$25 entry fee at the track, and we could have saved all this typing....lol....and had fun.

Yeah, but then you don't get those cool dyno printouts to show everyone.

Everyone knows a fancy dyno sheet trumps an ET slip every time.

Where were you 100 posts ago. That seems like a lot of work going to a race track and actually racing your 🚘

Waiting for the sequel.... unexpected time slip results

Here is what a chassis dyno session looks like with a manual transmission. This is some cam testing I did a long time ago.

You can right click on the picture to open in a new screen and then if that isn't big enough to see just use control and + command to enlarge.

Thanks for that Andy.

I still haven't heard back from the dyno shop about getting the raw data files. I'm going to give them another call today after lunch.

As for the guys that keep beating the 'take it to the track' dead horse already, I get it! I acknowledged this pages ago and stated a track day is on the list. I'm not one of those dyno sheet snobs that measures their self worth against a fancy print out. I only wanted to know what could be possible causes for the lack of a broad torque curve that these motors are known for.

I wouldn't worry about it. It is summer time, enjoy the car. If you find something you want to change then put it on the list for winter time. If you make it to the track great, but if not who cares. I don't feel a need to take my car to the track.

Do your thing however you want and enjoy.

if you ever do head out to a track, post up ahead of time.
It's a good vehicle for a "what will it run?" thread.

Lapeer is looking really nice these days....

i went to the track first, had a lot of questions and went to the dyno second. the track info/dyno info plus a few other tid-bits answered my questions. I agree with andy and zippy; just enjoy it! questions will be answered in time.

I wouldn't worry about it, you're simply asking for some help and the graph was necessary to facilitate the discussion.

This is the first time I've ever posted a power graph on any forum, and have never made any dyno hp claims in any post on any of the stuff I've had on either an engine or chassis dynos. And like Lew, these pulls were after about 30 passes at the track, and the dyno session was for testing purposes, not bragging rights, so I know he's not talking about me.

I like having my cake and eating it too.

I want the big dyno number...... and the low time slip. 😎

I have to admit, there is a little satisfaction and fun in having the lowest hp dyno sheet, but holding the quickest and fasted et slip.........and that's with a heavier car to boot.

You do present a very good argument 🤓

And of course, that’s a way better scenario than having the big dyno sheet number........ and the slow time slip.

I think you done pretty damn good with a fat car, no gear, and stock exhaust!

Mark,
Sounds like the ride is a beast...would love to meet up at the track...pick a date and let me know.

Dad and I are shooting for this Saturday. Might be Ubly, don't know. I'll give you a call.

Life has been forcing me to put the hobby on the back burner for a while, but I took a week off from work and got the dyno files and made a track run. I took the last two runs which were the best and did power vs time, power vs speed, and speed vs engine RPM. They're attached to this post.

Here is the track run...

Had issues with my Dad's car and didn't get to Lapeer until almost the end of the day. Only had time for three runs - the slip and video are of my first; which also happened to be the best.

This was actually my first time down the track and you could probably have guessed by my reaction time. If you listen carefully you'll hear the motor break up a little at the top. It got much worse on the last two runs. I think what the problem was is I ran it down to a quarter tank and the pickup wasn't submerged after the launch. Live and learn...



A buddy came through and gave me a factory lockup converter for my transmission. I guess I'm mulling whether or not to put it in now.

I appreciate the input guys.

Did you happen to notice the rpm at the finish line?
4.10’s and what diameter rear tires?

I don’t think 13.06 is what you’re looking for...... but I’m sure there was some sort of expectation when you were putting it together.

Did you take a data log in the Sniper for each run? If so, you should be able to look at them to see what might be going on. Do you have a fuel pressure gauge hooked up to the Sniper? That would help too if you have it.

I think the car sounds great and it motors right down the track. Seems like a really solid 12 second car once you get some more seat time.
