7 minute(s) of a 67 minute read

Ive been working on the car alittle bit here and there , Motor is out , trans is rebuilt and sold New K member is in etc I picked up some new BBK caster camber plates so the front end should be back together ASAP

the car weighed 2900 lbs without me and with a 1/2 tank of fuel , that was with the stock K member front end etc and an Iron block motor and heavy turbo kit up front .

The car uses a TCI 3500-3800 converter meant for a th350/400 behind a LSX motor.

I should have some more progress to report after the weekend.

Ok here are some updates for this year:

Had the car on our Dynojet and made 510rwhp/495 rwtq on 11psi and pump gas but have not had a chance to put it back on with the boost up.

So far the car has gone a best of [email protected] with a 1.53 60 foot , That was on 13 psi and pump gas. I have since added airbags to the rear to try and flatten the car out as well as upped the boost to 16psi and I am trying to get a 9 second pass out of it before the year ends.

I have driven the car on 1200 km round trips raced and drove home as well as street drive the car ALOT! It has been great and not given me many issues at all.

I tune it , I don't run 16 psi on pump gas I run it on a mix of 94 pump and 109 unleaded race gas and yes this car see's a very heavy dose of meth timing is between 18-20 degrees depending.

[email protected] last night in some nasty heat with a crappy 1.63 60 foot also went 138.46 on one run.

Here is a little video of it from last night, car spun pretty hard but still managed a 10.40@135 on 14 psi and straight pump gas. The car in the near lane is a friend of mine His posi crapped the bed as can be seen but the car is a R block 306 with a novi 1000 blower and a 150 hit and has been 10.3 so we are generally a good race.

Gonna go for 18 psi next week and see if I can get my 9 out of this heap.

It really needs adjustable uppers not to mention the track conditions seem to vary run to run like one run I can leave at say 6psi and 3400 rpm the next run I try that and it spins HARD or I leave at more boost and it blows the tires off so I back it down some and then it leaves like a slug.

I will get it figured yet.

On 8 psi it made 450rwhp
on 11psi it made 510rwhp
SO on 14 I would guess 550ISH
and on 16.5 all the calculators put it right around 650-660 rwhp . I guess I could put it back on the rollers seeing as how I own a dyno LOL

Well after going up a bit in tire size and changing a few things on the suspension the old heap of **** pickup truck motor finally did it 9.99@140 the car made 5 passes over 140 mph and it was all on 14.5psi and straight pump 94 with meth. The car finally left good with a 1.48 60 foot. Overall a great night of racing ran new personal best et,60 foot and mph and did it all on my street set up with the boost down and pump gas !!!
