I'm talking about nobody else addressing it to the OP. He's going to need it or else he's going to have a bad time trying to get above 430whp...

I know, I'm talking about his build in particular. 475 whp with only cams as a fueling aid, I don't see it happening.

He is built like the OP and has done enough work to his car to know what goes bad. That 440 torque is enough to kill the ZFR. Mostly it is about how you drive it, I never blew anything up. Except my ZFR

 

Someone's a hater.
Pretty sure he meant to say stock trans instead of stock turbo cause he did have a wr3 producing those numbers. Its the torque that breaks the trans. It spools too quick for its own good. Ask me how I know.

 

Ah. I havent been around long enough to know what people have done, no offense was meant.

I saw yours wert. ouch .

 

Lol no hater but with the damage it causes and it's limited potential I'd say there are better options

 

Yes stock trans has taken a lot of abuse. I know that will be the next part that I buy. No offense taken, I have been through a build quite similar and put out some pretty good numbers on only 93. I beat the **** out of my 3.83 with the wr3 and it will take even more abuse (mostly track) with the 6258 on e85. We shall see how long she lasts haha

 

There is better options, but for money and time you can't really beat it.

 

get a stage 3+ spec clutch and.fly

 

the ottp shifter is pretty badass I like it over my b&m

 

Tq kills the trans, not power. Boost ramp ftw.
Hit 400tq, ramp the boost to hold it till the turbo peaks.

 

^ Well that didn't work. Must not be true. Boom at 6k

You sure the damage wasn't already done?

 

Say you held it to even 350 tq.. That's still 535whp at 8k.

 

Yeah you could be right. I just think its not necessarily a certain amount of quick power. Its stress along the powerband. The zfr is lethal not just because of quick spool. It can put near 400wtq over a huge range...

 

It wouldn't make 530ish around 8k. Gains are diminishing the higher you rev. I think after 7.5k the s256et runs out of steam to hold 29psi to 8k. I would expect power to fall off.

See this:

If you have 350tq at 8k, then you have 533whp. It's simple math. It may be working a lot harder to maintain that tq, but that doesn't change the result.

 

That graph has tq drop to roughly what 355 at 7350?
355/5252*7350=496.8
Yeah it's not dead on, I'm guessing numbers on a broad graph. But that equation always holds true.

Tq*rpm/5252=HP

Ever notice tq and hp always cross at 5252rpm? That's why.

 

Lol...yeah around there...anywhere between 355 and 370 at 7400.

Good scientific explanation lol.

I have discovered this is was with a huge exhaust leak, and a wrong wastegate spring. Torque should have been 460ish at 4k.

I'm wondering how that will change the whole curve.

 

Manifold leak or post turbo?

Realistically it should shift the whole curve straight up but still fall towards te end.


I realize it'd take one healthy snail to maintain a flat tq all the way out. But one can always dream...

 

Exhaust manifold gasket and t3 gasket. Both pre turbo. Is on a 9psi spring. Will have 20.5 psi spring in it come April.

 

Why such a massive spring. No bc?

 

Yeah I run the aem truboost.

 

i was thinking bout running that controller but, it only goes to 30psi, decided to go with AMS400 i was also looking at a 20lb spring for my turbosmart but i think maybe a 15-18lb spring would be ok

 

There is an add on that let's you run up to 99 psi or something crazy.

NM 5 bar

In my opinion from running it you can control duty cycle on it to exceed 29psi. But after ~31psi your boost will not accurately read without the upgrade.

I like how I can switch between two boost levels on the fly or you can scramble boost if you are a crazy ****. Things I dislike - it works off duty cycle and depending on the day your boost levels are not the same everyday. You'd have to do fine adjustments everyday to get specifically the boost you are looking for.

One day boosting 26psi. The next day 25..that sorta thing.

Setting the wastegate spring crack pressure too high makes the car drive weird. Hence choosing a bigger spring.

 

Ok def sumtin for me.to look into, I dnt want to kick.out 600 for the turbosmart and the AMS500 is just bad ass like the two stage feature ramp boost featurespriced well monitors up to 41psi
