blackhawk98

Even on motor, you could be pushing the limits on your stock injectors. What % duty cycle did your tuner say the stockers are running at?

blackhawk98

I have no idea man...i will have to ask him...well i hope its the fuel pump

I know my 36#ers are at 75%... I would mention it to him when they swap the pump just to see where they are at if you curious.

blackhawk98

ok...how much power u think im lost? whats ur set up on motor?

if you put down 320 then I would have to say your down at least 80 hp. H/C and the LS6 intake should be around 400.

Do you have your dyno sheet?

blackhawk98

No.... im suppose to pick my car up this week when he finishes...u think i could run low sevens in th 8th??

With that verter you got, there is no reason why you cant get a 60' in the low 1.5's and even a high 1.4's... You get that down you have a very good shot at it.. Its all in your 60'.

blackhawk98

thats what i wanted to hear...i jus need some slicks my mts dr could barely hold last time with the power loss...thanks man this car has been a pain in the ***...what did you do to lighten your car?

What size MT DR's?? I have cut 1.45 60' on a stock 16" wheel with a 255/50/16 MT DR.. So, they can hook, just lower the pressure to around ~18 and you set.

That not that light.. Its light I suppose seeing it has a cage, 9" and a heavy *** moser drive shaft.

blackhawk98

I have 17x9 1/2 rims i lowered the pressure to 16 lbs is that to low

It shouldnt be too low.. Some like it 16, some like it 20. Just need to find where it hooks, no wheel hop and stay with it. So, you running a 275/40/17 DR? That should hold.

My buddy just put a torquer v2 in his 01 ws6, cam only on stock 241's it made 409rwhp and 380ish rwtq through a stalled auto. I would guess ur heads would be good for another 20rwhp so whatevers wrong with your setup is probably leaving over 100rwhp on the table...
My buddy did have to upgrade to 36# injecters before this cam BTW his stockers were about maxed out with his old GM hotcam which is only like 218 intake 228 ex. duration and maybe .570ish lift(?) so I would assume a v2 is maxing em out...

88mph is about right for 320rwhp with full weight. If you could pick up the 70-80 rwhp that you're missing. That should be good for around 95 or more in the 1/8, even with the 60' you had that would be in the 7.2-7.3 range, but as stated above there no reason why you shouldn't be at least a tenth faster in the 60' (maybe spring for a torque arm).

blackhawk98

coo...well i i hope im ready for spray now...
