Exactly Carl!

The bar wheels hit down way too soon eh? They were just acting as levers to unload the rear tyres eh?

That will be rectified for next time out after the tranny rebuild.

Jim!
I was offered the use of the Glide from the Slingshot my friend runs Which I have also driven down to 9.4 on part throttle :) Damn! that's a scary thing to drive for sure. Sadly too much messing around to get it fitted for a trial run I think. I will wait for lockdown to end so I can get my 350 refurbished with better sprags and clutch packs etc. Then I can go testing again. I'm itching to get this thing back on track asap. I know I may have to wait until late in the season and weather may not be good when I can eventually roll her out again. Based on my old calcs of the old Blown and Nitroused Rover engine I am Sure that the car will run as low as 9.3 on the nasp SBC motor. I need to confirm that on pump gas and then try C16 fuel to see if it will do any better?
THEN I will have my baseline tune on both fuels for the MGB. If the car only makes say 9.4 on track I know that I can get into the 8's with a sniff of gas for sure. Exiting times are ahead for sure Guys! Its all down to when lockdown ends and when I have the spare money to refurb the tranny.

Regards to all and please stay safe.

Pel!!
Itís great to see the old fighting B back out on track at long last, itís been an epic journey for you and I hope those 8ís come rolling in soon!
Have a chat with Paul at Edge Performance Transmissions. He has mine in for a complete rebuild at the moment and is also supplying a torque converter thatís matched exactly to my car and drive-train so I wonít drive through it at the top end or over power when launching and it will still be road friendly.
Theyíre really great to deal with and keep you updated through the process.
