Still not convinced as other graphs i looked at arn't producing them gains.
And that link is from the manufacturer of that manifold so it could be biased as a selling point.
If n/a tuning was that easy and cheap everyone would be doing it.
Also honda exhausts are really restrictive so i don't see how a manifold alone can get exhaust gases out that quick and produce that much power on an oem set up.
I baybe wrong. Just not convinced
Hello every one thought I would let you guys know a little bit about Bisimoto Engineering since we have been brought up quit a bit in this topic. Our company has spent many years in developing parts for the F-series non-vtec Honda motor for our race program Honda Pro-Allmotor Insight. Our engineers designed many parts from piston design, custom profiles for camshafts, cylinder head porting and of course Header design. With this achieved the Bisimoto Insight produces nearly 500whp naturally aspired and holds records for the quickest fwd all-motor uni-body chassis, worlds fastest mph all-motor fwd, highest hp all motor sohc with quickest elapse time of 9.38 @150mph 1/4 mile.
From all this engineering and design we took the time to share with the public as well. The Bisimoto V2 headers do not come in one standard size like many other companies do. After placing an order with Bisimoto we will have you fill a complete specification sheet of your C/R, bore, stroke, usable RPM range and so on in order for our engineers to design a header specific to your setup to extract the most power and efficiency out of your setup. Using this method and design for our customers we now hold records with the Bisimoto header as follows:
Records under Bisimoto Engineering header designs:
World's Fastest and Quickest B-series Pro: 9.7et, on Bisimoto Header
World's Fastest and Quickest B-series Street: 10.4et, on Bisimoto Header
World's Fastest and Quickest H-series Street: 9.98et, on Bisimoto Header design
World's Fastest and Quickest F-series Pro: 9.3et, on Bisimoto Header
World's Fastest and Quickest D-series Pro: 10.7et, on Bisimoto Header
World's Fastest all motor car: 152mph: on Bisimoto header
