TF_250

Question, If this engine had a carb and ran on petrol ie 98 then was converted to meth how much % more fuel would be needed?? 50, 60, 80, 110?? What rail pressure are you looking at running?

LOL always something Tony, this engine should run a high 8 sec pass and when it does it will be yeah but you can't beat Ken!! love it. totally different racing programs. No one will beat Ken, NO ONE!! period..... not even a hammer-wielding god engine from FNQld!!!

Im running 38mm ITB's ATM might look into some 48-50mm and see what happens.

For now!!!

LOL Hollywood, those afr's look spot on. 5000 13 .885la 5500 13.25 .90la 6000 13 .885la 6500 12.5 .85la 7000 13.5 .92la I run mine in the same range, even up to .94 every time I roll into the water box and I'm on petrol I'd run more on alcohol. My Crossflow wouldn't go that high but then again you need 10 degrees more timing in a Crossflow then a Barra .88 under load is to rich for these engines mph loss is a result. Barra to the front. Crossflow to the dump!!!!

505hp @ 6600 Barra to the front!!!

I've got 2 bellhousings here!!

I guess it would depend on what main fuel tank you are going to use, if the std cortina tank is staying then use the surge tank for sure. If a fuel cell is to be used the way look at it, like my setup is it is basically a 20ltr surge tank. 2 044's will be plenty. Also us you would now the more electrical load you have on the alternator the more hp it will take to drive it, an extra pump in the boot may not seem like much but every Little bit helps, 1 044 will pull upto 15amps!!. I had an alternator drama and had to use a poor quality back up and went from 13.7v average to just over 12.2v and cost a 0.05sec and 1.5mph!!!

Thats the one

thanks mate they look better now they are all powder coated black!!

O44's don't suck they need to be gravity feed, I did learn that the hard way. I run mine off the bottom of a 20ltr cell in the boot. Only ever run 10ltrs have ha 0 dramas.

Been a while since i have put an update up here, I finished off the last season well then sort of missed the mark in the finial shootout, still learning the car. I have now just been fine tuning the little things and trying different things as well. We did a couple of test n tunes in dec & jan trying a new gearbox pickup setup and changed the cam sensors from magnetic pickup to hall effect of coarse i had to make some mounts for them and they are different intake to exhaust side. I also deiced to get rid of the original door trims and make up some alloy sheet versions to replace them because race car and all. That was all done before the start of the new season. I ran a 1/8th mile radial race recently and had wanted to try E85 again in this engine. So to do that I changed out the injectors then its all in the keyboard tell the ecu what injectors you have, what the molar mass of the fuel is and a couple of other fuel settings and the ecu will re-tune the petrol map to suit E85. The car performed about the same which was expected but man E85 burns nice, all the tops of the pistons were cleaned and all the plugs were nice and clean. I deiced to leave it for now though and head back to 98 and run my regular season on it though. We have been fine tuning the cam timing particularly the exhaust cam. When changing the sensors to hall we now have a better signal and have found some gains there. I can't wait for some cooler weather as so far it's about a 10th of a second faster then this time last year!! Also willowbank have changed the et cutoff for the series I run from 11.50 to 10.50 so no dramas trying to slow the car down in winter. check out the facebook page as well https://www.facebook.com/Jason-Stoodley-Racing-1558367151083789/?notif_t=page_user_activity

Surge tanks and lift pumps are just dead weight in a drag car mate shouldn't need it, just run the efi pump directly off the fuel tank. I have a 36-2 chopper wheel and magnetic sensor to suit ATI that was on my old motor if your interested.

far out 285rwhp in 2500lbs would run low 11's There is no way robs ute is 1180kg that lighter then both mine and kens cortina"s
