Sounds great man. Something i'd do after I get some carbies and other mods installed. My mechanic is an expert with holden 6's so my engine runs real smooth already.

Great stuff jabba, I know exactly what you mean. I took my hatchback (253 powered) to the dyno guy and it was running pretty crook. Less than 2 hours later it was running like a brand new car. Drives twice as nice now, feels better, smoother, and much stronger. He had the carby apart, changed jet sizes (it had been running lean), set the timing spot-on etc etc. Best money you can ever spend in my opinion. Makes all the difference.

Did you actually get any power readings from having it on the dyno?

Mine is a totally stock 253, stock everything, right down to the 2 barrel WW stromberg carby. Stock exhaust, the lot. It initally made around 70 kw at the wheels, and after the tune it made 85 or 88 kw from memory (can't remember which). He said that was actually pretty impressive power from a stocky.

All I'm gonna do is ditch the 2 barrel and put on a quaddy, and replace the points dizzy with an electronic. Will be interestig to see what difference that makes....

Bring the car over to Bodangora(Wellington) on Easter Sunday to the 1/8 th mile drags for some real "Dyno" results

Isn't 85kw atw pretty good for a std 253? When my brother had his 253 sle I never got the chance to play with,it sounded really sweet but it drank the most petrol out of all our cars & was one of the slowest but was funny doing wheelies in it in the rain with 2.60 gears in the diff.

Hey Brett, (LXCHEV)

I want to get my carb Dyno'd now seeing i got all my proper carby and stuff on there... Where is the place u get urs done and how much will it set me back?

I also really want to see wat power the 290 has!

[warrenm]

Yes I'll try and stir up a few. I'm part the way to being called a Toyota now that I have a Toyota box & diff. I'll need a bit of a stir up before I race the following Sunday at the Nostalgia meet at the WSID. You should take the tory to Naranderra & give it a run after getting to the finals at the Summer nationals.

Hey Warren, If your going to be at the nostalgias, Make sure you tap me on the shoulder if you see me.

Look for the big bastard bludging around Cliff's Back-in-Tine FED.

Cheers!

Keithy - 101kW at the treads from a 179 is very decent grunt mate! That's around 135HP you're putting down. My old heavily worked 202 with all the work and triple SU's still only made 100 rwkW, and that thing flew.

Obviously, different dyno's vary a little bit - but they still give a fairly good ballpark reading. So yeah, I think you're 179 is making some great power.

My dyno guy said stock 253's generally make anywhere from 60 to 90 rwkW, depending on condition etc. He said most he sees are around the 70 rwkW mark. My 253 is dead-stock, however it had apparently been fully rebuilt and freshened up only a few years ago, so I'm rapt with how it goes. Can't wait to get the Quaddy and elec dizzy on, and then play with the exhaust system (leaving the standard exhaust manifolds). I reckon I can get it up close to 100kw just with those mods.

[MRLXSS]

Yeah, i thought my old 253 went pretty good, i had a Crow Cam, Quaddy, Elec Dizz, Dual Exhaust (standard headers)... It went pretty good for what it was But this new motor i got does have a lot more power, hopefully i can get some extractors soon to breath more power to it!

[MRLXSS]

Whats your new motor 253ToranaSS??

My new motor is a Stroked 253 out to a 290, elec dizzy, Torker Manifold, Balanced and blueprinted. Stock Headers and dual exhaust. I think std Heads as well. So i think some L34 heads and some Extractors would do it hte world of good and give it a shitload more power!
