OK a few test results from this weekend. First the place was packed, very surprised the pits so full, unloaded went to tech and found out my belts were a month out of date  . Got that fixed & went to get the first run with front shocks set about neutral.didnt set the twostep so it didn't leave real hard but ran a 9.95 with 1.46 60 ft @ 135. Only got two runs Saturday so I adjusted front shocks a little looser.checked plugs was a little lean looking changed jets from 92 to 96 made second run around 1:30 and was hot, air was 2700 second run it went 9.89@135 and the 60 came up to 1.42 day was over for us so I changes high speed bleeds,adjusted shocks again and changed chip in launch from 3000 to 3400 and went to Sunday eliminations.launched and watched the other guy and never noticed I went red so I was way out on him and lifted.got my time slip and went 9.89 @122 With 1.38 60 but felt like its leaving soft. Not a bad outing considering that's the first time I've been in my car in almost a year and everything is new.there is a lot left in it but only three runs so I need a good TNT to get it sorted. That last run it went 6.22 in the eighth so I'm gaining. Going back the 16 th next month so I'll hopefully have a few more runs.

Just shake down runs and you`ve change just about everything on your car so back to square one. In the vid I saw it wasn't transferring weight and spun a bit so test, test and test some more Mike and you`ll get it..............  Lookin at that slip again, I`d bet you were on a 9.60-70 pass only going 122............

Thanks everyone, going back in a couple weeks, first time with coil over front end and double adjustable shocks. Didn't get all I wanted but happy I had no issues with all I changed and did get a personal best. Hopefully I'll get more than three runs.

Not trying to poopoo numbers here. A question was asked and I gave my answer. Generally depending on the dyno and it water tower capacity or where the water comes from they try not to get them to hot. It may take too long to cool down between runs. The dyno this engine was done on from my experience is not a happy dyno by any means. Generally you can out the ole moroso slide rule to the numbers and have a good idea what an engine off of the Pettis dyno will run in the car. Once the car combination is optimized.
Yes it is true you can make a dyno pretty much spit out inflated corrected numbers. That's great for the dyno crowd. Thus why I always say I want to see a quantifiable result from any dyno when it comes to actual ET's. It is pretty standard practice industry wide to make the last pull with things cool off as much as reasonably possible. It does not mena you get 40 more HP buy any means. You will generally see a gain but it aint gonna move that much. Oil temps and water temps are always monitored, or at least shold beon the Dyno.
My engine that was just on the dyno it was hard to get water temps up very high. The reason being the facility uses a city water connection on the dyno. So they have and endless stream of cold wate at their disposal. Just a matter of running the water pump for a few minutes to get the engine temps down. The dyno we used is notoriously stingy for the numbers it kicks out. It is a new DTS/Superflow unit with a state of the art no expense spared dyno room. It has been pretty consistently down on power from where we used to use. And that dyno was considered stingy by some and honest by many. Numbers usually went dead on to the moroso wheel from the old one.
Interesting what you said, I had a 499 that Kenny L built when he was with McCandless. 15.19 compression Indy head, long story short engine ran hot then finally got temp down to leave at 160 degrees, lost a tenth and one haft. Called Kenny, was told that engine had to leave at 200 degrees to build heat in the heads?? Did that and ran the good number again. A little confusing when some say run it cold and some say run it hot??

Nice first outing, i'm suprised you didn't run it all out after you went red though.

I agree but i'm sure in cooler weather and a bit more tuning a 70 is achievable. Mick

No clue on that but I scrubbed 10+ mph and lost a chunk of et but don`t remember exactly how much. Plus as I told Mikey and was correct in that the dyno tune would be off and it is. Jason had the mixture screws 3/4 out and it ran bad till he brought em out to 1 1/2 where I had em and it wants more jet as expected also. Dynos are a tool and a way to see if our junk leaks and set BASIC starting points that`s it imo...........That car will go easy 9.60`s or better.............

Thumper,
If we look at the 1000 foot numbers on his full run where he didn't lift it took him 1.649 seconds to go from 1000 to 1320 under power.
If we take the 1000 foot time on the run where he lifted and add the "known" split time from 1000-1320 the car was going to run about 9.82 as indicated above.
Full pass
9.897 to 1320
8.248 to 1000
9.897 - 8.248 = 1.649 seconds
Lifted pass it was 8.171 to 1000
8.171 + 1.649 = 9.820
No one is doubting the car has the ability to run in the 60's, but it wasn't going to do it on that run.

Cool...........I know the math is pretty close but scrubbing 13+ mph just doesn't calculate in my brain............
