Scottie-GNZ Posted November 17, 2000 Share Posted November 17, 2000 Any reference I make to HP is always at the wheels based on a formula that uses the ET, MPH and weight of the car. In the case of my L28T, it was 13.02 @ 110.97mph and 2760lbs = 287hp at the wheels. It was more like 295hp because the ET was badly affected by wheelspin. The drag racers out there will recognize that the ET is slow for the MPH, but MPH is the true HP indicator. BTW, the other car in the picture ran a stock N/A block with a P90 head (about 8.5:1 c.r.), t3/t04 hybrid turbo, Spearco I/C, stock DP/2.5" exhaust and a Jim Wolf setup. The car ran 12.32 @ 114.32 with 22psi boost . I definitely do not recommend this. It was done at the track with race gas (there's that octane thing again) and the Spearco was key. The formula spit out 310hp (car is much lighter than mine) and we believe we are now at 350hp with a freshened turbo block (stock pistons), SDS, larger injectors and better DP/exhaust. My main point is that big HP numbers can be achieved with a higher than normal c.r. and relatively stock block. Whats important to understand though is that those numbers are only achievable when at the track with race gas (110+octane), higher fuel pressure and lots of boost. What you get on pump will be less but if you become adept at programming the SDS fuel, ignition and retard curves and additional retarding when knock is sensed, you can do fine on the street. ------------------ Scottie 71 240GN-Z http://www.mindspring.com/~vscott911/gnz.html Quote Link to comment Share on other sites More sharing options...
