After months of designing, planning, and building, my race motor is completed and installed. First race outing next wekend, engined dyno'ed but still needs some break-in time. My new bespoke race guages look great.
I did an initial dyno tune to get timing, air/fuel dialed, but it was still pretty tight, so hp numbers were soft. Track day this Friday, followed by Saturday and Sunday vintage races at my home track.
Track day last fall I burned a hole in my mild steel headers (too rich or too thin of bent metal?) I decided to start from srcatch and build a stainless system that would maximize the new engine build to utilize both the power and torque in the race motor. I worked with the engineers at Burns Stainless to design a header and exhaust deliver on this goal. burnsstainless.com/
After the build, I sent the stainless headers to Jet-Hot for ceramic thermal coating. (I've used other venders and coatings in the past with mixed results) www.jet-hot.com/
The whole system mock-up went well and the final install is done. Looking forward to a full season of track battles.
Yes, I have the sensor install at the end of the y-connector before entering the muffler. The gauge is discreetly mount above the trans tunnel under dash below my Accusump. It's easily seen when the LED lights are on.
I had a great day on Friday at a Test 'N Tune at my home track. The new headers and exhaust system delivered the performance I was hoping for. My shift points changed as the car pulls way past 7000 rpm now and the breaks the wheels loose in 3rd gear in one of the tight sweeping turns. The new A/F gauge worked great, I was running a little rich, so I'll make so adjustments for that before the first race weekend.
Looking great Dougie. Hope there will be some in car film later?
Just returned from Pacific Raceway in Seattle, Washington state for our vintage race season opener. My car run great, the performance upgrades help me improve my person best time at this track by 3 seconds. I wish my GoPro performed as well, I only got the first 2 laps of the final race on Sunday where I placed second overall and 1st in the FIA G2 class. We had a pretty diverse grid with Chevy Corvettes, sports racers, MGs, Alfas, Truimphs, Sprigets, etc. The weather was clear and a little cold, which made good power, but took a few laps to get any grip.
