Whats up guys, I finally got something done to my motor. I swapped the top for 4v stuff and a couple other things also. It is a different drive now, more so at above 4K rpm but kind of disappointed. They dynoed me at 264whp but 0-100 isn’t that much quicker. I haven’t made it to the track yet but my gtech meter (which is spot on with the track clocks) is saying im 13.939 only .3 quicker in the ¼ mile then before (npi 2v). Either way F/I will like this setup better.
I do like it and it sounds more aggressive too.
Thanks for looking

 

what are your other mods? 13.939 seems a bit slow for a 264 rwhp car. 60ft time? trap speed?

 

I have a auto with a shift kit and 3.73’s shortty headers with high flow cats, sub frame connectors, and the front end has a tubular kmember and a arms with adjustable struts and big brakes. I also have a dyno tune with an sct switchable chip and some other little boltons too.
I was wondering how much a stall converter (3000) would help?
My 60’ time was 2.4 L and trap was 105. So I think there are .2-.3 ths left on the table but was still hoping for more
the black run is the new setup and the red run is npi 2v setup

 

That seems REALLY slow. I know of Mark VIII's with only 4.10's running those numbers. Seems like you should be running mid 13's.

 

how hard was the swap?

 

Is your car tuned properly?

 

the 4v heads help yes... but its still a 281

 

well it definetly looks nice. sorry you didnt get as much as you thought you might out of it,

 

thats not bad at all, some tires and a S.C(stall not s/cer) get the 60' down to a 1.8 and thats 12.9 territory (105 mph trap.), i don't trust those electric meters at all.

 

Looking good....sounds like a tune might help you out!
