The number that matters are his 37mm chokes. It'll be fine.

 

If he has 37, there should be any bogging issue

 

A 51 will work on a 12a and 13b and make more power (not with 37mm chokes) I don't suggest wasting your time blowing through it. Any older cheap programmable fuel only computer will outperform the weber when used with turbo.

 

Your probly right. But, I have never tried carb and turbo together and I thought it would be a good learning experience. After all, this is a hobby.

 

With the 37, it will be all low end but no top end. With turbo, idk how it will react and whats your plans for additional fuel enrichment other than a rising rate fuel regulator. Yes it will work but theres a difference between "it works" and "it works well"

 

Well, I am using turbo specific emulsion tubes from JayCee that should help a little. And other than that, I am using water/meth injection (pre - turbo) that injects more as I boost higher. I will get it as close as possible without the AI then use the water/meth to hopefully enrich the top end while keeping it safe. I will start with a 50/50 mixture and change it to see what the engine likes. My last water/meth set up liked 70% meth the best.

Also, I might swap to 40mm chokes. Depending on how this set up works.

 

Nice and yes Jack is one of the best with blow-thru. He is very helpful.
