Thread: 88mm on a budget!! (Not on budget anymore!!!) New Dyno!!

The new build results!!!

Setup:
88mm 12.5:1 JE Pistons Chinese Ebay H-Beam rods
Cometic .27in 88.5 bore head gasket
Slightly ported SR20VE head with supertch springs stock retainers
Kelford 184-C IN N1 EX cam combo!!
P11 Xcessive plenum kit with 45deg elbow ported to remove reverse taper!!
Custom 4-1 stepped header with megaphone and reverse cone
Tuned on 93 sunoco pump gas By Me!!

Very nice... Would like to see what gains it can get from E85 and or meth.

I can tell you M5 would be 20-25whp more for sure and we dont have E85 on the pump only 5gal E85R and its way to expensive and these is a true street car!!

El Colo made 268 on a setup similar to these one on M5

Wow awesome results. Great job!!!

Its really crazy how far all of our NA builds and even just our expectations have come in just the past 5-6 years : )

Good job Payu....
Awesome numbers
I really want a 88mm built :P

What are the SAE numbers?

So from looking at your other charts in this thread their very close. I see that you've switched from your custom intake manifold to the Excessive. Do you have any overlay of the two, I'm curious.

Also on your last chart didn't you find the n1 intake cam was better than the 184c on this motor? What made you go back to the kelford intake..?

Payu which injectors are you using?

At what point does it become necessary to switch out the 333cc for 370cc?

On the last Dyno graph it had the 184C-IN cam it only made a couple of whp extra from 7000 to redline (Cory) I shitched to the Xcessive manifold for simplicity also for the results Pito had on it!!
With the 4-1 I lost some mid range power activating cams @ 6000 I didnt have time to test lower cam activation
Here its the graph!!
