Well guys i dynoed the car sat and my #s were 285.8 RWHP and 291.1 RWTQ, Horsepower came at 5900 and tq was flat from 3700 to 5000 where it started to decline and fell below 250 at 6000. I figured i would make a little more Power than this. The car seems to be fine. I do have a few questions though. On the dyno the car ran up to about 5200 and paused and then went on till i stoped. the graph shows nothing about it happening. Also How could i tell if the transmission is slipping? My Before cam #s were 254 Hp 299.7 TQ, Hp came at 5200 and tq was at 3600 and went down wasnt flat like it is now. Any help you guys have or does this sound normal. With all i have i should have made more than 254 before the cam i think.

My total mods are Mac midlength headers, hooker catback, Precision indestires vigilante 2800 converter, 224/230 Comp cam, 1.6 Roller Rockers, Ion at Madz28 did my tune,

Thanks cal

 

Sounds kinda low, even if you didn't port your heads, it should still be making more power than that.

 

i made more than that with just my mac's and the rest of my mods in sig

 

I'm makin 17 more hp than you and all I have is boltons.

 

Yes guys i know it is low, Does anyone have any idea why or whould a slipping tranny cause this. The only reason i bring up the tranny is that it doesnt always like to change gears at WOT. I am very discusted with this.

Please anything for me to check?

thanks cal

 

Check over ignition and fuel systems.

Plugs, wires, coil, OPTI.

Fuel pressure, fitler.

If all else fails get a good shop to scan the car.

 

Yea i checked it before the cam install and it was fine ill check it again. I dont know but the AFR during the run was really good around 12.5 the whole way through.

what kind of #s are you putting down cause we have almost the same set up? except for the type of headers and the TB.

thanks cal

 

No dyno numbers yet!

I do have some track times tho.

Went 2 weekends ago (after OPTI install) and ran a 12.9 @ 110 w/ 2.05 60' on street tires and thats with my high rpm miss. (5700-6200)

Any times yet?

 

not yet but i bet there not that low

 

Get all the bugs worked out and that time shouldn't be a problem for ya.

You definately have some power hiding somewhere. I think when you find the problem you should put down in the area of 320-330 rwhp. (A4)

 

man i hope so.

Any one have anything for me to try or look at, could it be the rockers? fuel seems to be ok it stays around 12.5 the whole way just a little stumble around 5200?

thanks cal

 

When you adjusted the rockers...did you adjust them with the car warm or was it cold.....you may have over tightened them and that's why you are losing some power...

 

The car was cold for the most part i ran for just a min or two. We went 1/2 turn past 0 lash. That is right isnt it

 

Anyone elese? Should i re adjust the RR and see if that does anything?

cal

 

well the lifters wasn't fully pumped up......i would try readjusting them after a quick drive around the block and see what happens....chances are that they are too tight...
