well went this morning to MIR for some runs and got 5 runs in but 2 of them 4th locked out on me. Average was around 12.5's due to spinning all over the place. I dropped my tire pressure to 25 psi, got a good launch and got:
60': 1.657
330: 5.011
1/8: 7.779
MPH: 87.48
1000: 10.117
1/4: 12.031
MPH: 118.51

2.3L, DBB Black, 1100 HiZ, SpoolinUp COP, ported manifold, 245/40/18 street radials. Mixed 1/4 tank of 103 octane with 1/4 tank 93 (tune was untouched from my 93 map). Temps were around 75 degrees or so, no winds. Is this pretty much average with the Black or is does something not look right? Thanks.

 

What power level are you at? Full weight car?

 

i would assume a better trap speed with a stroker and fp black. Thats a stock turbo e85 setup or bbk pump gas set up trap for a lot of guys on here. Like above said the weight and power level could be an indicator for you also.

 

Yea something is up. I ran that fast on a stock turbo on 93 oct. with a boost controller, ic, and a tune. Even considering 4th locked out, your 1/8mi mph is way low.

 

Seems like the car is low in power for your setup. The spinning will probably explain why you only went 12.X with a 118mph trap. I would think it should be able to trap at least 124-125.

 

It's full weight minus the spare tire, and VD is showing 424whp. I ran 12.2@116 with my BBK full last year but the weather was cooler. I too was expecting 120's but wasn't sure the weather effected it as much or what. I leak tested up to 35 psi (running 31 psi) and nothing, so something's up with this. Thanks for the input, I'm still trying to figure this out.

 

I trapped the same with stock block on fp black at 24psi on 90 oct. Your whp seem a little lower then normal as well. Maybe its your tune?

 

It's probably the weather!... I was trapping 116-118ish when its warm/hot...trapped 124ish during cool weather on a stock block dbb fp black setup, pump gas.

 

could of just been hot. my buddy with a bbk full ran 11.8@118 with a 1.9 60ft on a 80 degree day. your setup should be mid 120's imo.

 

75 degrees is hot?

 

Wouldn't his 18" wheels be kinda heavy and have more rotational mass?
Haven't seen to many people run with 18" rims. 15",16", and 17" at the most.

 

trap is low. that 60 ft on street tires is descent and should have netted you at least a mid 11.

I cut a 1.6 60ft on all season 18s. I lowered the psi to 22f and 20r.

 

Thanks, hopefully I fixed my problem. Noticed my turbo "band clamp" was loose and dripping a little bit of oil. While I was checking things, I noticed some oil on the passenger side, apparently I forgot to retorque the valve cover after I had it powdercoated. It seems to be running a little better, have to wait for these 100 degree temps to go away before trying another run. If my ET stays the same, there has to be an issue with the tune or something.

 

gotta work on that 1-2 shift. 5.0 for the 330ft is a bit slow. you'll get it!
