Track experts, please tell me if there's any improvement I need to do to lower my 1/4 mile times. The best time I've hit is 11.6 or higher with 522whp in an EG.

Here's the timeslips from this weekend:

I1: 1.709
I2: 5.256
I3: 7.943
MPH I3: 95.237
I4: 10.053

E.T. 11.861
Mph 120.00
----------------------------------------
I1: 1.780
I2: 5.338
I3: 8.068
MPH I3: 93.579
I4: .000???

ET: 12.022
MPH: 126.817


Does the MPH and E.T. match each other or am I doing something wrong? I was hoping to be in the low 11s or high 10s.

 

Are you using staged boost? Your 1/8 e.t. looks pretty high but, from there on the car comes on strong. Your MPH is good for much lower e.t.'s (Low 11's).

Your mph doesn't reflect 550whp, especially when your 1/8th trap is lower than mine with 240whp.

 

I have to agree both those guys
ur .60 ft is good
but your 330 sucks, i cut 1.95-8s on drag radials and i cut 5.1 330s

i would check a few things, one is the shift point/gearing and sounds like its bogging after first or that the rpm shift point brings u down back out of your power band which give away alot of time

and i trapd 124 on 300hp ish, on drag radials 2400 chassis went 1200-1157 all with 124 MPH

so i think 550 whp doesnt sound right to me, unless you are DRIVING A TANK

Could it be because of my powerband? I think my turbo is too big, and the power doesn't kick in hard enough or early enough. I'm shifting at 9000rpms.

Here's my dyno sheet.


Sorry don't know how to resize.

 

ur 60' looks good. U must be killing the car on the 1-2 shift even blowing the tires off it should do better than 5.2-5.3 330ft and would trap more than 95mph in 1/8th. Id look else were for problems..times dont show 530whp IMO

M&H 24.5x8.5x13 depending on my shift, sometimes I fall outa boost for a split second.

 

what turbo is it?? it does seem quite laggy, my friend has a pt64 with 605whp and im looking at the dyno sheet right now, and at 6000rpms he was at 400whp. and at 7000rpm's he was at 580whp. your numbers are way low 230@6k and 400@7k

I dont know, its something to think about..

It's a t3/t70 Master Power turbo(not sschrome). I think that's the problem too, it's problem too big for my motor 81.5mm, maybe it's time to step down to a sc61, sc63, or t67 which still might be too big.

That graph is pretty bad, your only making good power for 2k rpm and your not revving it at all. I'd go smaller turbo.

 

i bet that car is a highway monster

 

my friend made mid 500hp on a b18c1 he used a 60-1 turbo. He also ran high 10's his best being 10.89 at 126 or something like that.
this was in a EG, with horable suspension

this was at LACR so that very good times

corrected it would be 10.12 at 129.78
