I finally got my car down to the track this weekend. I don't have a lot of experience racing at a track because i live on Long Island and up until recently we haven't had a track, so i thought id ask you guys here. The car is a 64 Le Mans. It has a 198ci 4 cylinder with a turbo. It has around 200hp with out the turbo so unless it has manifold pressure its a real dog . Turns out i had a real big exhaust leak and couldn't build any pressure at the line. Not until the 330 is when the pressure started ramping in and start making power . So basically from the 330 to the 660 is where it was all in.. I wish they told you the mph at the 330 . If i were to guess it was maybe 45 mph at best lol.

So my question is , is there a way to figure out for now until i fix the car and go back what the mph would of been if it would have left with all the power?

I'll post the time slip

Thanks

Your 660 et is 6.15 ?
I think you'll Be mid nines I'm at 3600# and w tight converter run 112-114 in the eight around 6.0x to 6.1x
You'll run in the 5s if you're not leaving hard now

I don't think your MPH will be much more. I think your et will be in the very low 7's maybe very high 6's

He ran on an 1/8th mile track.
That would be the 330' et.
(I think)

No that was 330 time .

I had a big crack in the cross over pipe so i had zero boost until after the 330 . So it was barley moving the car until after the 330. Most of the mph came after the 330 . So im wondering what the mph would be if i had full power from the starting line . If i was going any faster then 45 mph at the 330 id be surprised ..

So if the car was charging at full power to the 330 instead of moving like a turtle how much more mph would you say id pick up? I mean it left so slow it was embarrassing lol. This motor would be lucky if it made 150 Lb-ft on its best day. The car weighs 3500 lbs with me in it .

Yes that's correct

[charlie66]

Heres what i found today . There was also another little crack on the other side of the pipe .

Who welded that pipe? Edwin. Lol

[johnta1]

With that 60' (2.445 ?) and the 330' (6.155 ?) the MPH of the 330' is probably around 65/68 ?

The 1/8th would have been around a 9 second pass, so you were hauling in the last half. (plus about 10 MPH faster than the 60' / 330' shows)

Get the boost going it should haul some butt.

I like that theory . I don't know why they don't show mph at the 330 .It would be helpful to know that in situations like this . It felt more like 40 or 50 but who knows you might be right.

I did get the pipe fixed and was able to make 8 psi on the trans break..
I'm going to try and get back there this weekend or the next..

The other issue was when the boost did come in was spinning the tires . I don't have slicks . just some Nitto drag radials .. so i know that i need to step up and get some slicks .

Thanks for your thoughts on this ...
