Inquiring mind wants to know. Is 320 doable on an 05 with a downpipe, cat back, throttle body, wellbro fuel pump, mr bypass valve and a works drop in filter...oh and a dynoflash.

 

Yeah

 

so it still has the cat?

there's no way with just those mods.

 

i'd say probably...with a boost controller...and get rid of the cat

 

I hit a 12.3 with cat back/unleaded race gas and Warrtalon hit a 12.1 with down pipe/test pipe leaded gas. Warrtalon also hit a 12.2 with cat back and unleaded race gas. You will need a boost controller and race gas either unleaded with cat or leaded without the cat. Is your 320 goal BHP (crank) or WHP and on what kind of dyno if WHP?

 

hmm that's a stretch even if you had a straight pipe and boost controller on pump gas...You'd be lucky to break 290.

 

I put down 300 on a mustnag dyno. with 93 octane, tbe,mbc, drop in filter., and a custom dynoflash. And compared with other dynos this one reads much lower.

 

WTF? Where u getting your info from. I Got 280WHP on a dynojet with TB Exhaust, aem intake, MBC 21psi Greddy Type S Bov. NO TUNING! This is on an 03 EVO.

 

dame if you were tuned you would definantly break 300, mines also an 03.

 

When I say BHP this is the mfg way of quoting h.p. Dyno's vary like crazy and whp is not really that important to me. 276 stock bhp...can I get 40plus h.p. without cams? For instance:
Good cat back=10h.p.plus
Good downpipe=5h.p. plus
Air filter=4h.p.
Dynoflash to tye it all together=20h.p.
Maybe 35-40bhp from this?

 

MOST DEF!!!! Its easy to get HP outta our cars!

 

the question is, will your car be done when you hit 320 to the wheels?

add Hallman boost controller, LPI IC pipes, FIC 650 injectors and meth injection plus tune.

You will definitely reach your goal on stock turbo and cams after these mods.

Well, there's no reason to ask about crank horsepower, because none of us can measure it and none of us know the stock crank horsepower. What Mitsu lists is probably not true. Dyno's may vary, but cars on the same dyno don't usually vary, so they are still much more useful than theoretical crank numbers.

Anyway, if all you want is 320 to the crank, then all you need is a tune, because in my estimation, the 05s are already putting out 300bhp. Why do I say this? Because I (and many others) dyno'd 248whp stock on a regular Dynojet that is not known to read exceptionally high or anything. I also ran 13.1 at 104, which indicates my WHP readings are accurate. Hell, the car was probably capable of 105, but that was my only full pass in stock form (5k limiter issues). If you account for 20% drivetrain loss, then 248whp = 310bhp. Some would even say it should be 25% for an AWD car, but I like to keep it conservative at 20%. Even if it was 15% (like a FWD), that equates to 291 bhp. So, if we take a nice, simple average of the two (17.5% loss), you get right around ~300hp. Then, a tune (flash, safc, whatever) will get you 20whp right off the bat, so you're already at 300. The mods you listed, as long as you include a boost controller or boost-controlling flash, would put you more around the lines of 350-360hp, which is right around 300whp when using 17% drivetrain loss.

I dyno'd 282 with cat-back/mbc/mr dv/s-afc. Now, with a downpipe and testpipe, I would assume I'm right around 300whp. On race gas, i hit a 12.1, but more importantly, I hit a 7.7x at 89mph in the 1/8th, which means i was probably close to 340whp...

 

Just make sure you replace the throttle body (????) with an MBC and boost gauge. Also, don't get a downpipe without a cat replacement. For the power you want, ensure that it's a test pipe, otherwise don't count on it.

Do you not want us to answer the topic of this thread? Your text section doesn't match the topic question, so I was going to touch on that next. Do you want to know what the max HP is that can be made on the stock turbo without cams? Does that include any type of gas (e.g. C16), or just pump gas (91 or 93)? Also, if it's just pump gas, then is alky injection ok? What about FMIC, IC piping, tubular manifold, ported o2 housing, and a lightweight battery?

With all these mods on race gas and the proper tuning, I bet you could go over 350whp on the stock cams. I believe I'm very close to this already when using race gas at the track, and I don't have any of the mods listed in the 2nd paragraph...

 

he's asking for 320 WITHOUT a straight pipe OR MBC. You got less than 290 WITH THOSE MODS.
