Subject: Down 100 rwhp . by Try2pas on 2010/8/22 17:01:49 I have an LS3 with a 4L70E trany, 1 5/8 headers, 2 1/2 exhaust, no cats, and aluminum drive lines. The car was set up without the aid of a dyno. I dynoed it the other day and only got 261 rwhp! It should be at least 360 rwhp. What could be wrong? Also the dyno said it was peaking HP at 5500 and the engine is supposed to peak at 5900. It seems to me the car in second is reving a lot but not going. Wouldn't it have to be either engine tune or the trany is slipping or a screwed up dyno? At Spearfish the other day, which is about 3500' high and it was about 80 or 90 degrees, it ran an 1/8th in 9.10. What gives? |
