Dyno Session of Marvin's D15b SOHC Bracket and Grid Racer 

So so true!

Oh thaaaanks man real glad you liked this one, it was fun and surprised the 2in small exh actually “tried” hehe

oh niceeeeeee that is why he can monitor stuff easily !

Interesting question… this is a “stock” block d15 Lxi counterpart sha kase side dipstick and p2c piston. But with p08 head and skunk2 intake and 2.5 seems to be better Years ago my hatch with a stock block ph15 nonvtec always ran 2.5in and power went from 121 to 127 to 129 and finally 133whp If I was to choose for you? Il choose 2.5in most kase saten porket sohc daw 2in na? Maybe that’s also why I always got 14-15km/liter consumption hmmm

@@SRDmotorsports is that 2.5'' inside diameter or outside diameter just curious ...

@@Rodman8500 I think usually for ss it’s “inside” I can double check later I got some spare scraps here

I hear a lotta guys run 2.25 id on their d15s and mini mes

Yep anything over 2in but unless they’ve shown on the dyno that a d16 works well with 2.25 vs a b16 with 2.5in? I’d still prefer 2.5 as I always ran 2.5 even in my sohc days made decent power and pulled a 15.4km/liter that’s over 38MPG

yup 😎

I knew u would say that! hence I’d always suggest change pipings first (cuz one day we would have the header) haha
