What size do your rules allow ??  How much fuel delivery do you have ??  are RPM's open or limited ??   We used to run a TV77 on top of a 3LM466 with about 400 cc's of fuel with open RPM's many years ago. Worked quite well and I suppose the HP was in the 600 to 700 ish range  ??  Now we must run a max of 3 inch air inlet and the fuel is double and the HP is around 1200.

When we first went to twins, we had been running 7th gear in the 6700 lb class with a 190/200 chassis. Adding the TV77 (or an S-3) on top of the 3LM466 allowed us to shift up into 8th gear.  This was with 24.5 x 32 tires and open RPM.

That is a question???   No bubble in the hood, but inlet and exhaust went out thru the hood sides. If you are trying to hide twin turbos so no one knows you have them, good luck with that idea.
