Katech Torquer 110 goes 10.50's@131 in AZ
Track side weather station showed 1591 DA at 11:00 a.m. ......didn't check for a new reading after that but guessing 1900+.
Not too shabby for a torque biased cam that runs out of steam at 6300 RPM
Almost the exact same run at 11:00 and 12:00 LOL My shifting was not particularly fast today (pretty rusty), but I didn't miss any gears short shifting at approximately 6800 RPM.
#713 ...... race weight this day was 3159 lbs, with full interior, just under a 1/4 tank, and 295/30/19 runflats on the front .....3400 on the dot with my lard *** in the seat.
I ran a 10.404 a few weeks ago, with a 6.587@105.22, but the slip is incomplete due to computer issues with the new timing system at Wild Horse Pass aka Firebird Raceway.
Oooh....by the way. On the way back from the track

Awesome. Great times. So to clarify, this is cammed only?

CE is on when car is off is pretty normal. If it was running I would be more concerned with zero oil pressure.
Great fun today.

Thanks, guys.
With some cold, dense air, a 5000-5500 RPM Ranger style launch, and excellent track prep, I think a 1.45 60' and 10.2X@133-135 might be possible. This cam really runs out of steam at 6300-6400 RPM, so whatever you're going to do to run a stellar ET and MPH with this cam will REALLY need to be accomplished in the first 330' mark....you've really got to take advantage of the low to mid-range punch this cam has. If I get another chance at this track, I might also raise my Hoosier's hot tire pressure to 20 psi (from 17 psi) to see if I can eek out that last MPH from her....this track was sticky HARD !!! LOL

The only caveat I have is I built my package to run on E85....I milled the heads .030 to raise my static (and dynamic) pressure to take advantage of additional torque (550 lbs/ft). When I run it on the 91 pump gas I have here in AZ, the dynamic compression I have will not tolerate anything over 18 degrees commanded total timing, and it will pull as much as 3-5 degrees at WOT in 4th gear at 5200 RPM when KR is present.
E85, and Sunoco GT260 allow 25 and 24 degrees (respectively) with this much dynamic compression. If I was to have this timing available at all times, and run on 91 pump gas with my .030 milled heads, I'd need to bleed off some dynamic compression by changing the intake valve closing event. This would also kill some of the low-midrange torque, which would allow the car to hook better at WOT on a street tire, and tack it on up top HP wise, where drag racing and highway roll racing can take advantage of it.
The K501 cam would get this done

I figured it was getting the job done for your needs. It's good to see a good time from that cam with more time left in it because the fastest I've heard of or seen with it has been in the 10.7-10.8 range at 130-131 mph. I'm a drag racer so I decided to go with a bigger cam and not worry about the low end as much since I spent all my time at high rpms

There have been a few others who've touched the mid 10's with this cam, at 132-133 MPH traps, but it is NOT a drag race cam by any stretch of the imagination.

8.5 is the dynamic compression with a stock 11:1 compression LS7with stock heads and combustion chambers. I'm milled .030 as well as having the Torquer 110 first generation which does not have the 4 degrees of advance, so I think we calculated approximately 9.5 for me IIRC.

I know you said you wanted to run e85 to take advantage of the milled heads and cam. would running 100% meth injection instead net the same gains? I've been wanting to run that route seeing as how I don't live in texas anymore and e85 isn't readily available .
very nice time btw

Nice job!
A car that runs 10.50s that you can drive home from the track and get 30mpg? You can't beat that.
