Mellon, can you comment on the spool differences between the two turbos? Thanks.

sorry but that's information I only share with paying customers that have a similar setup

I could have sworn that I read the the bigger HTA does give up quite a bit of spool though.

The HTA 3586 .82 definitely feels lazy compared to the HTA 3582 .63 in daily driving but on the track the respool is instant if you shift fast and you can't tell the difference. My advice, if you're going to stick with pump gas and 30psi...go with the HTA 36582 .63 it'll feel more responsive and make nearly identical power. If you're going to run 40psi + on race gas and are mainly into drag racing, then the HTA 3586 .82 might make more sense.

So that means you make 30 psi around where? High 5000's?

Thanks for the response, I'll stick with the 3582.

Just to give you another example: I'm making 20psi in 3rd gear @ ~4550rpm on a HTA3582 w/ .82 with stock 2.0L and 26psi @ ~4800rpm

sorry I came off dismissive, but I don't like throwing parts at a car just because somebody says "this will help". I don't have unlimited funds nor time to try everything that's out there. I'm doing pretty good with the 3" intake piping and I'm not finished pushing it to see what's left. I'll definitely keep the 4" pipe in mind once I max what I have out if I still want more power. Especially if somebody can provide some proof that it's worth the price.

It's nothing against you, I don't know who you are and your background...but this forum is full of bench racers whom make all kinds of claims based on what their buddy told them. I'm skeptical when I don't see any unbiased data (shops like to sell those parts!) to go along with the claims.

certainly when/if I do a 4" intake I'll be happy to share the results good or bad and give credit where it's due, sorry I offended you, that wasn't my intention.

damn, very nice. hta's seem to be doing very well!

Black35r8 · May 26, 2009, 03:17 PM

sick number I hope mine makes that

That's exactly the info I was looking for. Thanks

Very nice. I hope you get it all back together soon. I hate when my cars are down.

The turbo inlet discussion. The MAF coupling is 3.25" I believe, not 4". I'd measure it if I was at the shop. The turbo has a 4" inlet with the ported shroud. I don't know for sure but I would guess that the MAF right now is by far the largest restriction in the system. A 4" pipe may very well gain some power but the gains from losing the MAF are going to be MUCH higher. Have you considered running the stock ECU with speed density yet? I want to make the switch soon but want to finish off what I think I can get out of the stock MAF first. In your case it makes sense though.

If you want to try a 4" pipe just say the word and I can fab something up for you and send it over. On the AEM with speed density we had a car on the dyno in the 550 whp range and switched from his 3" BR double bend MAF pipe and open filter to a 4" single bend MAF pipe and filter (no maf being used) and the car gained about 12 whp.

ripnbst · May 26, 2009, 05:44 PM

These results are super impressive.

R/TErnie · May 26, 2009, 06:24 PM

I agree with dave... removing the maf altogether would help much more than making a custom pipe to the maf. I have yet to switch to speed density using the stock ecu... so we'll have to see when the time comes

Congrats on the power

must be fun!

Like you David, I'd like to finish up the tune on the stock mas before I consider trying something else like speed density or even the 4" pipe but thanks for the data and offer to give it a whirl. I may take you up on that later.

12whp is worth doing, did you run into any snags with idling related to the 4" pipe. There was another shop sending me PM's that couldn't get it right until he went back to the 3". I'm not familiar with that shop or their tuning abilities so it didn't scare me off. Also that was on a stock ecu, not an AEM FWIW. I think we can agree that with the stock mas in the way, the size of the pipe leading to the turbo isn't going to matter as much as it would on a speed density setup with no other obstructions.
