this past weekend i got my car dyno'ed.

as a lot of you know GM rated these at 205 at the crank. i collected a lot of heat soak in the first 2 runs.
i was driving it like half an hour and went straight on the dyno. on my 3rd run i let it cool down for like 10 min and made 232 WHP and 205 WTQ
i was pretty surprised.
just a little more proof of how underrated these cars are.

now what are the corrected numbers?

i think those were the corrected numbers, it was at race lab on a dyno jet, he told me he had all the info of the elevation, humidity, etc already plugged in and this was to the wheels.

that would mean you are at around 250 give or take crank HP. Not bashing but that seems really high.

ohh ok, i didnt understand what corrected mean then.
well honestly i was a bit surprised. but they dyno a BUNCH of cars there, most ppl leave happy and are ok with the results. my friend has a turbo LSJ running hahn kit with a s20g turbo on 18 psi
and did like 330-340 WHP. i mean, just something to compare it to. i hope its accurate lol.

i had intake, injectors, 2.9 gmpp manifold, downpipe, catback and tune when i made 239. i know diff places are going to be different numbers, just saying though for reference

yea i get you. imma get a zzp stage 3 soon with 2.8 and all supporting mods.
imma dyno it there after again see what my numbers look like. i dont rely on just numbers, i know a lot of dyno's are different but at least to have an estimate at where i am.

yep believe it or not, we had a dyno day here last summer and I saw 2 stock* (* = so the owners think anyway) IRL's dyno in the 230's WHP STOCK*!! The lowest stock dyno I've seen on an LSJ is 217 WHP

rallycobalt06

i need to dyno there then, i need an ego boost.

HA! I have ZZP BRFPR, TVS, 80's, header, full exhaust, all the cooling mods except meth, trifecta dyno tune, and I was at 312 WHP on the same dyno so it seems to be about right IMO.

rallycobalt06

oh.... i bet that broke your heart a bit. all those mods and only 312whp. ouch.

MMM a little but not really. It is a very safe tune with no meth and no corn. I could pull more out of it with E, meth, or just a more aggressive tune. The horsepower is still increasing when the engine hits rev limiter (7200 rpm) so valve springs and balance shafts to allow me to rev higher would pull some more ponies out of it too.
