Car is 1989 Honda CRX I made 190.2 whp on a mustang dynanometer and 124.9 tq

Now the cams are cat cams and they are the race ones but by the looks of the sheet they flatline at 8 grand, the tuner told me that past that it is straight so he stopped it there, should I get a cam like the crower all motor ones, please sugest

oh and 1-4 mile guesstimate is appreciated

 

setup is
b18a b16a
ported and polished, polished cumbustion chamber, 3 angle valve job
titanium retainers, dual valve springs, cat cams full race cams
skunk2 manifold
cam gears
FPR
hondata stage2
510 evo injectors
airmass header (i know i know)
2 14 crimp bent exhaust
test pipe
CTR PISTONS

what kind of gains will I get with a 70mm tb and a an-r header

thanks

and what you guys think

anyhting is appreciated

 

also what is the diff mustang dyno vs others I hear it dynoes lower

 

70mm is too big go with 65 or 68

and with the AN-r Header get a 2.5" mandrel bent should be way better

 

can you post a graph with the a/f ratio. Mustang dyno's give lower numbers than dyno jets. But as long as you are using it as a tuning tool I guess it realy doesnt matter.
On the tb question I think you should look at your goals and buy one that will help you reach them. So you dont by a 65 now and a 75 later. Thats what I had to do and tb's arent cheep.
