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.

thats sick........
how high can it rev??

 

normally with my drysump 10.5, this time it cut out at 6500.
Benny

 

carb or FI?

open exhaust?

what did the dyno print look like up to 6800?

 

58 genberk carb. at 6400 184hp, so base on my last engine pull I 'm right where I should be to acheive 292hp at the wheels.
Last time we had 182hp at 6400

 

Exhaust 3'' with Borla Mufler (burn in about 3 hours anyway !)

That was absolute music to me ears.
Cant wait to see the full run to 10.5k rpm

 

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?

 

lol, that thing isnt even an rx7 anymore! lol moor sounds amazing, i wish my fc sounded like that

 

Actually I getting more life out of my PP than a brigeport. I have no over heating problem and run a full season on my PP (unless I miss shift !!!).

 

Was that a 5th gear pull?


-Ted

 

No it was a 3rd gear pull.
thx
ben

 

Did I miss the dyno numbers somewhere?
What did it do with the lower redline?


-Ted

 

184hp
Will go to the dyno tomorow morning.
So will post new results

 

Sweet! Can't wait to see it and compare to my little 12a J-bridge with ceramics

What size chokes in the gene berg?

 

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.

 

How did the dynoing turn out benny? Take any video? When will the car be back on the track?

 

here is a link to a 10500rpm pass

 

Uh, am I the only one that doesn't see a link?

 

nope!

he just did it to get our mouths watering!
