Supercharged Bike engine

[sam919]

Hi,

Has anyone had any experience of supercharging Busa and ZX14 engines to around 300 reliable bhp?What sort of charger, engine mods to deal with power increase etc, i have had a look at TTS's site.

Thanks

Thats quite a bit of setting up. Unfortunatly the garage is fully loaded at the mo, just sold the fury. Looking at something for next year now, the GT-R from spire is going to have a ZX lump in it according to the website.
What sort of budget did you set yourself for the engine alone, do you think there are areas that might not be needed in the spec if only looking for 300hp. How much does the rush weigh?

Thanks

Turbo charging seems to be the cheaper option going by Holeshot racings prices. Supercharging seems to be is slightly more expensive.

The choice between the two is going to have to be supercharging as the smoother the drive the more consistent the lap time. The low down torque will also be an advantage on the tracks i usually race, top end wise the torque factor will fit in with adjusting outside tyre diameter or gear ratios.

Thanks for your comments

well!! five years down the line, i didnt get a forced induction engine and went for a NA duratec with 300bhp! its had three re-builds in 8 hours use and now i'm back looking at SC/TC engines again but more biased toward the turbo side, mainly due to using a bike engine and keeping the weight down.....having said that i have been offered a Big CC pro-charger by someone, so im back to square one! i sent Big CC and email the other day after a phone call with him (Sean) but have heard nothing back with regards to a breakdown in costs but 10 g is a figure that keeps popping up!

Anyway, garage to get built so it wont happen quickly, but ill post up my results which hopefully this time will be in physical form!

If anyone has any ideas or experience over the last few years on this subject i'd be interested to hear them.

I built a Turbo busa engine for my old Westfield.

Was running about 1bar of boost at circa 300BHP.

Power delivery was great, if you have a few revs showing on the tacho it just felt like a big engine.

I looked at the supercharger route and went turbo.

As some people have said it will cost 3 times as much as you think !!!

That seems to be the case, turbo lag being minimal, i dont think it will be an issue. Just gagging to get started!!
