did they tell you you would have to tune the length/diameter on a dyno too?

i will be doing this on my next B20...

If your using your motor you going to be in the up in the rev range anyway and thats were CAI's shines, above 5k+.

Benson or jimmy told you this , which they were told by dyno dave eh ? Lol.

Still , it's all food for thought.

All I know is there is 300+ dyno runs done on Insight Motorsports dyno testing intakes on B20/B18/B16a setups some of which the boys where involved the rest no one but Dave and Scott know about.

Honda got it right with the stock airbox and rubber intake arm :confused:

Anyways, lets hear more theories

All set-ups tuned on the dyno we have had different size piping and length to tune each motor. Some length's you cant fit in the engine bay, so there is give and take when its comes to the length

The blox filter combo has been one of the best filter tested against the big branded fliters

Jimmy told me that SRI would work better then CAI... BUT i was told me other b20 builders from the states aswell so ye...

Let's get some dyno sheets to back this up !



Although , would it be a general concensus that any particular type of intake will benefit a similar engine to a built b20 ? (ofcourse tuned)

you can compare the SRI to the CAI unless you are driving both on the road. When dynoing the bonnet will be up letting the hot engine bay air out and obviously the CAI will be restricted as it sits near the ground. The dyno's fans cant be compared to road air either.

Im using stock airbox and piping atm and I think it works great, just as good if not better than my SRI I had previously....

Heading back to costs for a sec.

Was quoted $320 for the complete bottom end from my local parts guys in Brisbane about an hour ago while picking up some other bits and pieces ;)

Also what would the average engineering/mod plating costs be for a displacement increase?
If anyone has an estimate that'd be great.
