What hp is needed to run a 10.3 in a full street trim xd falcon.

Racer · 02-20-2005, 16:09

About 600hp

600 hp is what i want. I wont stop to i achieve it.

Yeh about 600hp probably even less just depends on your setup I guess though suspension, stall size, ratios and tyre height all play a big part with mine its just come down to trial and error working out what works best, I had my rear leaf springs modified and it hooks up pretty well a 4 link with slightly wider tyres would have drasticly changed my E.T. i reckon with my current setup and the previous 125mph times its should do a low to mid 10 and mines aroun 570fwhp or so it works out to.

So true. The complete setup becomes vital when running those kind of times. The more efficient the setup, the less power you waste. What 60' are you running XD408?

Just found it else where - 1.58
Generally a car running thoses time would 60 foot well in the 1.4's, so theres a lot left in it yet!

Yeh exactly its just weird that i ran 11.36s on street tyres at 125mph on 28" tyres but i lost mph and did a quicker time on slicks (122mph) which were 28" tyres as well???

Does your timeslip have your times broken down into 330,660 & 1000ft? If so compare timeslips & you should b able to pinpoint why you lost MPH. Could be lots of mysterious reasons. Ahhh the joys of dragracing.

The more traction you have (which means lower 60's) the less mph you'll have. I've read that somewhere. Off the top of my head. I think it was in a 385 series engine forums where a lot of them are running 7's and 8 sec passes.

I dont beleive that. If you had a better 60 foot time, you would be revving more at the end of the 1/4, hence more mph. The only thing i can think of is your gear ratio was perfect for your 11.3, but with full revs before the end of the 1/4 made it lay down some from revving higher than ideal with the 10 second pass. Or a variance in the slicks for some reason from your 11 second outing to now.
