Small amount of nitro or m5

<< < (2/2)

COKER:
'Spud,

Congratulations on your magazine article you deserve it. On the low amount of nitro issue Rich Barnard out of Ohio had a big block with aluminum heads and 12.5:1 compression on alky and best he ran was 8.16 and was frustrated with the performance of the car. I mixed him up 25% and right out of the box he went 8.02, 8.01 and on a 8.00 index run he went 7.96. Like you I don't recommend the nitro much with 14:1 compression. It did seem to me with the engine set to run nitro you gained a tenth for every 10% you added. I found it to be a good tuning tool.

Yes I did. But I will try it again soon. I got a few things figured out.
