Cam or Stall

**new2dgame** · 02-16-2014, 07:09 PM

ok i have a ls1 with torq v3 cam 3600 stall (loose) ls6 intake ported 241 heads milled 40th stock 242 gears the car only made 368hp to the wheel what did i do wrong?( i was expecting more rwhp)

Have you put on headers? If not that is what is holding you back most likely. I would get some with 1 7/8s primaries and a 3" y-pipe if you haven't done that already. In addition have you done a lid or anything else to the car. Ported 243s will also perform better than 241s. How much port work was done to the 241s?

got a tune?

do you mean 342 gear ratio?

A4's come with 2.73 or 3.23, M6's only came with 3.42 If you are using a 242 then that's the problem I would think.....

HP/TQ numbers are lower on a DYNO with lower gears (such as a 4.10).

At least I believe that's correct.

could have also been on a Mustang dyno

Those numbers don't look too off to me

. He's an auto so his car would be around 300rwhp stock. He basically only listed a cam for a power adder. Ported 241 heads aren't going to give you a big advantage. You need at least 243 or aftermarket to see bigger gains, along with headers and full exhaust.

Need more info on the car and the dyno. Who ported the heads, and what were the flow numbers? Mustang or Dynojet? Who did the tuning? Exhaust?

The HP numbers don't mean all that much, and are even less important with an automatic. You have a setup that should be quicker than most cars putting down 400+ rwhp.

The most important thing here is how the car runs at the track. The combination you have, if tuned properly and if it hooks, would be good for easy 1.7 60's and should run down in the 11's.

Regardless of the gearing (which will affect the torque result), the horsepower result is always the same (provided the numbers are correctly entered into the computer). The horsepower does not change since it is a measure of the "work" (wheel revolutions over time) which is multiplied by the torque to get horsepower. More torque = less wheel rotations/time. They always balance each other out for the purposes of calculating horsepower.

what did your air fuel ratio look like through the run? Do you have the sheet to post up? I agree with FBJ.....quarter mile times will tell you more than dyno numbers. I would however expect those numbers to be a little higher than they are. It could be a bunch of things. I would want to know who did the head work and who did the tune.

Yeah, I agree. Had to think about it a little more. You are correct!
