Back to the dyno with the Huron kit - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Went back to the dyno yesterday. Made sure all plug wires were clicked on good. Drove down fine. Made some pulls at 7.5psi to get the fueling dialed in. I thin I finished with 575rwhp/600rwtq @7.5psi @ 17 deg. Turned the wick up on the boost controller and probably made 8-10 pulls in a row without the car being shut off. I would make pull, adjust the boost controller, and make another pull. ECT's were up to 216F (I am usually less than 190F on the street).

By the time I got to 15psi, something funky happened. During the pull I developed a miss but didn't notice it until after the pull. I pulled 655rwhp/725rwtq. The hp peaked at 5200 and stayed flat all the way to 6300 or so.

When I looked at the map readings, I made 15psi at OK tq, but boost fell off to 11.5psi by 6300rpm and the same time boost fell off, my A/F went off the charts rich.

On the next run I felt a low rpm stutter like last time. Called it quits there. When I got home I pulled the MSD wires and three of them had broken/split insulation.

Put new wires on today and no more stumble.

Gonna head back again and see if I can keep them alive for final numbers.

An interesting note...
On 7.5psi my 60-145mph was 6.9 sec
On the 15psi pull (655rwhp/725rwtq) my 60-145mph was 6.4 sec

I doubled the psi, but only gained 0.5 sec in the pull.

Attached is the graph versus one of my old heads/cam pulls (not the highest numbers for the heads/cam as I made 461rwhp/421rwtq, but you can seen the difference in curves pre and post turbo).

Here are the plug wires.

Stock shortblock? Mods? Meth? E85? I got the plug wires they recommend. So far so good

Stock shortblock, 93 + meth

I've been running 93 and meth for a while with a small cam at almost 13psi. Do you have headstuds or a cam? I've been debating on going 15-16psi with e85 and meth.

235/231 .6xx/.6xx 115lsa cam and I do have head studs. My heads were also ported by Advanced Inductions.
