you but on an hx35 mine makes 481 on 20 pounds of boost with gsr cams. but i am on an ls bottom end rather than a b16.

 

You do realize that spiking and creep come from the turbine side rather than the compressor side of things, right?
And that a larger compressor housing doesn't mean that it will make more "boost/hp", right?

Your words.... not mine.

 

500 might be pushing the boundaries on stock sleeves.

 

It's all in the tune. Managing cylinder pressure is the key to keeping it alive. ROC (rate of change(in cylinder pressure)) is the reason for failure.

This image says it all....

 

while you are correct, id still feel like its great insurance when you are already spending many thousands of dollars.... just my .02

additionally, would you guys run that top ring at that, or open it up to around .020?

i would not run any rod bearing at or less than .0015, ive seen some get worn pretty good around there, maybe try and get them up to around .0017-.002, again just me

 

Loose is fast.

It's a good rule of thumb.

Additionally, it really depends on the fuel being used as to how to gap the rings.

 

Thanks for all the input. Is there a way to tag someone in a thread like on facebook? Haha. I know my tuner is on here and would like to hear his thoughts. Its Mikey from Profunction. Believe his username is MikeySpec

 

Mike has been around for a while. I'm pretty sure he knows what's up.

No way to tag him.

 

you werent paying attention to the whole conversation.



dont be a dick dude.
