214 HP and rising.

[Kickaha]

In F1 it was reckoned that a turbo'ed 1.5 litre was equivalent to 3 litres N/A.
Which we all know was bullshit, it was more like 9 litres.

About 1hp per cc in qualifying trim

We got a crappy old Quad sitting at work with a Hayabusa turbo motor at the moment it's only got about 400hp

I sense a lifespan of less the 5000km

Why? does it belong to Dover?

[Sensei]

Have a Rapid mag with a 500 RWHP Busha in it & still not running the Nitro yet ??

[DingDong]

I'm thinking of the $$$, K4/headers/tanks/Turbo/tuning/+++/ & many mods to fairing to make it all stick and still look like a K4 at the end.

Brave indeed...

Update us on the next run

[aff-man]

depends on space etc etc..

Hey buggy i am not to sure if you got enough room under your hood for a turbo...

But in saying that turbo'sing that older zx6 you got lying around would not be a bad idea cause of all the mods it already has

[myvice]

Why mess about?
Nick the loud bit off the cop helicopter and tape it in ya frame!

That’s some impressive power to get out of a 1lt engine, I wonder what nos would do?

[WINJA]

given that all normally aspirated vehicles run a vacum rather than positive presure and so do alot of forced induction vehilces...I would be really interested how you came up with that figure....and more interested how it is relivant...as horse power is generated out of an engines ability to flow air...the volume of air... the PSi or bar figures crap people wank on about is as meaning less to a engines performance as steak is to a horse... all it seems to do is give boi racers something to talk about...

GIVEN THAT THE ATMOSPHERE WE ARE IN RIGHT NOW (IM AT SEA LEVEL) IS ABOUT 14.7 PSI ABS OR 0 GAUGE WE THEN SAY THAT AT 14.7ABS PSI OR 29.4 PSI GAUGE YOUVE EFFECTIVELY DOUBLED THE CAPACITY OF THE ENGINE , THIS IS CALCULATED WITH NO PREASURE DROP FROM ATMOSPHERE TO COMBUSTION CHAMBER BUT ITS BALL PARK .
HOPE ITS GOT A SHOW OFF VALVE FITTED PISHHHHH PISHHHHHHHH

there's a dude in the states who's stuck 2 turbos on his 03 636. oh yeah, it can be done. There's a dozen turboed 636s in the states. Most of the bikes can be turboed, and most have been done. Just gotta look.

I was just gonna do a small light pressure one. That way, you don't have to worry about intercoolers etc, and it won't be so hard on the engine. But still give enough kick to go 12 O'clock in 3rd off the throttle

[Mental Trousers]

Lou, was it running avgas or somethingelse exotic or pump fuel??

6lbs would be reliable as provided bearings etc have been taken care of.

As winja said.

As a rule of thumb, assuming 100% efficiency (i.e, ideal situation), for every 1 bar (= 16psi? not sure what the exchange rate is between psi and bar) of forced induction roughly equals to doubling the engine capacity.

Also, Spec-sheet compression ratio figures are compiled based on the volume of combustion chamber when piston is down against the volume of the chamber when piston is up. However, to see how forced-induction can affect the engine performance you will need to see the compression ratio from a different angle. If you compare the volume AND density of air (mixed with fuel) between piston-down and piston-up, it will not be the same figure anymore.
The volumes of those two situations may still be the same. But, the pressure (now twice the pressure from original engine) is now doubled and therefore I can say that compression-ratio for this engine has doubled. For example, what originally was 11:1 now has become 22:1. Yes, psi/bar figure relates to horsepower like steak to a horse.....if you like horse steak. And they actually do Horse steak in Asian countries where cows are expensive.
Disclaimer: this is only my way of explaining how denser air relates to higher horsepower, and is in no way an official way of explaining compression ratio. So you will not see any 22:1 compression ratio out there on any working bike engine.

Given that there will be engineering compromises (ignition retarding, lower compression, etc) and non-ideal situations (frictions, engine inefficiency, etc) then you might be looking at 60-75 percent increase instead of 100 percent.

So, at 18psi you can make the 1k will be quite like GSXR2100.
But, the power will not be 2.1 times the original.

That is if the engine does not blow up first. Those water jacket rupture can kill pistons very quickly.

If it is me, I wouldn't worry about the power so much. I would definitely get the Pishhh valve first! Turbo is all about fashion statement.

More details.
It's running a GT28 turbo, no intercooler. Power stayed at 214, torque was 105 lb/ft at 8000 rpm. It's running straight pump gas.

[bugjuice]

was the exhaust being dumped straight from the turbo, or was it using the stock/AM pipe out the back like there's nothing there? And where's the air being drawn from? Did you see?

[ducatilover]

if it has standard compression ratio... it would be far to risky to run 18lbs... detination would almost be certain...

yup, i have a mate in wellywood that kept the standard head gasket on his familia gtx whilst fitting a turbo that had the ability to push 25lbs through that little piece of shit, and geuss what happened?

[ducatilover]

At full throttle a naturally aspirated engine still has a slight vacuum.
In contrast, a forced induction engine has a positive pressure in the intake, in this case 6 psi. Or nearly half as much again as N/A
In effect this increases the capacity of the engine, which is why motorsport has a multiplier formula to maintain parity with N/A engines.
In F1 it was reckoned that a turbo'ed 1.5 litre was equivalent to 3 litres N/A.
Which we all know was bullshit, it was more like 9 litres.

there is no "equvilant" is there? what about the old brm v16s? n/a engines that had a capacity of 1500 or 1600cc [cant remeber but i think its the latter] and producing about 600hp at some extreme rpm.. the only problem was the ignition couldnt cope with producing the right amount of sparks..

good mag that! i have a few of them

I didn't get a close look. But it's hard to tell from stock.
