I'm sorry, but that's a load of bollocks. Where can I get some of that sh!t you're smoking?

Home grow.... Anyway, Guy's I kid you not.... Don't believe me, how bout come to the Next Improved production race @ eastern creek, Oran or Wakefield? or for you 7M, when the next round of the national IP racing is up there next, head straight for Leanne Ferrier's RX7, the one wasting the rest of the field buddy... Speak to the Guys: Dave flood aka ex Dynotrak, Redline motorsport, and has been based at priemier auto down here for the last month, just before the last dyno day, that's him in the driver seat (see pic)

Dave loftus, the blue starlet, dyno day 3 on display, also for you young'ns, it was featured in a very early Zoom (something like issue 4 or 5). This was engine,

sorry only engine Pic this was his bog stocker 88kw version, as featured in Zoom, the 110kw was the one he ran at Phillip island last year and set class record, and the newy (150kw-170kw) was running at the begining of this year and a more wilder version he's developing is in the pipeline. Finally, Abes, the guy that built/building the high output versions and any many more winning race engines. they don't bite unless someone poke sticks? well how bout it? three of the best in the racing business, with over five years getting a 20V to that point.... And I can tell you not many have got 20V to this point! A 20V's are very new and require a very different amount of logic put into them. These guy's have seem to have figured a few things out, which other are still chasing and the results show.
Besides...http://www.toymods.org.au/records.html results are results, let see how it goes next time!

nothing better than pullin away from a 20v when u only got 50kw

sorry dude, that's torque not power in play there. I use to do that with a 7A! And my Rally version spits them out for dinner all the way to 200KPH!!
see Nark know's the jist:

Traffic light GP:
GZE. 20V has trouble keeping the 16Vs off its tail in general day to day driving.

Track:
20V. Roles are reversed with the GZEs having trouble keeping the 16Vs off their tail.

That's a perfect explaination of torque vs power! I think you've got that saved somewhere by now Laughing

You do know a stock WRX has about 98AWKW don't you? Werent you the one that the dyno operaters scratched there heads about?

Don't be a dyno queen and quote stupid dyno numbers that are just in plan error, go run down the qtr and show us the MPH.

Sorry to inform you there, BUT NO I WASN'T THERE! I stopped over to see Dave about something else when he told me the results 2 days later!! Shocked

and many things do play a role in bloody 1/4 times, (let's talk track time's? that my goal!) one thing I'd like to know, how much torque did the dam thing have? bet you F/A which = poor 1/4 times. Stock WRX 98 KW 230NM vs 120Kw 100NM, I know straight away who'll win.... both car weigh about the same.

gee now its driberling isnt it TRD S Africa spent heaps on both the 20v engines and could only get 185 hp and that was the blacktop 1 and thats at the fly wheel and its not kws

If that's the RSi rally car, there aiming for a high torque and moderate power (185= 138kw), so you can't have both, but then again, the B/T head design and internals are nowhere as good as the S/T, So that's why I've decided to use the B/T throttle, flywheel and crank, with S/T head, and A/M rods and pistons. So if I end up that power and 250+nm I'd be wrapped!

Quote:

my mates black top makes 87 kws at the back wheels so thats about right

That's about right with a stock ECU. But I can confirm that til the G/friends Bitsa is in and running, but if 87Kw is true, I'd expect less as Abe has stolen all the goodies for my engine Very Happy

Hey Guys, I just thought id put in my 2 cents worth. Last year I bought a Silver Top 20 Valve engine from a bloke who raced dirt buggies. He also had another silver top 20 valve which he had taken out the buggy there.It had spun a bearing in the motor but told me that this had Ross forged pistons(BIG DOLLARS!), port & polished head and port matched throttle bodies and 304 degree TRD cams.

Should of done his research, Abe's running that kind of gear in my newy,(about $4K worth) but 304 cams are way to big for the application I have in mind (Rally), question, did he have the VVT-i running? would've like to known the C/R....
