So last night I got in to Wolcott and spliced in the newer MOSFET 07-08 and I runs extremely cooler. Wish I had a temp gun to see but the OE one ran wicked hot after 2 min of idle, hot enough where you would tap it and say okay I wont touch that again. The new one runs extremely cool, after a 45 min session on the dyno it was luke warm.
So John put her up on the dyno did a couple pulls today.
Heres the history so far......
Heres from 3-4 yrs ago when I went from some pre-made map to a custom tune by the dyno guru...
From 110hp to 115hp with a very nice smoothening of the power curve....
A year later I went in for a scheduled Drs check up... also at this point an Ignition model was installed however left at 0
She put down 109hp after some re tuning of the map it was up to 111hp. Now mind you this is now on a larger / heavier 180/60 race tire, which caused the loss of power...
Now almost exactly a year later back for a visit again. The replacing of the rectifier removed the entire bucking issue I had during the last round of racing so that was a relief to see. Since its last visit I re built the transmission and added a thinner head gasket (-.40mm). I presumed the A/F wouldn't be affected much but still good to make sure its in peak condition.
So heres is where we are at today 113.21hp!!
Just rolling on to the dyno with zero timing it made 108hp after some tooling of the A/F and adding in 4° of timing it put down 113hp, so ~1.55 gain. I don't have a comparing to the 108hp run but there was a nice mid range gain of +2-4hp in the 4-8k range too, although Im not there too often during races.
Given its a 10yr old bike I'm still plenty please with the power it putting down and as you can see the power curve is perfect.
During last round I ran a compression test and all the cylinders were fine but on the lower end of the tolerable allowance (165psi, min 155psi). Im sure I'm loosing some power there, but hey I have almost 30k on the odometer. Over the winter Im most likely to re-hone the cylinder jugs and new piston rings possibly new pistons too, cost prohibiting
But I cant say enough about John and how well he does his job and the effort he puts in to it.
If you're in the NE area I highly recommend him, his link is in my signature below
