Bike engines with over 100bhp
CraigJ - 4/3/07 at 07:35 PM

Right ive finally decided what im going to be building. Its an Onyx Mongoose, im going to grimsby on tuesday to have a look at there cars and to leave a deposit then will be picking it up in about two weeks.

Instead of going with the K series lump which the Mongoose is normally fitted with im going fo a bike engine but i dont need that higher power like R1, busa etc. The Weight will be under 400kgs hopefully around 370-380kgs. Im only going to have around 500-600 to spend on the engine and it needs the carbs wiring with it.

What options if any do i have?

cbr1000f or zzr1100 both lardy but in your budget , cant see you getting under 450kg using them though

This one would be perfect but be quick

The mongoose with the K series only weighed in at about 440kgs so going the bike route should save a fair bit or weight

I'd definitely recommend the CBR1000F. Its cheap (circa £300 quid), strong with bags of torgue and is good for 130bhp.

As to weight.....my Striker is only 398Kg (without myself of course!)

zx9 or blade both fit the bill.

Early blade no need to worry about emissions should be in price range


Hellfire - 4/3/07 at 08:54 PM

Just a little advice... it's not exactly the power you need to contend with. It's the weight which the engine will need to deal with being as it's fitted inside a very heavy bike (i.e. CAR). The smaller engines will not have the internal strength in either the gearbox or clutch.

Therefore a larger engine even though it has the power will be more suited...

steves right you need anything over the 893cc blade engine

I will put my hand up for the water-cooled Suzuki GSXR1100.

Grunty (~140bhp in bike) and cheap (maybe £400). Supposedly very tunable. Get one pre-94 and avoid the requirement for a catalyst and all that joy at SVA.


In the East-West orientation they are well proven in side-cars & hill-climb stuff.

Downsides, 5-speed. A bit heavier than R1's. Not common.

I have no direct evidence that they work great, but I like the theory and I have one in my shed!
