Paul can chime in with what weight reduction he has. I know he has a lot, but not sure exactly what's done.

Very nice!

So it makes 425whp max? I am asking because at that weight with that whp is kind of hard to hit 127mph. 123-124mph seems logical.

Maybe VD on the dynojet setting reads lower for us?

Again great job

Look at the weight and tire size i used for his car. He doesn't know how much it weighs, he was guesstimating weight and tire size from wear.

If I use stock weight and tire size vd is up in the 460-470 range.

Juan check out what total weight and tire size we have inputed. its a 225 45 17 tire but its super worn so we guessed 24.7 and also guessed weight, that pull posted was with a 210 lb passenger and myself (about 150lbs) so its prob actually higher. My local subie shop offered me a free dyno pull whenever we are done tuning it since they were impressed and curious at the same time. Its just there about an hour away and iv been busy but ill get it up there soon.

Ill post pics and more info here soon, but the car is an absolute blast to drive. I Spent several months slowing putting together this car in my garage then took along time to decide who I wanted to get tune it but I can honestly say going with an Etune with Ron was the best choice, since he can dial your car into perfection from various pulls in multiple different conditions and days instead of just taking it to a shop and have them spend 2 hrs on your car 1 random day and be done with it. Ron is superhuman fast in his responses and map revisions... idk how he does it lol

Time for the eye candy...

Nice job RON

Those smaller GTX turbos make such nice TQ bands. ET/MPH all day long!

Thanks jr. We were hoping for 10's, but that trap was shocking to me. I thought he was going to be at 122 max based on the vd. Must be a little heavier than he thought.

The weight could be right. If the TQ band is broad ( like this one )and turbo can male power all the way out the RPM they tend to ET/MPH better, especially with a good driver. Car doesn't loose momentum.

Kinda like a 4k lbs GTR can trap high 130s with 600whp, small turbos, lots of TQ and a transmission that keeps the car in power on every shift.


I bet this car can go 10s with a good 60ft

Awesome powerband and numbers from a tiny little turbo!

Isn't this allegedly only a 47# compressor?

Yeah I built this one for response and to have a big powerband, I hate lag... I couldnt find any info on people running a gtx28 on a subie and hardly any info on people even using normal gt28 and most people were saying it would be stupid to run a gt28 turbine on these things lol. Anyways I was very impressed by the massive tq band and especially how little the tq drops off.

I had a 05 STi stock turbo setup about 2 years ago with 93+meth plus tons of bolts on and made 411wtq/364whp. This car literally feels like it has better response then my stock turbo setup 05 STi on the street, and it just keeps pulling and pulling super hard up top.

Yesterday I went to track first time in this car and my first pass I trapped 126.80mph with spinning first super hard, lol I think that run had like a 2.1 60ft. I couldnt believe the trap speed thoe me and my friends were stoked. I was just thinking WOW this thing could run 10s. Then I immediately texted Ron and said "wtf is 126.8 mph good for a first pass?" lmfao!

Diesels don't use bpv's and that's what the anti-compressor surge housings are for

Bpvs or bovs just cause leaks and make you sound like a ricer also almost all race cars dont have a bov or bpv just ask crawford. They never had a turbo fail from this either.

Diesels also don't have throttle bodies.

Well, Paul and I talked before the tune about it and I voiced my opinion against it as well, not based on any facts, just purely off never having tuned a car without a bpv/bov.

I guess Paul can speak to it better than myself since I've never even seen the car lol. But he never reported any surge or negative effects.

Honestly I think it makes your car have less "shift lag" (for lack of a better term) from not blowing off all the pressure in the system so fast. Also the car feels smoother when you do a pull and just let off the throttle, for example the car dosnt feel like it jerks forward as abruptly when you let off. This is good when entering a corner on a track because your car will not get off balance as bad and will stay smoother, *which in turn*(see what I did there ) equals more available grip. This might be an extreme example but every bit adds up in the end. I could be completely wrong and this could be all in my head, im just sharing what I feel thoe.

Crawford must not run one on a single car they have ever built for a good reason (even on non anti-surge compressor housings) Also I don't see any negatives only positives to this. The only negatives posted are just from 99% percent of people explaining how turbos work then saying your going to blow your turbo if you do that, but I havnt actually seen a single review of someone actually blowing there turbo from doing this... lol. Pretty much if your running a strong reliable turbo like an OEM turbo or a Garrett you should have no worries, but if your running a Borg Warner I wouldnt do it... haha jkjk

Thanks. I went thru Curt Brown, but he can only do the fronts not the rears on 04-07 STis. I think he can do all four if you have the unboltable style rear hubs found on the newer STi's and WRX's.
