Well, I finally got a boost controller and cranked her up a little today at the track. All runs were on 13 psi with 18* of total timing with a mix of 114 and 91 for about 105 total octane. The DA was about 950' and the track prep was marginal to say the least. My MT Drag Radials were showing cords, so I got a temporary replacement in the form of 26.5" Hoosier dirt track tires. They're better then radials, but are certainly nothing like a real drag radial.

Here is the link to the buildup of the turbo kit and details of the combination:

Anyway! On to the important information!

1st Pass - Spun. Alot.

1.93 60'
5.49 330'
8.05 @ 98.45 1/8
10.16 @ 117.37 1k'
11.91 @ 127.51 1/4

2nd Pass - Spun alot more and short shifted into 3rd to get me going

2.01
5.74
8.30 @ 98.19
10.42 @ 117
12.17 @ 129.53

3rd Pass - The track finally starts to come around but I get extremely sideways on the 2-3 shift and have to lift

1.78
4.96
7.55 @ 97.64
9.68 @ 116.52
11.43 @ 128.90

4th & 5th Pass - Basically identical passes. Now we're getting somewhere. Hitting the rev limiter at 6200 in 4th through the traps.

1.79
4.96
7.39 @ 101.97
9.45 @ 119.43
11.16 @ 131.31

6th Pass - Best of the day.

1.76
4.92
7.35 @ 102.34
9.40 @ 119.87
11.11 @ 131.66

So there you have it. 131+ mph on the stock short block with a stock fuel system on DIRT TIRES! I'd say this .68 MP T70 is PERFECT for a 302 ci engine.

Re: Who says a .68 exhaust housing is too small?

NICE! that is good to hear because i thought my .68 a/r was going to choke mine! nice numbers!!

 

Re: Who says a .68 exhaust housing is too small?

Congrats!!

Definitely update the thread when you get the video.

 

Re: Who says a .68 exhaust housing is too small?

what type of syspention are you running? i love the nubers for sure. can't wait for mine this spring. i see your running an ssauotchrome waistgate right? what sizes? how doe sit control low boost? and what did you do to tune it?

 

Re: Who says a .68 exhaust housing is too small?

Awesome! I'm proud to say I had a part in making you do the turbo conversion. Put it like this, on the bottle it went 11.02 with alot of nitrous at 123mph. With no changes except the turbo and less gear it goes 11.11 @131 on a fucked up track and shit tires. It's an easy 10 sec car now when before you would have had the perfect passt to run 10's. GG Mike!

 

Re: Who says a .68 exhaust housing is too small?

awesome. i guess you are making about ~570 rwhp ? thats a nice mph planning on going back with slicks to get some lower numbers ?

 

Re: Who says a .68 exhaust housing is too small?

I have Strage 10 way adjustable struts in the front and lakewood 50/50 shocks in the rear. The rear suspension consists of baseline suspension upper control arms, and Pro3i weight jacker lowers. The TurboXS wastegate is working great, it is a 46 mm. The wastegate spring is set on 7 psi, but depending on how cold and dense the air is, it makes anywhere between 7-9 psi. Holds the boost rock steady though, no creep. For tuning, I've done a few things with my tweecer, but it's mostly just timing and fuel pressure.

the car only weighs 3250 with me in it, so according to the math it's making right around 500 rwhp or so. I'll take it to the dyno soon and find out. Slicks are definately in the plans. I'd like to see some 10.50s or so.

 

Re: Who says a .68 exhaust housing is too small?

sure is fun going 10.5 for the first time

hope you got some axles, cause one may pop like mine. oh and i also bent the lugs on the other axle launching at 6k

 

Re: Who says a .68 exhaust housing is too small?

waht you pay for the gate?

 

Re: Who says a .68 exhaust housing is too small?

I bought it from a buddy of mine for $50.

Very Nice!

Re: Who says a .68 exhaust housing is too small? *Update: Videos!

my prediction is you will blow your engine very soon with that much back pressure. good luck though.

 

Re: Who says a .68 exhaust housing is too small? *Update: Videos!

Great numbers. What transmission and clutch setup do you have in there?

 

Re: Who says a .68 exhaust housing is too small? *Update: Videos!

please clarify your prediction.

 

Re: Who says a .68 exhaust housing is too small? *Update: Videos!

+1

I'm doing a very close build on my notch.

 

Re: Who says a .68 exhaust housing is too small? *Update: Videos!

asshat

 

Re: Who says a .68 exhaust housing is too small? *Update: Videos!

HOLY CRAP MAN Congrats on the numbers, its gonna be crazy when you get it hooked up.... Talk about some motivation to put mine together....

 

Re: Who says a .68 exhaust housing is too small? *Update: Videos!

Thanks everyone. I couldn't be happier.

I've got a old style TKO with a spec stage 3 clutch. Works great.

 

Re: Who says a .68 exhaust housing is too small? *Update: Videos!

Good job on getting it done w/ minimal traction! What rear suspension do you have?
