Comes down to a compromise. I'd remove the sleeves and add as long a ram tube as possible.

What venturies are avail, do you have any, if so how much? I dont really want to compromise the torque I have at the moment, I need it to make up for the power I am lacking.

I WONT LET THEM DO IT!!! Cant stand these electric cars, there is no sound!! its too eerie, and nicely powered cars are USUALLY associated with lotsa NOISE!!! (with the exception of mine, which makes losta noise and not a great deal of power

)

Thanks Rinmax, I know they have to be all set up properly again with the new shims between the valve and cup, but how long does this really take????

Well, for someone that is experianced I'm sure it can be done a lot quicker, but it basicly killed a full weekend for me. All I did was measure the gap, record and calculate, then reinstall the camshaft. I lost count of how many times I put the cams in and out. I spent probably 18 hours that weekend just fiddling with the cams and shims. In the end I had to make modify some shims from a different engine as I didn't have the sizes I needed. So alot of that time is down to fabrication. But damn I'm not in any hurry to go down that road again.

Sillycar & Toyman - Whilst I didnt build this engine the basic specs are as follows -

3T crank
Bored
11.1 Ross Forged pistons
Fully Balanced Internals
Wade Cams 288Deg
Twin 45mm Webers
Mildly ported head
Genuine Toyota Valves
Gemini Double valve springs
Custom Made Mandrel bent extractors
2" Mandrel Exhaust

This engine is in a rally car, however it is very driveable on road.

Engine is going to have a freshen up soon therefore we will try to get a little more out of it. Shall let you know if interested.

Pro K,

Keep us informed of how the rebuild goes and I would be interested to know what size bore you are running.

At 11:1 Comp Ratio it should be nice and responsive even with the bigger cams. Do you run it on pump gas ?

I wasn't suggestingthe 99kw was inaccurate, Just the 70rwkw from a basically stock hybrid.

Looking at your Dyno graph it sure was running on the lean side of things in the top end.

Do you mean lean as in to do with the carby as in maybe in need bigger secondary jets or something? Or its just lean on the power, as in I probably need some decent cams?

Dana,

I was refearing to ProK's Dyno graph. The lower "curve" on his graph is not torque like yours but his Air Fuel Ratio. You can see via the left hand side of the graph that the number of his AFR rises with RPM indication his fuel system or carbies state of tune is not sufficient for his engine. the higher the AFR number the leaner the engine.

A lean burn does produce more power up to a point but as it also burns hotter it can do allot of damage to an engine.

Your graph does not show your AFR so I have no idea how it is but no respectable engine tuner would let it leave running lean and not warn you.

Toyman - Shall let you know if and when we develop it any further. I am more than happy with its performance, however as always would like to get a little more out of it without sacrificing torque.

Bore - 89mm

Run on Synergy 8000 - which I have found to be the best.

Yes it does run lean up the top, however on the safe side of lean...Will need to go EFI to have precise control. Still like the sound of webers too much!

Engine has lasted 26 rallies so far with constant abuse! They really are a great/tough motor.

Btw - Maybe my estimation was probably a little too high for a standard 3TG however it should have more than 70rwhp.
