Upping torque on a 918 blade?
Hi Chaps
I am just buying my racing buggy ready for next year running in the Nora Supermoto championship. Very excited!
Anyway, it is running in the 900 class with a 918 blade engine with standard box and carbs. My question is, what is the best way to
'fettle' a little more grunt from this engine. Whats my best bang for buck whilst remaining with a smooth torquey power delivery?
Dynojet kit - whats the approx increases here?
Different air filter? Any noticeable improvement?
ECU (CDi) changes? Any worthwhile mods here?
Appreciate your advice.
Thanks
Harvey

I believe that a Dynojet kit INCLUDING filter is meant to give roughly 10% so if you couple that to a standard (ISH) blade output of 129 you get a
reasonable 142.
Stick on a decent exhaust might get you a few more brake (maybe) so at a push, maybe 145.
I have read (on here) recently that a CBR600R ECU would lift the rev limit to higher then the standard 11,750 of the 918 Blade, but I'm not
entirely sure I'd want to do that on a road car.
Obviously as your racing that doesn't matter so go for it!

Thanks Steve
I heard that too also potentially a slightly more responsive map, is that correct? Which CDi/ECU unit does it need to be? Does it need to be the
corresponding CBR600 to the corresponding CBR900 based on model year or is it no so sensitive as that?
Whats the best source for Dynajet kits and filters?
Thanks

Its probably worth giving Andy Bates a call at AB Performance. If there is anything to be gained from using a CBR600 ECU, then he'd probably
know about it along with spec/year you'd need.
He also sells dynojet kits.
He really does know his onions when it comes to all things 'Blade.
His phone no. is 01449 736633

No worries, here is the thread that I read it on and it looks like Hobbsy has one for sale so you may want to U2U him...

As for the jetting kit and filter I would recommend Andy Bates of ABPerformance. His number is 01449736633. He is fairly priced and gives great
service.
Cheers,
Steve
EDIT: I guess I should of refreshed before I typed all that!

Ultimate way to add torque is add a turbo!

LOL
I was actually going to respond with that myself last night Doug, but as he said he was racing it I assumed it wouldn't really be allowed - was
definitely what I was going to say though

A jetted and open filtered carbed blade with a decent exhaust system will put out about 135-140bhp absolute max, which equates to about 115 at the
wheels.
As others have said, speak to Andy. There's lots that can be done (cams, head work, big bore etc) its just a matter of cost.
Out of interest though, is a 919cc engine allowed in a 900cc class?

Hi Chris, its called the 900 class but you can run the 918/919 blade as the 'tweaked' they rules

I wonder if it effective to design some milder cams for it to increase bottem end at the cost of some top end.

Hi
I think I will be trying to keep the internals pretty much standard as I am not a cheque book racer!
I will also probably abuse the engines a bit so will likely have a spare to chuck in if (when) I lunch one!

Harvey
