Supercharged People...Trap Speeds?

[nbilyue]

Hey guys I ran my car for the first time with my supercharger last night and I feel like my trap speeds were a little low. I am going to the dyno in 30 minutes to see what my whp is. I am afraid my TSX cams might me too aggressive and I might be losing boost. Anyone have any ideas? What trap speeds are other supercharged guys getting? Please help!

well the reflash isnt tuned for cams so.... you may be loosing power. Or i could be wrong.

cant wait to see the numbers

what did you trap and your et?

[Whocares05050]

curious as to what your putting down, + what your afr looks like.

[geoscranny84]

well i dont think its the cams...........post up ur Dyno sheet ..when u done!!

[HONDACARE]

have no runs yet to compare, but i think your semi-tuned f/i plus your untuned cams are cruisin for a brusin.

[dil2502]

so what was your trap speed???

[nbilyue]

Trap speed was 100. Only got like two runs in on stock tires and got a 14.1, the best at this track before was a 14.7, i def could have done better with a few more runs. My AFRs are fine. Dynoed at 241whp but i was only at 197whp before so the gain is about right. I just expected the trap to be a little faster.

Sounds like those cams are hurting your numbers. Most that have the S/C with i/h/e are dynoing in the 250-255 whp range.

Didn't you say when you did your N/A dyno that your run was on a Mustang dyno??? If so, that would explain why his runs are alot lower than everybody elses. I don't know why everybody gets so concerned over numbers from a dyno, they prove nothing because they all read different. I like his topic better, what kind of traps and ETs are the other supercharged people running...

[nbilyue]

Yeah I really don't think the cams are hurting anything. My AFRs are fine and I gained 45whp which sounds about right to me. A lot of the guys with 250-260 dynoed with bolt ons at like 205 which was 8whp more than I was with bolt ons. I really do think the dyno i go to reads low over all but like ^ said trap speeds are what really interests me.

your car should be alot faster than 14.1....try taking the cams off and go back to stock cams....

my best trap was at 105 i believe but i couldn't hook up in first or second at all. I think you should definitely be alot higher than 100 mph.

bad launch = high trap

when you spin on street tire you end up with higher traps

This track is a very slow crappy track. It had also been raining all day. Like I said the fastest time I had run at that track before was 14.7 at 96 I think. I would have gotten a better time eventually but it started raining. Also remember I was on stock Michelins and still managed a 2.1 60".

.6 gain on a bad weather day at the track is not bad. Get some better tires and go back on a nice day.... with practice I suspect you will get mid to low 13s easy.

[hockeymutt]

what were your torque numbers?

[nbilyue]

I think you need a real tune. The reflash you have is a very conservative tune for cars with otherwise stock engines. I think you're not taking advantage (perhaps even losing power) of the cams because you don't have a real tune.
