Thanks for that. I'm just setting off to work now, so a few weeks to look into it then order some once I'm back.
 
Should have told me about that 3d printing have a year ago, Neil! :D
We had one for our company and modelling and printing was my job!

But I still work with 3dsmax at home, if you want I could model you some nice caps so you don't have to mess with Sketchup!? ;)
 
Frankendini is alive :mrgreen: Brain transplant complete and it starts and runs without a christmas tree dash, using a Specialised Components ECU and adaptor wiring loom.


Next stop, Leeds and a stay with RS Tunning to fit and map the bodies. Bring on the noise :twisted:
 
To quote the great philosophers rizzle kicks "let's get down with the trumpets" I seriously cannot wait to hear these :0
 
New clutch and thinking about forged internals would be my bet surely she can't take much more power

Then a machine gun?



Suppose that effect may be done with a rev limiter though...

Neil when's your limit? Will you ever stop?

Theres a boosted K4M clio running 180 on a standard bottom end. He has bent rods with higher boost going above 200 but the torque would have been higher than NA.

MSA B license and a couple of sprints/hillclimbs could be on the cards. Its not going to be a full on stripped out track slag :eek:


I haven't been able to watch it due to the rig internet, but Simon from SC sent me this link.

Ah right maybe I will be alright getting a 100 shot then because that'll leave me on about 185ish ponies which will hopefully be safe
 
:eek: everything still functional even with a new ECU to unlock the full potential of the engine even more i do like that :D , now just wait for the throttle bodies to fit in and lets hear that :p

btw neil is that the dephaser pulley or something that's rattling on stationary :s cause i hear it on mine also but on yours it seems loud or is it cause of the cam audio feed ?

Progressively controlled, maybe. You would also have to look into (measure) how much reserve capacity the fuel system has...

Obviously you don't want the engine to run lean, which is the usual reason for melted Nos fuelled motors. So, you need your fuel pump/regulator to be able to reliably supply enough fuel and have a bit spare. This may dictate the jetting (shot) that is realistically usable to less than you hoped.

If you can get a 100 shot (based on fuel avaliability), adding it in one hit whilst the engine is still at a relatively low rpm will produce a very high cylinder pressure. Big bang with rapidly expanding gasses with a slowly descending piston would put a lot of stress on the engine as a whole, as well as the drive train. Adding a progressive controller would allow the addition to be gradually increased as the revs allow. You can also tie in safety features like fuel pressure switches to cut the Nos if the fuel pressure drops and, bottle pressure switches to do the same if the bottle pressure is too high, so vastly reducing the chances of inadvertently running lean.

A bottle heater whilst not essential or even needed means after a few minutes warming, the bottle pressure is always going to be quite high. This reduces the chance of you jetting the system perfectly then, the sun heating the bottle and increasing the pressure, throwing the mixture lean :(

I think the best advice is start off small and work up as required. A set of jets isn't much compared to a bent conrod.
I was looking at a 50 shot.

Pass. I haven't and can't watch the vid to hear. I know its not quiet anyway. A relatively noisy engine anyway, with solid mounts, high lift cams etc probably dont lend themselves to it being quiet

Yeah that's true I suppose it's something to build up to in the end it's only £12 for a different size jet anyway :)

Next step after the trip to RS Tuning.

Permanent removal of westy and go kart from the garage :)
