It's actually on speed density now, sorry I must have left that out of my update. I think I could probably efficiently boost 25psi on my top mount and that would be plenty of power.

I don't particularly like the idea of removing my front bumper beam.

My short term plan is to replace the clutch, and perhaps drop in a built short block before the end of the year. There's nothing wrong with mine, but I don't want to end up stranded somewhere from a piston failure.

Wow thats odd. My Hta green hits peak tq @ 4k rpms with a fmic. Are you running el headers?

My peak torque now seems to be around 4100 rpm. It was previously 3800 rpm, and I have a feeling that if I get a proper dyno (w/o slipping clutch) run on the meth map, that the meth map will peak at like 4800rpm.

I do agree that baisesti's peak tq should probably be lower in the rev range. Probably should get an EBCS and EWG if he doesn't have them already.

Wow u saw 22/24 increase off just 1psi on ur 50/50 meth map from ur 93 map. With a non slipping clutch,a fmic and 25-27psi you'll easily hit 450 and that thing will be an animal on the street

Life update: I had the car retuned on May 1. Here are the 93+50/50 meth numbers from the 32nd dyno pull in a row (heatsooooaaaakkk)

This is with an aftermarket clutch and lightweight flywheel. All other mods are the same as before. For whatever reason the car sounded a lot louder this time, but nothing has been changed with respect to intake/exhaust/whatever. It did also break free from a dyno strap and almost go driving through the shop which was pretty hairy for a second.



377/382 is pretty decent in my opinion considering warm day and insane number of pulls.

I'll be going back in the next few weeks to open up the EWG and see just how much I gain. My theory is around 30whp but we'll see.

I pretty much have the same set up as you. I made 357/367 on a dynojet... peak torque is at 4350rpm.

It is a very fun setup. That must be a low reading dynojet because these turbos make a lot of power - either that or are you running very low boost?

I'm running 21psi. It's a stock 07 sti motor with 100k on it. I don't want it to blow up. Yet. lol

It's definitely a fun set up for everyday driving.

Yeah, its missing from the chart. 22.9 psi. The backpressure from my ewg reroute is killing hp, or at least I think so.

My downpipe is taking a little longer in ceramic coating than I expected, but in the meantime look what has arrived!



An external wastegate muffler from a 1987 Porsche 911 Turbo (Porsche 930)! Hopefully my downpipe comes in soon so that I can get this welded on and a retune done.

It does make a difference.

I had an EWG on an hta68 (c/w TBE) and I had it plumber back in, it made about 3 whp less plumbed back in for me.

I got this one on ebay, but you could check wherever used 930 parts are sold. There are also probably plenty of aftermarket solutions (tigwerks ewg mufflers, supertrapp, and the like).

edit: and there's this for the low, low price of $795 (lol) http://www.ebay.com/itm/Porsche-965-...67fb85&vxp=mtr

I wonder what kind of gain I'd see with the 10cm hotside over the 8cm.

Why wouldnt you go back to the same dyno/tuner..for repeatable results. Also this is the same company that just posted how low there dyno reads yet this time around the numbers are more in line with shop x...hmmmmmm?
Either way looks like a clean pull

I can't speak about the way the dyno reads. I haven't studied the output and I don't have a "before" baseline there.

I don't have any hard feelings about the prior work or tune at PAS.

I'm not surprised the numbers are higher though, the old motor was tired and now the boost is a few psi higher. I had a restrictive ewg recirculation (my idea, not PAS) and that hurt peak power. The car is cammed now and wasn't then. Higher percentage of meth now too. And it was catted last time, not catted now. Apples and oranges, I think.

I can go dyno it at PAS, if you want, internet person .
