How about a whole lot of displacement with some boost to go with it?
Oh wait Ive already been down that road! :woohoo:
Ill stay with the gpz1100 motor in the 750 frame idea,tons of power and still run it on pump gas

Without forced induction, a very well tuned 750 will make a MAXIMUM of about 50 lbft of torque. To get 100rwhp you would need a head and cam combination that would give you that peak torque at 10,500rpm. Not sure if it's even possible with a 2 valve/cyl head...

Here's a guy who already tried some of this and has real numbers oldskoolsuzuki.info/uk_lee/Thebikes/GPz/GPzDyno.htm

The dyno test he posted shows 67rwhp and 45lbft of torque. Looks like the engine made about 58hp in stock form and he ultimately got it to put out 72rwhp and 50 lbft using a head with bigger valves and bigger cams.

On the other hand, the 750 Turbo made about 90rwhp stock. Minor tweaking to boost pressure could get you over 100 easily. From there, sky's the limit. Here are some guys that know what they're doing with a 750 Turbo www.750turbo.com/fastones.htm

kz750が工場ジェットキットは私があなたにエアボックスと排気用のK＆Nフィルターを持つ別の8パーセントを与える見たと宣伝し、1980年に74馬力の定格され、ステージ3は高価な排気であなたに10〜15％の利益を得ることとなります74 X0.15でも90馬力にあなたを取得することはありませんポッドフィルター。
kz750 is factory rated of 74 horsepower in 1980 a jet kit advertised that I looked at will give you another 8 percent with a k&n filter for the airbox and an exhaust, a stage 3 will get you 10-15 percent gains with a expensive exhaust and pod filters which 74 x .15 will not even get you up to 90 horsepower.

A small kz head that flows 88cfm can produce 130hp.

A plain j head (not gpz) flows 84cfm stock and can produce upwards of 130hp

A 750cc head that flows what? 55 or 60 something cfm should allow 100hp?

Hey ask the elephant! NOt only he take out the garbage, he tells you how many shots

of nitrous you need as he bites through your tootsiepop.

Wire man brings nuclear weapon to squirt gun fight AGAIN! :woohoo:

ちょっとDEEZは、彼が彼の最後の名前の背面を望んでいると呼ばれる 83 gpz1100 puts out over 100 hp, I don't know where you got your numbers from but somebody should put you through college

And tracks are for racing, not streets.

Also do they even allow turbo bikes in the vintage race class? So i guess i wont hit 100hp. But how can i increase torque? The bike has pretty good pull coming out of a corner in 2nd or 3rd gear but top of 4th is where she just kind of levels off.

Like i said im building to to be a cafe racer, so light and manuverable with decent power. I dont like top speed i like the acceleration. So i guess i should of made the title, how to get 100 foot pounds of torque lol.

The problem with a turbo is turbo lag, its going to take a while for the turbo to kick in and when it does you may have to chase down your bike. I would definitely go with a blower if forced induction were my route.

Have you ever ridden a turbo bike? :whistle: :whistle:

This pic is 2.4 seconds after Nads' turbo kicked in.





8.4 seconds later, Nads had chased down and remounted the bike, to resume lead position and win the race!

Not just anybody is capable of performing such feat.

Good Fortune!
