new quarter mile predictions with NA setup

[william SS]

Just finishing up a few things with my latest new setup. Hoping for high 10's all motor if I'm lucky. Mods are...

6.0L 408cid LQ9 forged short block built by TSP. Cam is comp cam custom 240/244 609/612 114 lsa, heads are TFS 235 milled to 62cc making 11.2:1 CR, K&N, Fast 92/92 ported tb and intake/fast fuel rails, racetronics fuel pump, ls6 oil pump, asp underdrive pully, 36 lb fast injectors, delphi maf, ARH lt 1-7/8 headers, ORY, borla catback, ls2 timing chain, Performabuilt level 2 trans with vig 3400 stall. And moser 9" 3.89. Stb, QA1 shocks, BMR SFC, BMR Adj Torque Arm, BMR LCA, EPP pst driveshaft, professionally dyno tuned, MT Et street radials 275/60/15, Mt sportsman S/R 26x6.00 R15Lt skinnies. The only thing I'm lacking is my tune and dyno numbers which will come very soon. I should be at the track and have dyno numbers in the beginning of August.

What do you guys think? I was hoping for something around 10.75 t0 10.95, but dont know if I have enough?

I feel for your transmission.


My best guess will be VERY low 11's.

Are you still running BMR's stiff ass rear springs?

If so I would advise you to replace them with a pair of junkyard V-6 springs.

Also has your pinion angle been checked since the install of the 9"?

ET wise not sure if I had to just throw a # out there I would say mid 11's. You have a 28" tall tire on some 3.89's so I don't think your at the optimum gear choice for ET's.

Has the car made passes yet? If so what RPM are you going through the traps at?

I'm not running bmr springs in the rear, I'm running QA1 springs up front and stock springs in the back right now. My pinion angle has been checked. And the car hasn't made any passes yet with this setup but it will here shortly in a couple of weeks. Do you still suggest that I get the v6 springs for the rear.

Also what gear/tire size combo would you recommend, if what I currently have isn't quite right for what I'm looking to do?

[dpinson]

it is always recommended that you use the v-6 springs over the stock ones they are softer and transfer the weight alot quicker

i think we definitely see some low 11's coming

Are the 93-97 v6 rear springs the same as the 98-02 or are they different?
