996 Sps Power

Engine rebuild with hi compression pistons, blue print and balance bottom end, port heads ,poss new cams the list is endless really mate just depends on how much money you have to spend? ? or do what a lot of people are doing now and fit a 1098/1198 engine into your frame.

 

My SPS puts out 150 rwhp. Its as reliable as a rusty hand grenade.
As Cookster said above (and if your race series allows) I would go for a bigger engine. Same power and much better reliability.

 

My 998S (996R) is supposed to be about 150+ bhp, I guess it's a rear wheel?....
The motor went to Biggelaar special performance before I had it according to paperwork.

It has a before run 134ish bhp dyno (had been messed with already) and after.
I assume the stock bhp is measured at the rear wheel not the crank?
Are they are meant to make 130ish stock?.

Mine has defo had head work. From paperwork it looks to have had cams as some point... I don't know what's in it now as they took the slipper clutch out and it looks like someone put cam timing back to standard at some point.

It's not as strong as the stock bike low down, but mid range on it feels as strong as my fireblade 1000rr which is 150 ish peak rear wheel bhp. Of course the torque is a factor. It was geared 1 down, 2 up and I think they made it rev higher to get the top speed out of it..

I think my Ducati might struggle at top end but it might not be making that power now if it's been de tuned a little.
I don't ride it that hard on the road.

The map I have rev's to 14K... not sure what else they do to valves springs etc.

Not sure I'd want to be riding it like that, even racing but I guess it depends on the regs and how deep your wallet is.

I'd swap the motor out for a more powerful newer if I was racing and reg's permitted. Better in my opinion not to run a highly strung motor... first you have to finish.

I was going to tune and R1 motor that was in a chassis to make the same power as a newer gsxr, but to get stock GSXR power out of the older R1 motor, I was told it would need rebuilding after every event apparently circuit racing... and the slightly tuned gsxrs would still be quicker, so bit the bullet sold it and bought something with the gsxr engine... My GSXR1000K6 was making 200bhp at the crank and would last a whole season and some...

I guess my 998 motor (996R) had all the above, as is the norm with tuning.
It has a 54mm exhaust, 996R ecu, perhaps reflashed? and a PC3.
I understand you can't flash an ECU in realtime??
So much more time consuming than a PC3 for fueling, which can have inputs made while the road is moving. I am more familiar with power commanders, although reflashing obviously allows more parameters to be changed.

 

Stick the 1198 motor in there, 170hp and 92lbft, keep the SPS motor for when you sell it

 

Another option: have you considered shortening all the straights? :smileys:

 

Just curious: why do people fit these engines in the 916/996 frame rather than racing the 1098/1198?

 

Because they can and it's cool.

 

The bike is so much easier to work on for starters. And it still iconic

 

the earlier bikes are easier to work on as mentioned, still loads of parts on ebay, so i guess you get the best of both worlds, iconic bike of the 916 series and the power of the later bikes, makes sense to me.

 

What with the electronics if you put a 1098 engine in it?
I suppose you need to change a lot fitting all the parts in there?
Are the engine mountholes exactly the same?

 

Talk to @Nelson he's done a few conversions now and getting pretty good at them. If I remember you use the engine , dash, loom, ecu and key all from the 1098/1198. Or you can get something like motec or bazzaz engine management system which you can use but not cheap! !

 

My bike racing knowledge is limited, I've only been around a bit of international road racing.
I did look into club racing years ago... a class like pre-injection as an example, might permit open regs on tuning the oem motor but it won't allow a newer R6 motor (as it would not be injected in this case)

A old pre-injection bike would be hard work of that class and on the grid with modern 600cc bikes, so that would not be a consideration for me either.

Therefore, I can't imagine them allowing a bike with a motor 100 or 200cc bigger than stock with out it changing class or as in hill climb cars, perhaps a penalty?

If this Duke mod was permitted, I'd expect the grid not to restrict the age of the chassis? and in racing terms, if it's as serious as those I know, you'd be at a disadvantage, racing a older machine with a newer motor against a newer machines.

I guess it depends how good the other guys are?... I don't for one minute think I could beat some of the good road racers if I was riding the latest R1 and they were riding my old R6.

I'd do the mod as a road or track bike but I'd have to look at the racing regs closely if I was to it for racing...

If you race, competitively, surely you need to pick the right bit of kit... which might not be what your heart wants but if you do it for fun, that's different but to me personally that's not racing...

I do love the idea and if my 998 motor goes pop it will be a serious consideration for me.. I certain favor stock power for the normal road use over a race tuned engine, that's had cam's and increased rev limit.

 

Good luck next season, sounds like you have some decisions to make.

 

Imagine. Your simple little 996 not only our dragging on exit to a corner but also passing at the end of straights , on those badger blades and zx10's

 

I got asked a few questions in the garages last year...:Angelic:

 

On pitwall Anglesey last year. Mike on his yellow shed 748. Open class race. Fella says 'lovely bikes those Ducatis, but watch that fireblade leave it behind now' to his young mate.

Mike powers up the hill, passes two litre bikes into the hairpin.

'wow! Those 748's are faster than I thought!!'
