My buddy (who owns an 03 wrx) was telling me that there are a few different types of re-flash programs for his car...is the same true for the evo...if so who rates best????

 

I had a different such experience. Both with my car and a 3000GT VR-4 that is in the shop right now, you will be able to hear the stock BOV better with just a cone filter upgrade. All he had (the VR-4 guy) was just a filter and I have the Injen unit which is a new snorkel. I later got a Type S with the intercooler hard pipe kit and volume increased dramatically and I do not vent to atmosphere. True the GReddy is louder then the stock and it has its signature whistle, but the sound will come through the open filter. Its really a shame the EVO hard pipe kits I've seen are 700-1000. For 2G Eclipse its like 100-200.

 

I would recommend the RMR intake that will be released next week !

 

Shiv, I had it dyno'ed at XS Engineering. The baseline was 220 whp, with the intake and downpipe it was 249 and then 279 with the ECU reflash. Their dyno is down right now, but Rhys Millen and the boys are guesstimating another 20 hp to come from the exhaust (the exhaust alone would be about 12 hp, but coupled with the ECU flash, it should account for the added 8). Hence, about 300 whp. Once XS is up and running, I will get over there and post the sheets. I am not trying to show anyone up (ie with big fake dyno numbers). I just want people to get a realistic idea of what kind of mods do what.

BTW Shiv, what would 300 whp translate to in bhp (ie crank hp)??
I am thinking about 350...

 

Chris in HB: You should be able to calculate crank HP through drivetrain loss which I've heard is around 23% (IIRC). THen do the old cross multiply where you have 77% over 100% (drivetrain efficiency over crank efficiancy) and cross multiply it with 300 over x, which would be wheel hp over crank hp (x). THen divide 77x into the number and, by my calculations, you get roughly 389hp. I hope I remembered the math correctly, it's been a long time.


GPTourer: I'm guessing the Buschur Racing upper hardpipe kit is around 300 bucks. Of course, you either have to relocate your battery or get a smaller one, but that's a good upgrade too. When Buschur releases their lower IC piping kit, I'm guessing that will be reasonable too.

 

If 389 is the estimate, that would make sense. I blew away an '03 Cobra which is rated at 390 bhp.

Thanks for the heads-up. I think I'll just tell people it's stock...

 

I think payment for my math should be a ride in your car. I'm in orange county (Corona Del Mar) almost every Thursday : ) j/k (unless of course you want to )

Um, I bet that Cobra driver was surprised, huh?

 

That's grossly optimistic. The DTS dyno at XS Engineering (edited) is calibrated to read even higher than Dynojets (the previous record holder for big numbers). There's a recent story in Turbo magazine comparing several different dynos with the same car on the same day. It was the most optimistic of the lot by a significant margin.

Recently, a heavily modified EVO (running a GT 28/35 turbo, remap, full exhaust, cams, etc,.) which dyno'd at ~380 wheel hp at Brainstorm later dyno'd at ~280 wheel hp on our in-house dyno. That's how different two dynos can read.

Just for a reality check, 400bhp Porsche 911 Turbos puts down 300-300 wheel hp on our dyno And the new water cooled Porsche Turbos have put down as much as 345 wheel hp on our dyno.... stock!

there is a meet tomorrow in Tustin, 3020 El Camino Real near the In-N-Out, around 11:30 am

 

Shiv,

I had my car dyno'ed at XS Engineering. I don't believe their dyno is that optimistic. Regardless, the net whp gain was approx. 80 with the mods. Going by the Mitsu factory bhp, that would mean about 350 bhp, which was sort of my target.

Chris

 

Actually, I mean to say XS Engineering, not Brainstorm (although they both have the same type of dyno). So yes, they both read very high. Higher than Dynojets, from what I've seen and as illustrated in the Turbo mag tech story.

Shiv

 

Shiv,

(Last time, I promise)

Regardless of the baseline (180-220), the net 80 whp is a very worthwhile gain in my book for a $2300 outlay. My last car was an S2000 and $2300 might have gained me 5-6 hp with possibly a 2 hp loss somewhere before VTEC. So you can understand my pleasure.

Thanks for all of the responses. I read about a lot of your work in SCC.

 

Chris that is a good point and why the EVO is so great. Guys with 350Z's wish they could get this amount of HP from their $$$$.

 

Altered Atmosphere uses a Dynojet and a base Evo was doing mid 220's....

Shiv you were there

Actually, stock EVOs were doing anywhere from a low of 216 to a high of 248 wheel hp on Altered Atmosphere's dyno. And the dyno at XS reads even higher than that. My point is that unless you dyno'd your car stock on that dyno, you do not know how much your particular car gained. And the gains should be described by % gain over stock and not a fixed hp number gain. This is because 1hp on one dyno can be significantly larger (or smaller) than 1hp on another dyno (ie. a 50hp gains on a DTS dyno may only be a 35hp gain on a Dyno Dynamics dyno). Read that Turbo mag story and see for yourself

Cheers,
