dyno numbers

[LT4hitsthespot]

Just had my car dyno'd today. Was wondering what RW numbers others are getting from their LT4s.

292RWHP completely stock. Vette doctors said mine was one of the lowest ones they have seen. I was having some issues with the O2 sensors when i did the run. To be honest though, it would have only gain a few horse power if it were running 100% that day. I ran a 12.9@110mph when i first bought that car a year before.

What were the numbers on yours?

298 RWHWP, 305 Torque

306 RW HP. The few mods i have are 160 thermostat, K&N air filter, and mufflers removed. John

Those numbers are very acceptable for a stock LT4. With a good launch and shifting you can run a 12.x time at or near 110mph in cool weather.

PE exhaust

CK racing,

Were your dyno numbers before or after you had the PE mufflers
on there? I'd think your numbers with the PE mufflers would
be around 305 rwhp on the LT4.

It was before the installation of the Power Effects cat back. At the time of the dyno pull I was having issues with O2 sensors, coil and slightly clogged cat coverters and a slipping clutch. So I was really surprise to see it pull 292hp and 304 torq. I think my opti is going bad now. I'd like to replace it and then put it through the dyno again.
