Thread: 2.0 VE dyno testing

OK.. so the 30 whp came from The ITB's Basically!!!!
Its what you are saying!!!

Almost 100%. I heard of this through the grapevine as I was stuck working while this went down. The ITB's are the truth!

wow

ECU? aem standalone?

Yes..

Both graphs were the exact same setup besides the intake manifolds.

Thought it was quite clear in the initial post.

86mm 12.5:1 CP pistons
Stock rods
4cw crank
Head was ported by me
Motor was assembled by me, rings gapped for nitrous.
Cams are not big by any means.
ASP 4-2-1 budget header
1st graph is with custom manifold with large TB
2nd is the next day after bolting on ITB's and AEM.

It's not surprising by any means, this test was done on a stock bottom end VE With N1 cams months ago and went from 205whp to 230whp.

I told you guys in PR months ago, stop wasting time with the N1 runner/excessive plenum.

Even if it's not ITB's, real power can be had with a real custom plenum manifold with a large enough TB and the right cam.

@ SR20FTiR,

what size tb, what size itbs, if you dont mind?

thanks

peace

Take the size velocity stack being used and multiply it by 2 to give the TB needed to properly supply all 4 cyclinders.

In the case of my last custom manifold with 52mm stacks, a 104mm TB would be needed.

The ITBs are pretty small, under 52mm.

OK
Most guys here use regular VE runners with the Xcessive plenum not the N1 runners with the 45deg elbow and Q45TB I know its not the best but good numbers have been achieved for example Pito's 2.0l setup that makes now 228whp @ 158ft/lbs on N1 cams and regular SR16 pistons on a stock unported head with a Big tube Tri y converted to 4-1
Believe me most of the guys here including me cant afford the ITB's jejeje
Great gains on ITB's FTW!!!
Good job!!
