and also on the setups with the ppl putting 350 down what size turbo and how much boost they running? im thinking a t3/t4 57trim or 60 trim, or a sc61 or sc34. and run 550 injectors.adrians_s13 wrote:I'd say around 350ish... Just cuz I know people with putting 350 at the wheels w/ stock internals...
then I've seen people putting down like 400-500, but when I read the mods list... its like forged pistons n such...

More than likely high EGTs caused your failure. When doing topspeed like that EGTs tend to rise which will lead to the motor failing.Sil80315 wrote:It all depends on the motor, like how much abuse it took, how many miles it has, and just an all around gerneral look over the motor..
I picked up a spair block that looked mint..and probably only had about 40k on it..all it took was 9psi and one top speed run of 160 then BOOM blew a rod out of the side of the block and destroyed the crank
This is what happens when you get an sr that was built at 4:30 on a friday at the factory
350whp is easily attainable on the stock bottom end, and is not, by far, the most you can go on stock bottom end. Right now Im making 511 whp on my stock bottom end, which was my daily driver until a few months ago. This was done with an SC61 with Z32 MAFS and 750cc injectors. My setup is coming apart right now to actually build the motor so I can make some new real power. My car has been over 500whp for a couple years now.adrians_s13 wrote:I'd say around 350ish...

If you ever think you may want more power than 350whp, start out with a Z32 MAFS and 750cc injectors, this way you dont have to upgrade your fuel system if you want to upgrade your turbo. I wouldnt use an SC61 unless you wanted well over 350whp. at 10# the SC61 is not even close to its efficency range. I only made 302 whp @10#. At around 15# the turbo is in its efficency range and will work much better. If you want 350 it would probably be the least expensive to get a T3/T4 57 trim, or the 60 like you said before. If you want more power though, go for the SC61, it is a geat turbo. I am still going to use it at first with my new setup.mra4886 wrote:and also on the setups with the ppl putting 350 down what size turbo and how much boost they running? im thinking a t3/t4 57trim or 60 trim, or a sc61 or sc34. and run 550 injectors.

There is no "max duty cycle" injectors will run at above 100% duty cycle, they just wont last too long. But I know of people who have pushed over 115% for months without issue, I personally just don't feel comfortable running much more than 85%.92SR20S13 wrote:Impossible^^...your maf wont read that high and im pretty sure your injectors would be at max duty cylce
