D-Rob's 2nd Dyno Bye Bye Stock w/numbers
 
Went back to the dyno last Saturday. This time with a Injen Intake, Bad Mab Header, a Corsa Performance Touring Exhaust and some 42# Injectors.

Tuning was done by Arthur at Trackmasters Dyno in Huntsville, AL. As usual with me, I'll make a video lol. I was honestly disappointed in the peak gains, which is dumb in a sense, because I'm am most certainly making at or above stage 2 numbers on the stock pulley. I just thought I'd see more over my stock dyno peak.

Nevertheless that doesn't really matter, under the curve the gains were huge, and the car (after the tune) is so much faster it's beyond description. It's faster everywhere, it feels like I raised the boost faster, my brakes are begging for mercy after a 3 second wot faster, and that, is real nice. :twothumbs

Cooling mods will be in tow, because at the end after placing the fan on the supercharger for less than 8 minutes, I pulled out 5 more hp on the last run. 25 degrees total timing, 7250rpm limit, abuse management turned off.

Final number 236hp (235.99, I rounded up) & 204lb/ft.

Over 20hp & 48lb/ft under the curve.

Damn that is tight and thats only intake and exhaust right

WSox33 05-16-2011 06:57 PM

Thats a nice torque curve.

1AJeremyD 05-16-2011 06:57 PM

Great number increase on just those mods! Do you plan on doing a pulley down at some point?

No sir, header, 42# injectors and a tune as well.

D_Rob 05-16-2011 07:10 PM

Thanks WSox33!

Yes I do. I want to do cooling next. I don't feel it heat soak, but on the dyno it was visible in the results, cooling the intake air would help me a lot.

1AJeremyD 05-16-2011 07:17 PM

I pretty much had the same idea as you with going about modding. Leaving the pulley last and doing everything else first (intake, exhaust, injectors, cool and then pulley down if i feel like it later)

wow!!! thats great!! how much did it cost to get that tuning?

He charges $350. Higher than Nick at BYT but I can't drive all the way to NEPA lol.

MaGNuM16 05-18-2011 10:02 PM

what kind of dyno? i dynoed my car on a mustang awd dyno with stage 2 kit , megan exhaust and intake and i only hit 185whp. is your 236 crank hp or whp? either my cars f*cked or the dyno i used is at 25% lose from crank to wheels .... :bye:

09sscalicobalt 05-18-2011 10:09 PM

haha godamn these numbers make me glad i bought a ss/tc lol sorry guys

Chevycobaltss3 05-18-2011 10:16 PM

lol. numbers are okish..... Not saying anything bad.... And im not promoting myself by no means..... But i am close lol.... Just simply saying im close hahahaha

MaGNuM16 05-18-2011 10:59 PM

im thinking its the dyno cause my buddy when he dynoed his 08 sti whp was 210 and my other buddys 09 evo mr dynoed at 220whp some disguisting drops from crank to whp or the dyno needs to be calibrated . anyone have issues with awd mustang dyno?

murphy0789 05-18-2011 11:05 PM

I dynoed 251 whp on ZZP's mustang dyno but it's not a awd dyno. My mods are 2.9 42#'s ZZP Custom tune I purchased their stage 3 FMIC before I left my intake temps were a little high but nothing dangerous had zero KR.

I don't know why, a bolt on cobalt made 235whp. SS/TC's average within +5 or -10. And bolt on's don't do much for them. Just boost.

LOL. I know right. I keep thinking that more and more as of late. I dunno, considering he will HAVE to fix my tune, I think I'm doing pretty good for stock boost.

Chevycobaltss3 05-19-2011 08:50 PM

Boltons do alot when tuned for them...

Chevycobaltss3 05-19-2011 08:51 PM

235 to me is still low. Because tou could be running tons and tons of timing. Did u check ure ic pump and s.c coolant lines for bubbles.

D_Rob 05-19-2011 08:56 PM

Nope, I didn't check for bubbles. 25 degrees total timing. I expected more given my base number and my setup too.

Chevycobaltss3 05-19-2011 08:59 PM

Yeah how much timing was added throughout the whole map. And he could have leaned u a lil as well.

RooTBeeR 05-19-2011 09:04 PM

looks good, but compared to a GMS2 your tq is lacking a little bit, essentially boost=tq

I was noticing that too man. I got HP and good TQ but a good deal less than with a stage 2 kit. I built boosted Hondas, I didn't have torque, I like it now. Torque is my fwend :twothumbs

Your right I'm sure. Ugh this whole deal is just frustrating.

RooTBeeR 05-19-2011 10:27 PM

still definitely better than stock!
