Look, for once im somewhat agreeing with you, the numbers dont add up. 

But, the facts add up, its been clocked, we have seen the times, we have seen the MPH, we have seen the engine bay, we have no reason to actually not believe the hp figure, at the end of the day thats frOcking stout for an aspirated engine. 

The calculator Dave put up works off the same principle of the Moroso slide rule, hence Moroso HP. Moroso HP aint RWHP, its closer to FWHP, so the numbers come a lot closer to working....If the cars uber light....And it aint that easy to get a whole lot of weight out of a LC/LJ as there pretty slim to start with, so basically I recon old mates just done a good old fashioned frOcking good job at putting a freak together. 

 

Cheers.

Thank-you DJ, as calculators are just a figure in a perfect world.

 

This calculator is pretty close too:-

when you put in 1700 ( car/driver ), 10.32 seconds and 127 mph = 288.7 rwhp

I'm sure a few of you guys on here with your extensive knowledge and no end of expertise with anything holden six and torana related can put your noggins together and produce a 1000hp out of one of these engines naturally aspirated with ease,(I've read the super long winded responses to simple questions on here)....dunno what you're all waiting for?
You'd be surprised how much can actually get done if you separate yourself from your keyboard warrior status and enter your workshop for a while....just saying.

That's right Jason Mate,

 

Just need to remove/change parts weight,

 

to get the total weight to 773kg ( 1700 lbs ) including driver.  B)

 

dave its in pounds for this calculator

 

there may also be a better fuel type.

ok dave you are telling me that a lc torana with a driver weighs 773 kg?did you go to school dave?if my lj torana and my weight about 830 kg with turbo power i will be running quicker than victor bray down the 1/4 mile.you have your numbers wrong there old boy.stop drinking vb and start drinking lemonade.

That is a pretty quick 60ft, probably around 6.60 to the 1/8?

Did you see what harmonic damper he was running?

I'm not sure what balancer is on it, but it did have a trigger wheel bolted to front of it.

These times are extraordinarily impressive for N/A 202...

 

When I saw the footage earlier of this car- I presumed it had dugan/ jzed head...

 

Now seeing that its running a 9 port, I am simply amazed... By my reckoning the head must be flowing at least 400hp to achieve these times- which I did not think possible for a cast 9 port... I have heard some of the NC guys are getting 320hp or so flow but I dont figure this would be enough to push these times... Could be wrong though... The cast head has always been the major restriction for the old 202, hence I can only imagine this engine has some extraordinary head work to achieve these times... Or a sneaky sniff of n2o (not saying this car is doing this, just saying the sniff of nitrous can help overcome the restricted head by my reckoning)...

It's very tidy in there.

Very nice engine bay...

 

However, I am curious as to the mods on the firewall... It looks like the engine is set back about 200mm and the firewall has been cut to accomodate?

I would think to run a 1/4 like that with that engine the chassis must be set up extremely well. It gets down the track like a 6 cylinder pro stock car. did anyone notice one of those Brock energy polorisers tucked away in there. these blokes have certainly cracked it. I hope they keep their secrets for a while.

Regards

The calculator Dave put up works off the same principle of the Moroso slide rule, hence Moroso HP. Moroso HP aint RWHP, its closer to FWHP 

I could be wrong but I have always understood moroso to be rear wheel HP.

 

For example, I am looking at it now- a LJ torana with about 2600lb running 102mph, basically a low 13s car, gives me about 210hp (or say 260 or so flywheel hp). This equates to rwhp to me as if it was flywheel, I am guessing the rwhp would be about 160, which just doesn't seem right... 210rwhp may be a little on the high side for a 102mph car, but in my reckoning it is closer to the money than say 160-170rwhp.

 

Or another example, a 2600lb LJ running mid to high 12s and 106mph (basically an extremely strong cast headed 202, not many actually achieve these times) shows as a little under 240hp, which would be about 280-290hp at the fly... This to me would make sense as this is getting close to NC flywheel HP... there will be quicker 202s out there but not that many street type.

 

I could be wrong, and in reality the numbers are arbitary, but just floating it out there...

 

What are other thoughts? Curious to hear. Perhaps the moroso slide is less accurate with the little sixes?

You either run the numbers or you don't....call me old fashioned but you'll look like a real dick if you're claiming "x" amount of hp but getting no where near what you should run.
That's why so many people avoid the strip.

Need to buy a new slide rule, #@$^%& if i can find my old one. 

 

YOu could be right. 

 

Once i have my car on the strip and the dyno i'll do the slide and see what it gives, if the slide rule calculates hp low enough.
