[N/A-PWR]

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.

The truth hurts man, I'm off to the shed...

I wonder what lightweight and sticky tyres they are using too?

 

gets a quick launch for spooling up.

Atleast you go in the shed Jonesy!

Atleast we try Rob,

 

Where are all the dumb ass questions from the rocket scientists?

More results....less dribble,c'mon you legends can do it.

That's right Jason Mate,

 

Just need to remove/change parts weight,

 

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

 

dave its in pounds for this calculator

 

there may also be a better fuel type.

[N/A-PWR]

No worries Jason. 

 

you have your numbers wrong there old boy.stop drinking vb and start drinking lemonade.

Anyone know what is the 60ft time and half track time?

The time card I seen was 1.40 something 60'.

[greens nice]

The time card I seen was 1.40 something 60'.

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)...

[LC-GTR-1969]

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?

[LC-GTR-1969]

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?

[hip6]

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.
