77 Horsepower!

ok people pick up a magazine please. turbo dyno shoot out on wrx turbo back. the whole system netted 70 80 hp over baseline stock wrx.4 banger turbo cars benefit more from bolt ons that your 4 banging NA cars. Seeing how the first 3 big power mods should be turbo back exhaust intercooler and boost controller on this car. even recommended in sport compact car review of the top 8 cars under 20k issue.

The most realistic reply so far
.. The only thing- don't use magazine references- it looks bad since most of them are a joke ...the only thing I disagree with is the IC replacement as a first mod- K&N, boost and then exhaust.. Oh yeah- and do something about the excessive fuel whether you do it youself or buy my FP reduction kit- that will help a lot up top under boost. The stock IC is good for this point unless you are doing a lot of sustained WOT driving (road racing and such).. This IC is more than adequate for the dinky turbo we have.

77whp??(hmm)
Ok I was directed to this thread via PM.
So you figure 2 more psi of boost, an intake and exhaust will give you about 25whp. That is untuned and not modifying fuel maps ect. This sounds very very very very (you get the point) fishy:bs:
I need to see the sheet on this one and we all no dynos can lie

True however we are not mag racing here. I know for sure that you will not get 80hp from an exhaust on a WRX. And yes F/I cars have much more potential but lets be realistic here:wtf:
Kooldino sounds like he is right on point here. That dyno sounds like it needs re callibrating. And the way Dana is adding up the #'s cannot be done as well. If you have an exhaust yielding an additional 10whp and an intake yielding an additional 10whp when combined you wil probably get 12-14whp max not 20.

Agreed

Please someone post the dyno results! I'm sceptical but like someone said before if I get half of that I would be thrilled!
80 hp? get real.. every wrx turbo back dyno I have seen has not even put it over 200 wheel hp.... seeing as how it has 162-165 to the wheels stock, that is only about 16.. I have a magazine (which I cant find right nowJDM Sam said:
) that tests 10 different turbo backs for the wrx.. only 3 put it over 200 whp... peak hp gain of about 20 hp is the highest you will get.. sure there are points on the dyno where you get a little more than that, but nothing even remotly close to 80 hp.....ok I found the mag... it is the may 2003 issue of turbo mag...
I stand corrected.. in all of the tested turbo backs,, each gained anywhere from 50-65 hp at 3500 rpms... however, the boost was raised to 16.5 psi, ,from the stock 12... the highest peak HP was the kakimoto GT, it gave the wrx 203.8 HP....

Ok people, lets not start a flame war here. Let the gentleman show us the dyno sheet. Next, Mags are great for info, but look at all the big ones, (SCI, HCI, Motor trend) they all rated, and judged the MSP differently. What is written cannot be taken as the tuner gospel.
I can truly believe that with the mods this guy has, and with proper "tuning" of the complete system, 200 whp is not hard to reach. I dont have the compressor mapping for our turbo, but have seen that other turbos of comprable size efficient up to 16 PSI. maybe all our tubo needed was to be able to breath.
I understand everyone sceptisizm (sp), but let the guy have a chance to show us the Dyno.
also, Joe is right, I have seen my car steady hold 5 psi, and peak to the 7 in higher gears. so there is a 4 psi (remember, most mfrs will give highest numbers consistanly achieved to sell. Just like with the lower end ampliphier's 1000 watts peak, its actually 300 RMS. )

I hear ya, but my point was to be generous and still show how much of a stretch 77whp was.

Amen, brother.
No we have a WRX and it peaks at 14+psi stock
Perf the car is running 2psi more boost, an intake and exhaust......77whp what?:wtf:
Damn
This is one active thread and no one has gone crazy and turned the torches on. Man this has to be a first. Could it be that us MSP pilots have gotten "Civil?"
Joe Im with you I hope this s*** is for real cause I would dig that level of power with reversable mods if something horrific happen.
Any who I guess the real test will be on the track. Dyno's are cool but track times are better.
