Thread: dynoed and tuned a 99 m6 t/a

Car is a 99 t/a m6 ls1

mods
long tubes
edlebrock muffler
ls6 intake
slp lid


has no cam
853 heads
base 327 337
tuned 356 360

This was in 100 degree shop conditions,and after 10 pulls,no cool downs.

Total timing ended up being in the 27 degree range,no kr
a/f was 12.7 flat line.

Looks about right for an m6.

LS1 baby!

what was scary and a reminder about modding cars,this thing was LEAN with a ton of KR..a/f was 14.0 at wot and spikes of 14.9..Had 6 degrees of KR also.All with just simple bolt ons.

I would say if this car had 241s or 243s it would make another 10 or 15.Im going to do a pull in the morning and see what it picks after it being cool.

This was also on a dynojet 248 h not the happiest of dynos.

damn dude those are bad ass numbers for no cam!!! holy crap

thanks cesar.I thought they were pretty good myself.

def man especially for a hot day and crap heads

im just digging the improvemnet with just tuning,on such a mild combo.

yeah hopefully he didn't pound on it too with the stock tune lol that is pretty damn lean
