Thread: 430+ whp on an m90?

pump gas power or bust.

Your gas mileage also goes to dick when you run it.

On an open loop tune you can get pretty decent mileage on E85 by running a bit leaner and jacking up the timing.

Yeah, that's an awesome ratio right there per density....very practical.

Gotta pay to play. Once you get to a certain mod level with a car there arent really any other mods you can do without spending big money. Also, for someone such as yourself that apparently tunes cars it should be no problem going E85. Swap in a pump gas tune to daily and throw your e85 tune back on before the track... its a pretty simple process. ****, for that matter you can have someone buy an extra PCM and tune one for pump and one for E85... takes 3.3 minutes to swap it out.

Example: Theres not much left I can do to my turbo car besides some beefcake heads for daily consistent performance... except e85. Everything Ive done on my own car has been pump gas and I dont even daily drive it. I need a monster fuel setup but all in all in will be worth it when I gain 50-75+ whp out of it... and not to mention running something like E85 or race gas is more forgiving when you have mechanical or electrical errors on your car that would otherwise chunk a piston. Its going to end up costing me maybe $300 in fueling mods on my car to go E85 after I sold my Racetronix pump.

Anyway, my point was that someone said 350+ whp is hard without spending big money... and that was my point. A buddies setup that Ive worked on and tuned hit 350+ pretty easily and still has room to grow after we fix a few things: better valve springs and a better fuel pump. Of course, with a stock trans he isnt going to put down any amazing track times but thats next on his list of things to get rid of.

E85 is pump gas

I used to live in a town where there was 4 stations:
Dubuque, Iowa
Population (2009)
- City 57,222
- Density 2,178.2/sq mi (841.1/km2)
- Metro 91,765

Now the nearest station is 19 miles away from me. I still daily drive E85 and have a 70 mile commute each day.


Go to:
Ethanol Retailers
And pull up the locations nearest to your zip.

"E85 makes your gas mileage go to ****"
Obviously your not using the type of Octane for the proper benefits. It is pump gas 105 octane that has been proven to make more power on boosted setups than 110 leaded fuel. Not only can you run more boost, but more timing. The AFR range of E85 to make the most power is also very broad. It can be run lean 12.5+ and not knock, it can be run rich10.5- and still makes power. At $2-2.20 a gallon, I say **** all the nay sayers.

there are diminishing gains with e85, but the more fuel you can dump in the more power you can make. think 7.0:1 and still not at peak power yet.

i had a racetronix pump, rewire, and 65# motrons ready to go in my car a while back. i decided against it because i didnt want to have to make sure i made it to a station with e85. i like pulling over whenever i want. i always ran 92/93, its hit and miss in WI for a station with 93. i wasnt going for max power since i DD'd my car and the whole goal was to make it entertaining for me to drive each time i got in it. never even took it to the track.

Yeah and that was me who said that. I said it as a general statement that people barely break 350whp with a m90. Which is probably a little too fair given the Highest HP Cam Chart. They only list the top 5 numbers for each cam, and the only cam to have more than 350whp on the whole chart is the XPZ cam. So I'd say it's pretty fair to say most people struggle to break 350whp.

350whp on the whole chart is the XPZ cam.

Besides the fact the the chart is outdated there are other cams that have hit 350+. We did 344whp non-intercooled with an L26, S1X cam + 105# springs, N*, 65# injectors, fuel pump rewire, and E85.

My point was, that what you've done is good, above average. Usually people will struggle to break 350whp in a decent cam, IC, higher compression or heads setup.

And the HP cam chart was last updated 3 days ago:

Forgot that DBTK2 had his cam chart stickied instead.
