So thanks to Eric From ForceFed for taking time out on short notice to dyno me and here are the results.

Last year I made 481hp @ 28.0psi and my first pull I had bad clutch slip at 6k but on my 2nd I was able to make 478hp @ 25psi!! I was really happy with this because of how much flow the port job I did myself and the Stg2 cam I added to what I made last year. After a couple more pulls and some tuning (there's more left) we got some new numbers!!

Mods are: 2010 Cobalt SS LNF stock bottom end, ported head, stg2 cams, 7163 efr, E30 + meth, DP, exhaust, IC, IC pipes, CAI, HP Tuned at 27.3psi, Turbosmart dual port actuator 23psi and stg4 clutch stock disc on a 4.05 trans

Glory Pull up to 7500rpm




3rd pull




So I didn't make what I set out to but did beat my min goal I had set. So for later this year I'll head back with more E new clutch and more boost to see what numbers I can end up with!!

 

I forgot to add all the pulls were done in 4th. After the 1st pull where we started at 3k and smoked the clutch the rest were all done at 4 to 4.5k. I'm happy with the torque numbers when hitting the pull so late

 

Dam very nice numbers

 

Thanks! It's sad I had to leave when knowing if the clutch would have held it had so much more to offer

 

ugly wheels

 

And tires!! Why do you think 3rd gear can't hold!!

 

Eric said that last pull torque steered all over the dyno he had to 2 hand the bitch!

 

Dmn dude 511 thats awesome! Out if a little 2.0l stock bottom end to right? Thats impressive dude.

 

Thanks!! Yea still stock LNF 2.0L. More to come next time after I figure out my clutch situation

 

slow :P



Nice work Kev. looks like fun haha

 

Nice!

 

Nice man congrats great numbers with a slipping clutch!

 

Sick numbers, gratz! Now time to break some hearts!

 

Thanks it is slow.

Thanks!!

She's pretty useless right now 1st to 3rd spins and 4th slips 😢

 

Lol well aren't you in a pickle, easy fix get a new clutch and install better tires

 

I have better tires. Wonder if they can hold this power. I didn't have any slip logging in 4th

 

So SAE corrected, it's around 491whp? Nice work Kevin

just busting your *****

 

Well we had to work for that! Had to do higher rpm pulls to keep the clutch from melting. Prob one of the reasons why it was lower boost too

 

Nice numbers Kev

 

Awesome man!

 

Thanks guys! I'm gonna fix some things then get some better numbers!!

 

The numbers are definitely impressive but what I'm really impressed with is that monster powerband! Add some wings and you'll fly. Lol I mean numbers are great to brag about but when u have a monster powerband mountain backing it up, there's nothing else that needs to be said.

 

Thanks. It is very nice pulls hard all the way to redline. I put my NT01s back in and it's a night and day difference!! I'll be able to tune better now without constant wheelspin so when I get my clutch upgraded I'll crank up the boost and let her eat!!
