Hi all, what do you think she will do as far as Horsepower at the flywheel and quater mile times, here are the specs:
LX Torana, weight about 1275 kg
tri matic trans, rebuilt, stall upped to about 1800 - 1900 rpm
3.08 single spinner diff, rebuilt.
308, 30 thou, standard stroke, electronic dissy, HQ heads mild porting (cleanup) standard valve size, roller rockers, Edelbrock performer, rochester carby, extractors, 737 waggott cam, running 14 inch hotwires on 225/65/14 tyres.
What HP do you think she will make and what would that combo be good for down the quarter??
Interested to hear what you experts suggest.
Power and quarter mile time estimate for 308

Thanks for your inputguys, Its not being built for big HP and quarter mile times, I was just interested to hear what realistic figures might be.
Cheers.

My UC makes about 200rwhp on a dyno. I dont know the exact specs of the engine but I assume it is standard stroke, mild cam, edelbrock 575cfm, maxitork mani, extractors. Heads are stock HQ. Standard Trimatic with standard stall. 4.11 9 inch.
There is a calculator here to work out an ET under perfect conditions. The weight is in pounds so you will need to convert that first. 1275kg plus 100kg (me) = 3031 pounds. The ET given was 14.41.
The only way to get the real figure is to take it to the track but so far the estimates above are on the money.

250 flywheel horsepower gives me 14.11 in a 3040 pound car! Do you think it might be 1 second generous? Tony has your car done a time down the quarter?

Nah, I havnt raced it yet mate. But if my stock 1.6 litre manual vvti corolla can do a 16sec pass I cant see the Torana being only 1 sec slower......
Like the calculator says, the figure is based on a perfect pass and allows for a 17% loss of power through the driveline to get to a rwhp figure. There are a lot of variables and I certainly wouldnt expect my car to run a mid 14 straight off the bat. I would be happy with and would fully expect a 15 myself.
