Power from a 3/2T-G Hybrid in TA22???

[pro_k]

Theres something wrong with the set up for sure.

Change your timing belt

Check that your carbies are running properly

Your running standard cams? You will need to change cams to make the most of this set up. Make sure you dial them in.

You should have at least 70rwkw. My 3TG is a little bit more worked and it achieved 99rwkw the last time it was on a Dyno.

It should be a lot more fun once you get sorted.

What mods have you got? every little bit makes every difference.

And I went and got a print-out this morning.... "Whoopdedoo what does it all mean, Basil"? (quote Austin Powers)

Dana,

Those air filters look almost identical to the Lynx Redline Items. They will be better than any of the foam type filters just not as good as the K&N. The K&N filters an be ordered from any decent performance workshop or parts outlet but they won't be cheap. The complete assembly is part number KN56-1310 and you will need 2 of course. I could order them for you but postage will probably make them cheaper locally. They would be $109.80each oplus postage. The ones you have do work so maybe keep them in mind for later.

I'd be getting new timing chains and changing that flywheel before worrying about the air filters.

Keep in mind if you do change the cams then new valve springs is a VERY good idea and they are a cheap purchase from performance springs who sponsor Toymods Setting the shims for the new cams can be a very time consuming job and you may need new shims. The time to do it of course would be while the timing chain was already off

Pro K,

What Dyno was used and what has been done to your Hybrid ? A figure of 99rwkw is possible but uncommon. And 70rwkw form a stock head/cam'd 2/3TG is unheard of which tends to suggest your quoted power figures are about as accurate as your Timing belt !

I'd be pretty bloody disappointed with that. That said, to really be able to compare it with anything else (I mean, look at Rona's), was it a Dyno Dynamics dyno done in Shootout mode?

Mine was on a Dyno Dynamics dyno, that being said the tuner did state his dyno does read lower than others.

if your timing chain is slipping, id be suspicious that your cam timing is probably out enough to cause a drop in power like that... get new timing chain kit and degree in your cams

[sillycar chick]

Hmmm maybe I will stick with the air filters I have for a while

And its going to cost me $500 for new timing chains and guides - thats parts only - so I think changing cams isnt on the cards just yet.

Rod, another Q is it true some of the different 2T-Gs came out with different cams and head combinations (like different porting)?? I would be interested to see the differences between all of these. Mine is an 88261.

[Rodger]

I say that dyno sheet is very typical of these motors running stock cams.

Torque- the lower trace is good, nice and flat. This line is an indication of how well it drives as Rod is saying and yourself is saying about how nice it is to drive.

The top trace is power. Just as we have been saying- the power rolls off big time after 5500rpm and is exactly what the stock cams give.

The Motor is simply running out of air. The cams cannot provide enough opening/duration at those revs.

The T series motors built like mine have cams which breath better up high and carbies tuned to match the higher fuel/air requirement. These power curves then keep climbing and as for mine it rolls out about 7000rpm.

I can get ram tubes in red or blue or natural alloy for $40 each. Anything to lengthen the total intake tract will boost the midrange torque some more also.

Dont be discouraged though. A lighter flywheel and some mild cams 270/280 duration will light up the power and still make it nice and drivable.

You have got yourself a good strong combination that with a few more tweaks will unleash that power to reach the goal.

Yes there are differences between the 2TG heads. For your engine the one you have would be the best in my opinion.

The 261 cams are not the most aggressive but to be honest I have yet to do a comparison of the varying cam durations between the models. I have my theories but they are only that at this stage.

Do you really need new Timing Guides ? New chains should cost you less than $100.

[sillycar chick]

Thanks Rodger, that makes a lotta sense. Dad was wondering the other night if you can get slightly bigger venturis for these carbs?

Yeah, they are F**KED!! They have pretty big chunks out of them, not like clean wear marks but really bad gouges. I didnt replace them at the time cos I never knew where to get them, but since then someone has put me onto a place that has them in stock. Expensive, I know, but if they last 20-30 years normally, its not that bad, cos I wont ever have to worry about them for another 20-30 years, and by then the laws might not even let TA22s on the road!!

Toyman - Meant to say chain! And yes it is possible to get this power figure! I have heard of a rally guy in Canberra who has around 110rwkw - This is the highest figure I have heard of.

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.

[Rodger]

There are bigger outer venturies available.

The other trick with those S5 Solexes is to remove the sleeve that sits in each bore, before the inner venturi.

Problem with doing this is it takes away some of the midrange torque as the air now moves slower at these revs.

It means however that the motor breathes better up high as more volume of air is able to be drawn in.

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

Well there is where the power is coming from!! Makes it hard to compare with my stocko engine
And having it balanced makes all the difference with your rpm and inertia inside the engine, and double valve springs help things along as well. And customer made extractors? They are probably made for better flow as well Wouldnt mind your engine, sounds pretty good.

the ta22 could be running electrically *shudder* in 30 years...

im suprised how expensive that timing chain kit is, has anyone else replaced their guides/chain recently?

plus get some warmer cams, would really compliment that motor.
