Dyno 13B peripheral video

Just ran the EX IMSA RX7 Peripheral 13B on the dyno, and here is a link to
the video.
Unfortunately the ignition cut out at 6800 rpm, and we were not able to fix
it at the dyno shop.
We will be back next week we a proven ignition system.

Wow the sound is really misleading. I thought it had reved way past 6800rpm. Still sounds great though.
You've made awesome progress on the car.
Next I want to see some in car video at the track.

WOW! Sounds incredible. I LOVE that "BRAP BRAP BRAP" of those. How "reliable" (ha) is pp? Would a good bridge be better for a street/race setup?

Sorry for being off topic, but I need power.

A PP lowers the motors life expectancy worse than a BP

Go with a bridgeport or half bridgeport for a street/race setup

I'm not going to get into anouther debate about wich is more reliable. But you are completely wrong. CJ

I have to agree with CJ on this one. 4RR: how many modified engines have you personally run? Other than your vast knowledge of how to steal pics of other peoples work and claim it as yours?

I have been road racing since 1995. I ran a 12A peripheral port motor from 1997 thru 2003, and it never had to come out of the car all those years. I built a new 13B one this year because the old one was getting tired and I wanted more power and torque from the larger 13B.
PP motors are more reliable than bridge ported motors. The only reason anyone races a bridge port motor is because either their race rules will not allow peripheral ports or because they can't afford PP.

I have driven my PP motor on the street, and it is not streetable. It will not pull at low street rpms because the PP is timed for high rpm torque only.
