Hi, this year has been our first real solid year with this combination and we dont have a lot of track time to look at. Realistically we have 2 meetings worth of data at 2 different tracks, plus this weekend. We had a fresh engine and box at the start of this season, the new engine destroyed our new box and left us out for a while. Our first meeting back and we were pulling large wheelie's but ran a new PB of 8.68 @ 155mph with a 1.298 60 ft. 1/8mph was 126.34 @ 5.544. We fitted the car with wheelie bars for the next round, where we ran a best of 8.5992 @ 151.58 mph - 1/8 was 5.4252 @ 125.88 MPH. This was on a track prepped for Top Fuel, Pro mod etc.
This weekend's passes was on a very cold track, I dont have any data as to track temperature but I know we were struggling for traction and the car was moving around more from around 330ft. The car was wheelieing heavily though at this meeting, we had the wheelie bars in place, and i believe the height was set the same as at the previous meeting, but the car kept bending the wheelie bars on launch, so we will be looking to improve those for next season. However all year i have felt that the car was nosing over at the top end, and thought that the speed was low compared to the et, which makes me think that there is a bunch more to come when we sort that out.
To give you an idea about how hard the wheelies were ill post up a couple of pictures.
The last picture shows that the front wheels are still in the air at the point that i shift, which is after 60ft, so the 60ft time may be with the back wheels.
I think at the moment the heads / exhaust are restricting the amount of rpm we are turning and killing the top end mph. As i say the heads are unported out of the box SCJ's, and i think they are restricting the motor from around 6000 rpm's. I was always trying to keep the motor from wanting to spin more than 6500 rpm's through the traps to keep attrition low, but im wondering if she's not spinning enough. 151-154 mph is 5900-6000 rpm's plus convertor slippage.
