SLP maf with resistor removed (previous owner bought it)



At first I thought the numbers were low, but I went to the track and made this on my first pass


currently on the to do list

Strange SA shocks
S60 with 3.42's or 3.73's
Hoosier Slicks

What else should I do for more power? I've already spoken with someone and have an idea on what I need to do but i would like to see what everyone thinks my next step should be. I'd like to see low 11's before i go to nitrous

Props To Martin@tick for the cam help, the TQ curve is flatter than a pancake! The Stall gets right in the meat of it.

 

your numbers are low because you have a big *** 3600 stall lol

 

the 3.73s will help

 

that just goes to show you, dynos dont tell the whole story and max power numbers aren't as important as the ET's. Nice numbers!

 

what camshaft was used?

 

Specs on camshaft?

 

I agree with slightly low numbers for a H/C even for it being automatic, but that time is on point, thats what its all about though, dyno is just a number...

 

231/238 113+3

 

we threw 3 more degrees of spark advance and raised the shift point for 1>2 from 6100 to 6500 and 2>3 from 6300 to 6500, gonna see how it does like this for now.. results tomorrow with a vcm scan as well

 

and lift????

 

FLACO did good on tuning....props to him....

 

They should dub that cam the "A Cup Cam" because that bad boy stays flat forever. Another thing why did you guys stop pulling at 6500 the power didn't even start to drop I bet it would pull to 7000 with no problem assuming good springs of course.

 

why turn 7000 rpm if if stop making power well before that.
11.7 is fast for those mods, good job to the owner

 

bigger headers and y is probably worth 10-15,

 

These motors love top end timing in junction with large headers and good flowing exhaust.. Mine netter 21 hp from 3 degrees 5000 rpm and up..

 

just got back from the track, i added a datalog from the first pass

the first three on the left are from last week, the three on the right are tonight's



the last slip on the right was my first pass, after that, the PCM started to pull timing as the IAT count went up (-2* IIRC). Tranny got hot as well on the last pass to 220f (i hot lapped all these runs) but all in all, the first pass vs my 11.76 pass showed i gained 2 mph and dropped .3 off my time with a 1.70 60ft.

 

Gear wont help much, 3.90 might, 3.73 is a waste. 4.10 with a 275/60 drag radial would be the right combo.

Buy some double adjustable rear shocks.

Put a cutout on it.

Tweak with those mods and it will run some 11.40-11.30's

 

Ditch the MAF and put on a FAST with a bigger TB. I gained 20/20 going that route on my 346. You should do as well or better.

 

1 7/8th headers and fast 92 and matching TB is in the works along with a plate system after the rear end and shocks are put in.

and believe me, i wanna ditch the maf. The maf was giving me problems when the car was an ls1, the previous owner had it tuned by a moron in houston who tunes without a wideband and thinks "he knows what cars want by smell and hearing"

 

Turn It to 6800-7000 rpms and you will et quicker. Especially important with only 3.23 gears so it don't drop back so low in the power band on shifts .
Good pass's , my lq4 in a 6 spd car with 4.10 gears shifting at 7000 with f14 cam 232/234 112lsa +4 and run 11.32@122.
Point is, run the rpms up some.

These lq4's are tough .
