how many kW is an impressive amount for a car runnin a 202 red
I'd be very impressed with a 328Kw 202.lol.
Why would you want to measure a 202 in KW anyway ? that is best if you have an electronic engine, a classic 202 is more about the HP

Jeez, how long is a piece of string...?!?
O.k. then, without discussing forced induction or rare, monstrous drag/speedway/trackracing freak motors, here's a couple of simple reference points.
1. Street Machine magazine's performance project with a 3.3 Blue was to get to 200bhp (approx 150kw). They ended up about 5-10kw shy from memory....
2. I suppose with equivalent induction & ancilliary mods to a 202 red, you could say that 160hp/120kw would be pretty impressive - compared to most of the cars that have been punted about for decades with a 202 Red under the hood.
Then again, compared to just about any other 6cyl performance motor around the world in 1972, an XU1 motor would've impressed anybody! Even without tuned-length extractors or electronic ignition it must have put out something like 140-150kw in today's currency.
I'm sure the more technically experienced OldHoldeners here will give you exact XU1 performance specs.

'i'm definately shore that guage wont work with my tuff bango diff and Opal sydcrome box,if it goes though my grill,and I put the breaks on I realize its better with the glimer belt & tunned holly and Ederbrock duel feul webber gaurds, wiht etc primmer.'
From memory they ended up 10kw short with a 500 Holley... When they fitted the VK EFI and dyno tuned it, they got an extra 15kw or so at the wheels. That would be roughly 20kw at the fly, so they probably would have had over 160kw; it added up to a 14sec quarter in a 1250kg car. That is fairly impressive even by today's new car standards. Given that it was intended to be a street driven motor and it had all ports on one side, pushrods and mostly 45yo tech, that is very, very impressive. To put it all into perspective, down the quarter mile it was only a few tenths behind a Honda NSX.
My 186 red powered EH ran 96.6rwhp@5500rpm on the dyno, but factor in heat soak and that turns into an easy 100rwhp. Then factor in I had the solid belt fan on it, standard rockers (not roller rockers, I just bought some YT ones to go on), the plug gaps are too small and I later found out it was only getting 3/4 throttle. Working it all out (and going by the butt dyno after I half fixed the throttle problem), I reckon I could have an easy 130-140rwhp@6000rpm odd, which equates to roughly 120-130kw at the fly. Considering the car weighs 1200kg, it can actually outrun near-new Commodores and Falcons if you drive it right, even with the 3.08 diff. Remember that this is a 186, not a 202... :D
As for XU-1 specs, from memory they are as follows;
LC 186 - 119kw, around 280Nm
Early LJ 202 - 140kw, I think torque was around 300Nm
Late/Bathurst LJ 202 - 160kw, would have been well over 300Nm
All these were running points dizzys, cast headers, belt fans and 9 port heads - with EFI, a 12 port head, regraphed HEI dizzy, tuned extractors and thermo fans I reckon you could have up to and maybe over 180kw from the late LJ motor, now wouldn't that be fun? ;P

A few years ago there was a dragster at the local drag strip ( willowbank) that had a 202 in it and it ran 7 second passes all day long, can't find the info I had on it though, I'm still looking for it, Lindsay.
It wasn't [http://www.jzedholde...|this] one by any chance was it?
hi if you read couple days ago in my post mine made 110 kws at wheels with webers and hydralic cam not sure what that would be at the flywheel someone els would know.
Depending on what gearbox and diff you've got, you're looking at somewhere between 135-145kw at the flywheel. Definitely not too shabby. :)
I kno the Hi Comp red 202's came out with 101kw/135hp stock. if it helps
VK EFIs had 106Kw.
Yeah mate thats the link I was hoping to find--DOH!!
This is from a article I once read about a red motor powered dragster.
These are the specs
6 cyl red, Nine port big valve head, Comp of 11.2:1, 1 3/4 Su's, extractors, 308 deg cam.
It made 210HP @ 4750 rpm and 190 lb-ft 4500-5500 rpm
They then tried a few things.
Waggot Solid cam E3 set at 22 thou produced a extra 12 hp so now 222hp and a extra 15 lb-ft of torque up to a total of 205 lb-ft of torque from 3000-5000 rpm.
They changed the tappet clearance to 10 thou and achieved
236HP at 5250 rpm and 219 lb-ft of torque from 3500-5380 rpm
They then fitted ram tubes and it produced slightly more torque.
They then fitted a HEI dissy with 37 deg of timing and a total adv of 24 deg at 3100 rpm.
Swapped the extractors for stock XU1 cast iron port matched manifolds with twin pipes and running megaphones and a tip was to paint the pipes and cut them off where the paint stops burning off.
This lot gained them 9HP and a huge 42 lb-ft of torque from 2500 rpm.
It then ran a 10.5 ET of the trailer.
The only problem with comparing HP figures is that most dynos do not end up with the same output figures as each other and even the same dyno can have slightly different results day to day.
Also not all car manufactures calculate there figures the same way either and they also did tend to under estimate output figures to save any legal issues if a engine did not produce the promised outputs.
To be 100% accurate in a comparison you would have to run all the engines on the same dyno on the same day.
But with any engine if you are making 1 HP per cubic inch naturally aspirated you are doing well.

Also older power figures can tend to be a bit overzealous as they got their numbers using a different standard. So when they say the official figures for a XU-1 is 119kw it's probably more like 105-110kw and the X2 official number is 108kw, while that actual figure is probably below 100kw.
