Going for more horsepower and revs than torque?

 

Post your info in this thread.

Oh no going to take your #1 spot
ZZP doesn't count as their links are broken.

 

**** i can't find my other dyno sheet...i have one for 311whp and the other is 296whp i think. all three were at different dynos..hmm its gota be in a box somewhere.



i dont like this one cuz my tq was higher than the hp...
i thought it was weird.. it was 20* outside

 

Nitrous?

What's with the spazmatic torque curve?

 

no nos..
like i said i didnt like this session..
i didnt think the dyno was calibrated right.

i blew the hg wen i sprayed it...150 shot FTW

 

2.4 or 2.0? Off nitrous I've never seen a sc'd ecotec make almost peak Trq at 2200 rpm.

From my own experience, fuel and timing play a huge role in how smooth your graph ends up looking. How well your head/cams flow plays a big role too; but that's just icing on the cake.

Something very peculiar about your graph to say the least.

 

2.0 lsj..
long tube header
3" catless exhaust
ported blower
ported head
pprted ls4
ported intake manifold
custom diamond pistons..
.005 ring gap
zzp rods
cometic. 027 hg
arp head studs
zzp NBs
fidenza flywheel
stage 4 clutch
E85
60's ( i know i know..my idc is like 95-110% at 7250

i know Im missing something

i built the engine and did the tuning.

 

Nasty! Need to go change my drawers. Lol

 

lol thanks..
i took a huge chance with the small ring gap..Im kinda scared to see wat can happen after talkin to mrb about it lol..

 

Nice! Keep us posted

 

Yes sir!

The S1 cams will still provide a fairly decent torque curve, but the extra power up top should be nice.

This.

Almost looks like an LNF graph....

The horsepower peak too early as well.

 

It's been over 2 years. You think someone would have been able to do it...

And this should be enough.

Ding Ding Ding.

 

Poor injectors. There should be a law against beating 60's that hard.

 

If I wasn't stuck on mo...

 

Even if the links worked, Tim's car should be in the le5 section.

 

i plan to dyno my car this month...the problem is that i ca. only get E70 right now...so i think it will be low

 

I wouldn't be so sure. Depends on the place you get your e from. Find a "blend at the pump" station if you can.
Stations where it comes already blended can legally use "any hydrocarbon in the same flash (flammability) range as gasoline. Which means they can use the leftover junk gas as the 30%
Blend-at-pump stations mix it right there with 87.

Quality e70 "should" still be able to give you nearly max power depending how hard you push the tune.

 

hmm Oki never knew that...well i think Im pushing it really hard. Im sure a better tuner can do more.

 

the graph is in DIN. not sae, or std.

there is some serious tune issues.

im actually going to call bs on the whole thing.

 

what does din mean

 

Not to mention the graph does not show an LSJ's powerband....

That's def an LNF's graph. Unless the tune or dyno is that screwed up....

 

like i said that session was fucked up...i posted it to show that i have been on a dyno...that's y ive never thrown around dyno numbers before..
there is to many contributing factors with it..that y i save it for the track...

and to be totally honest.. I'm the only cobalt over here that is moding so ive never seen one actualy run...Im basikly on my own over here...i think the closes guys r in the LA area..

 

Rofl, didn't realize you were only in modesto....got family in Sacramento and farther north.
Broke the car in driving up there lol


You never see other cobalts go down the track?

 

i know of 2 others but the r dds and basikly stock...
