I was wondering if some of you had ran a 75 wet shot on stock ngk tr55's. I have heard of a few. I am just toying with the idea so I can still use my kit, and go fast on a stock ish trans. I can pull some timing too, but have heard most dont do anything with a 75 shot. not looking for you should do this or you should do that, just want to hear from those who have done it. I may do a 50 shot just to toy with.

i have run a 150 shot on tr55s and had no troubles. even checked them a few times and found the plugs burning clean and no sighn of burnt tips

I was even thinking about a 50 shot just to play with. I asked about hp and trans swaps with a GTO hot rod tech/buddy of mine, and he said 500 to the flywheel is the tops. I bet my setup with 50-75 shot would be ok.

Youll be fine with stock plugs with that small of a shot

DO it. 75 is a baby shot! You'll be fine, I used to run 150 on stock plugs

It is $2 dollars per plug. It is also huge insurance. You will probably be just fine, but you are defiantly foolish to not spend $20 or so to give your self a huge advantage that you won't detonate and blow your motor to hell.

A step cooler plug won't hurt your N/A power and at a 75 shot you could run the stock timing, cooler plugs, and some high octane.

Personally I run a fairly aggressive tune(BB performance 93 octane tune), 100 shot, 1* cooler plugs, and 110 when I am spraying.

I wouldn't skip $20 in plugs no matter what shot I was running.
