Went to the strip last weekend and ran a few times. The track was not in good shape and the track temp was over 100°F. Kept spinning off the line and the car didn't feel very strong over 5000 rpms. Ended up running a 13.0 at 109 mph. Got home and scanned for a few WOT runs and found to be pulling between 2 and 5 degrees of timing over 4400 rpms. This was due to the tune I had in there pulling timing for IAT and ECT. :thepan: Backed that out and pulls strong again all the way to 6500 rpm. Oh well, at least it was a sunny day with lots of great cars to look at and watch run down the track.

This close to V-Day ? Do you have a spare diff sitting in storage ?

 

[STAGEUP]

Good run!

Don't be surprised if you dont gain much from adding your timing back in when its that hot though.

The black car in all these photos is mine. I have both the RXx-1 and RXx-2 upgrades. I have some other mods after the photos were taken.

What H/C are you running? and sorry for sounding stupid but what is a RXx-1 and RXx-2?

 

[maloCoupe]

Definately some improvements to be made on the 60'...........I am sure the Hoosiers should take care of that.

Look in the link to the "Corvette Doctor" for a list of what those mods are.

They are ported, polished stock 243 castings with .650 lift dual springs, double thick locks, titanium retainers and I now have 1.75:1 stainless steel roller rockers. They didn't have the roller rockers when I had the Corvette Doctor install them.

Yeah, the track was super slippery and it would spin relentlessly with the Toyo Proxes T1R's. I have gotten a 1.996 there before on T1R's. Also, the Hoosiers are not for that, they are for road courses and with the wheelhop I'd never be able to heat them up at the drag strip.

Thanks.

Did you get a set of Hendrix axles yet? I'm still waiting for someone to test those out at the track and see if we can launch better with them. That's one way to knock those 60 footers down.

 

[Guest]

Nope. I can't justify spending that money right now. I don't usually go to the drag strip so I don't really ever get into any wheelhop situation. Most of the time when I break the rear tires loose it's around a corner and it doesn't hop.
