My car with the B1 peaks at 6200 and stays there until the limiter.

 

sorry i missed the point on the SLP LT but i would have to lead into the tune of the PCM get it on a wide band and see what the A/F ratio is

I predicted changing to LT headers would get me 10rwhp, and cats are like 5-8, so I was pretty close with it going up 15rwhp from making this change.

I have almost the same mods as you:
ARE STAGE II HEADS
B1 cam
FLP Headers no cats
Borla Catback
LS6 intake
Ported throttle body
ASP Pulley
ED Wright PCM
Stock clutch (it has not slipped yet)
4.10 gears

I have been to two different dyno's. The first time was with 3.42 gears and my car pulled 388rwhp - air fuel was 13.3 no autotap this time. Then after my 4.10's were installed I pulled 383rwhp - autotap showed all is well. Timing was 25+. I did have nock retard of between .5 & 3 degrees but it disappeared after 5Krpm's. Most of the retard was around 3.5 to 4Krpm's then it gradually went away.

I don't race the car so I have no track times either. After 1,500 miles I broke a valvespring on Saturday (K-Motion K-750's). Know I don't know what to do because I was told that the Comp 918's won't fit on the ARE Heads - 2.055 1.60 valves.

Maybe the ARE heads don't work well with the B1 cam.</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Imteresting, those mods are nearly identical to mine (even stock clutch!). I have doublesprings (from ARE) and shortened pushrods, so Im not sure what to tell you on the springs.

Where did you dyno? what bothers me most is that the car showed 373rwhp before the heads, and now with heads and LT headers Im only at 385.

I always suggest people buy heads/cam from the same place for that reason. If you go and talk to ARE they will blame the MTI cam. If you talk to MTI they will blame the ARE heads. If you have both parts from one shop its harder for them to come up with excuses. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

 

I used:
www.alteredatmosphere for the first dyno
www.woodbridgedynotech for the second dyno

What bothers me the most is that Fireball (lives in the same area) has a B1 with stock heads on his car and pulled 380rwhp through a 9 inch rear with 4.71 gears with MAC headers. So I paid $2,300 + $875 for install for 3rwhp.

I try not to focus too much on dyno numbers but this is crazy. MTI uses the same size valves on there Stage II heads (2.055 x 1.60). I don't know why ARE Heads would not work but MTI's would. Maybe the way they are ported is different. I don't know enough about head porting to make an educated guess.

'Los

 

Mine was not dyno tuned by ED. Ed was told what mods I have and he did a custom tune for me. I know that is not the best way to do it but that is what was done.

I think ezss and I used the same shop for the install/parts so I bet that is how his was done too.

 

Intake: The intake runners were opened up as well as the throttle inlet.

Ed wright: ARE LS1 said, it was sent in based on my mods, not dyno tuned. Timing and AFs look very good though.

My clutch is not slipping. Is it possible that it is slipping ever so slightly and I don't know it????

My AF ratio is 13.3. This was done with a wideband hooked into my tailpipe. I had offroad pipes on so a misreading caused by interfearance with the cats was not an issue. I realize that the shop should insert the wideband sensor up by the header. Should I wideband test it again?

 

PLEASE put a stock LS6 intake on the car and redyno. Your torque loss and HP low sounds EXACTLY like what Terryble lost when he ported his.
Cheers,
Chris

I emailed Terry, and described what was done to the intake, and he thinks it is unlikely that that is causing power loss, but we will check to be sure.

 

Well I blew my clutch out last night, so I guess that will be first on the list of things to try. It grabs ok in the middle of first gear, and thats about it.
