HB250

It get borggy but even if was hilux... Why would lsd a drag car? :/

Lol i do know all the above info been racing offroad and drag for a very long time now thankyou tho. Yes a borgearwarner would suit it to the ground. However, once this car runs its numbers it will be for sale lol

Off to street drags tomorrow lads, ill get some photos and start a thread. Chasing mid 11s. If i took 9' out it go low 11s lol. Cheers

Sorry tony, on phone, and was greasy hands at wkshop mate.

Oh... Adelaide car mate. Hod do i post photos?

Excuse me sly? Unsure you reference. How ever thankyou to bout you guys, definetly running better now, could deffinetly reciece some gains with programable timing. Ans discussed with Terry, however ill runnit at drags on sunday and let you guys know. Makes over 200rwhp in the heat threw big convertor and 9inch with only 24-25 degress, should easily run 11s now. Cheers

You guys are absolute legands, i appreciate all input. If you send me you mobile number i can text photos threw? It only makes 200rwhp, who cares about the number lol. Runs time due yo 100% hopkup and no weight. Im graeme btw, new to xflows

Is it worth trying to get a thick head gasket or bigger cam to bleed off comp? Or is it possible cam timing could affect it? What do you recommend?

Sly, are ea distributors the same? They look the same?

Sly i just remembered that on the dyno power starts to roll over at 5200 but increases alittle at 5600 is this due to timing and cylinder pressure?

Sly, i really appreciate your help! i rebuilt it due to being due. It ran 11.7 @ 109mph with small miss, just before i bought it and previous ive watched it go 11.4. i rebuild it due to it breathing fairly bad and not being able to rev (weak valve springs)i changed carby due to original 1 being obsolete (top bowl feed holley) however ive tried both carbs back to back, and the dp does have slight increase. Its actually in a HB Torana mate lol.

And why is the hall effect elec sufficent with the hall effect sensor wires on the msd?

Perhaps i will change dizzy, where do you suggest i get a tfi? Still wire threw msd? This exact combo ran 11.4 all day mate it won 2 tri series and a xmas tree at some stage, before i rebuilt it, however had no dizzy and i switched carby. Ive tried it on e85 also and still doesnt like more than 25deg either. With comp test, only shows 185 do cam must be bleeding off fair comp?

Good day mate, its electronic dizzy, im running ngk8s atm, i dynoed it today running on module only and 8s and it was smooth for about 5 runs but noises over early and later developed a miss again

Gday guys, i have a issue which i am unable to sort on a moddified 250 crossflow. The engine is one of dave adams originals which i rebuilt. I did rings and bearings and shaved head the slightest to ensure flat. Specs are, 250 crank/rods - balanced Hp balancer Acl race pistions - 12.5:1 Work c2 head Dual springs 120seat Solid cam 600lift Cain 2 barrel manifold 650hp holley Avgas. 6al Ss coil Remanufactured dizzy locked at 25degs (it doesnt like more) Now the issue is, i cant get it stop missing, ive tried everything, and only luck i seem to have is removing the ignition box and running the dizzy module but even after time it develops a miss, ive changed boxes, plugs, leads, carbies, dizzys and cant get rid of it, Anyone ever had this? Is it possible dizzy doesnt send enought trigger for msd? I need help guys. Cheers,
