ran a best of 14.02@98.9 w/ 2.07
this was with engined heat soaked, street tires, 93 octane and my 235 lb ass drving. Temp was around 70*, humity was high enough for the mosquitoes to be a problem.
I'm sure I could have ran a 13.8 or 13.9 @100 that day if I would have been able to cool the engine down, work on my launch, mess with tire pressure, etc.
Is this a decent time for my mods?
05-22-2011
Yeah right about where you should be.
05-22-2011
cool, thats what I was thinking. I figure with some cooler weather, traction, race gas and engine cool down I could shave a good 4-5 tenths off that time.
05-22-2011
I ran a 14.1 with pretty much the same mods. Except I was trying to narrow band tune so my tune was ****.
05-22-2011
ah yes, that can be tough. I'm converting to e85 sometime soon here so I'm not gonna get to hung up on it. I'm hoping for low 13's after I make the switch but we'll see.

What sort of boost levels are you seeing?
I'm curious because that pulley seems a tad on the large side.
05-22-2011
6 psi @ 3000 rpm
7 @ 4000
8 @ 5000
9 @ 6000
I have a 3" exhaust and no cat either BTW, not listed in my mods for some reason.
05-22-2011
Hmmm...
Lots of increase.
Have you changed your valve springs?
You may have valve float and that may be whats slowing you down.
05-22-2011
never changed valve springs, pretty sure I'm not getting float.
What should I be running? Like I said, the car has more left in it.
05-22-2011
well IIRC with 1.9's on the stock cam you shouldnt be seeing much increase in boost.
But you're seeing 2 PSI increase which is what I'm seeing on the stock valvetrain.
edit: guess i'm dumb: http://www.w-body.com/showthread.php...-GTP-Dyno-Vids
Seems like you'll still get the same rise.
05-22-2011
your pretty much maxed out. You would need a bad ass tune at this point to touch 13's
05-22-2011
PLEASE!!! IC, E85 and get some slicks for this car I along with everyone else on here NEED to see how fast a car can be setup properly WITHOUT heads, cam and everything else that has to do with taking anything below the LIM apart.
I firmly think you can get wayyy into the 13s maybe better on stock heads and cam. (no turbo either since technically I guess its bolton!)
Everyone just says ehh throw a cam in it and go buy some heads. Me personally Id love to see every aspect pushed until heads and a CAM are absolutly NEEDED!

namely a better belt driven blower?

I've ran 14.1 with about the same mods minus the rockers. You should be faster.
05-23-2011
Shift points?
Rockers take advantage of running it higher in the RPM range...and the stockers might be holding you back...I'd never run anything more than 1.8 rockers on stock springs and would never shift over 6K on stockers.
Go get behind some 7 second car and root it and give it hell. a 1.90 60 vs. your 2.07 would net you very close to a 13.8 if not faster.

Please tell me you havnt been drinking all the TVS koolaide! Ill believe it when its done and still dont think the gains will be as much as hes expecting.Originally Posted by matt5112

Honestly u should be faster, what's your location and altitude (sea level means a lot)
05-23-2011
Also when I did my rockers i lost a little boost as the motor is flowing more efficiently, and you'd know if u where getting float
05-23-2011
your not gonna cut much better 60Ft times with 2.93 gears and street tires either. Nice runs

Bullhockey ya nut.
I got sub 1.9's on street tires with 2.93's. Driver mod fool.
Duh.
