1990 #2180 Dyno pull - ZR-1 Net Registry Forums

ghlkal · 07-22-2013

If these numbers are accurate, I'm a happy camper

RWHP 337
"corrected for temp/humidity/pressure" = 353

RWTQ 320
"corrected" = 335

(both at a whopping 5500 RPM or so)

They had some issues loading it on the dyno and by the time they were ready, the car was already pretty hot. I tried to convince him that redline was a little higher too ...

There was only one useful pull, and here are the sheets

The techs hadn't seen an LT5 in person, although several knew about it.

The only "mods" I have are Corsa exhaust and SLP claw intake. The engine runs great after I replaced the fuel injectors.

OK, gurus ... let me know your thoughts. Is this thing really 400HP at the crank?

That's the same type of dyno (at least the website on the printout) that I ran my '92 on. The operator took my LT5 to the same rpm before shutdown.

Good numbers. With headers and a chip I would guess you will hit 370whp no problem!

Time to get headers and a ported top end....

Damn, the girls (at Mercruiser) built you a strong one. I had to do headers, K&N, exhaust and a chip to get to 353 RWHP on my 90.
