From what I have SEEN and witnessed, the difference between a .63 and .82 on a 30r (3076) is about 3-500 rpm. I cannot attest to the differences in top end power, but from what I have witnessed with others going from smaller to bigger exhaust housings, once pushing the turbo to it's limits increasing the exhaust housing is basically shifting the turbos powerband to the right and up, at the expense of some response and spool down low.

( this is a guess) But I would say going from the .63 to .82 would be a couple hundred rpm in lag in exchange for more peak power and maybe more ability to maintain tq if the turbo is really being pushed.

I am interested in finding out more details about the HTA green somebody mentioned.... anybody have info on that? So far I can get a green + meth for half the cost of a HTA 3071 kit...

unfortunately, not much info....but there's a lot of talk about it in this thread.

 

Anyone have any dyno sheets on the HTA 3076 .63 and HTA 3076 castmanifold?

Intrested in seeing the diff between spool and hp.

 

Any updates on this?

 

What updates are you looking for? DB installed then tested the turbo, posted the results and then took it back off.

 

I believe that thsose are really good numbers on a smaller turbo that most people don't believe can't make alot of power. 22psi and 485awhp on this turbo is very good!

 

Just reading through this, I think everyone was interested in seeing some videos, as well as some results on a more stockish EVO vs. a fully built EVO. Not necessarily asking for more info from DB but perhaps anyone who has experiences with this turbo since this thread was started.

Anyone besides DB try one?

 

I love my HTA30R.. gonna step it up in next spring to the HTA 35r with a built motor ..but for now im gonna enjoy it this summer.sean ivey is tunning her tomorrow morning.

 

any chance of seeing the HTA3076 vs the standard 35r? this would really show the difference in response.

 

WOW what a great thread. How much is gained/lost with a .63 housing Vs. a .82 housing on a 35R?

This Thread shows that the 35R KILLS after 5000RPM's, which is where you will be if you race. I got my heart set on the 35R

 

Matt we all know u love the 35R talk is cheap...go buy it.
diffrent stroke's for diffrent stroke' s my brotha..who care's abouth the 35R! were talking about the 30R .Of course it makes more power than a 30R is that ya point? it's a FACT already.i personally are going to have the HTA35R nest summer but only with a built bottom end.BUT my car is far from a slouch. u sit here and bash it everywhere u post ...lol meanwhile your on a stock turbo..

 

Ok, lemy just shell out that 5K for that Turbo kit+install+injectors/fuelpump/tuning............Know I got it somewhere....

 

Damn buschur HTA 30R kits is 800 cheaper then AMS's HTA 30R why is that?

 

I agree.....thats great numbers
