Turbo_Addict Posted May 15, 2009 Author Report Share Posted May 15, 2009 Many thanks for sharing, I've read a lot of theory and done some timing but I still think I have much to learn. Given the size of the nitrous shot I'm surprised you only have to pull out two additional degrees. Since you have no detonation, does that mean the turbo timing is too conservative? Scott From what I have read and been told, basic nitrous timing adjustments are to pull out 1 or 2 degrees for every 50 HP. I'm sure my boost only timing is quite conservative, but what I did was dyno both boost only and nitrous on 5 gals of 92 octane plus a can of Torco to bring it up to approx 102 octane. When I run around on boost only on the 'non track tune', I just run straight 92 octane. So a little conservative on 102 may be just about right, or at least 'safe enough' on 92.

Technology Posted May 15, 2009 Report Share Posted May 15, 2009 That's a strange way to tune ignition, it looks as if you put in the outside numbers and it just guesses for everything in the middle. Link to comment Share on other sites More sharing options...
Turbo_Addict Posted May 15, 2009 Author Report Share Posted May 15, 2009 (edited) That's a strange way to tune ignition, it looks as if you put in the outside numbers and it just guesses for everything in the middle. That is FIPS Ignition pro... you have your base timing per RPM range on the left and it pulls out by MAP readings and how much boost. It's certainly not like MS with the megasquirt and spark but it does the job and so far, I've had pretty good luck with it. Its relatively basic... but yeah, you put in the range, and it averages - kind of like the boxes in a VE table with less detail. You can pull up a 3d graph and it looks just like a 3d graph of a VE table, but the boxes are bigger and fewer.

TainterRacing Posted May 18, 2009 Report Share Posted May 18, 2009 I too had a high power 2.6 on a spec 3 clutch. it seemed good then I pulled the tranny and it was really bad off. I had 3 springs broke and the surface of the flywheel was in bad shape I would at the very least pull the tranny and look. I was running slicks a lot so you might be all right if you have not done that. Good looking Numbers by the way! Link to comment Share on other sites More sharing options...
lionbull Posted May 18, 2009 Report Share Posted May 18, 2009 its time for a track run. with 527ftlbs of torque we await a run in the quarter not the 1/8th. Link to comment Share on other sites More sharing options...
patra_is_here Posted May 27, 2009 Report Share Posted May 27, 2009 just wonderin, but if you have an adjustable cam gear, couldn't you shift your powerband up a bit and make even high HP numbers? Link to comment Share on other sites More sharing options...
Turbo_Addict Posted May 28, 2009 Author Report Share Posted May 28, 2009 just wonderin, but if you have an adjustable cam gear, couldn't you shift your powerband up a bit and make even high HP numbers? Not sure - I thought that just allowed more adjustment on the timing, and since I adjust electronically, wouldn't that just be the same thing? I have never jacked with adjustable cam gears, never researched them, so don't know what benefit it would give me. Always looking at new angles though, I'll do some reading.

quikconq Posted May 10, 2010 Report Share Posted May 10, 2010 Russ wat the heck you been up to???leave it to you to bump up a yr old threadkeep up the good work.... Link to comment Share on other sites More sharing options...
jinx Posted May 10, 2010 Report Share Posted May 10, 2010 BlueCook pulled 100 more horses outta a TBI car with just cam timing not so simple. First he had to get a properly ground camshaft..... instead of "assuming" a 'performance cam' actually performs (like most of us do). HUGE difference between the two.VERY few sweat cam details as demonstrated on that car. It certainly paid offLittle to no G54 cam testing done, that is why there is sooo much negative feedback from cam installs.... especially by those who dyno'd before/after (substantial torque loss).With these motors, its more miss than hit, because of that.

notfried Posted May 10, 2010 Report Share Posted May 10, 2010 Russ wat the heck you been up to???leave it to you to bump up a yr old threadkeep up the good work.... been messin' with Harleys and diesels lately...gettin' ready to hopefully re-do the beige quest(hopefully for the last time...lol) not so simple.

Funky Phil Posted May 11, 2010 Report Share Posted May 11, 2010 cam timing is not ignition timing...i betcha you can pull a lot more ponies outta yer set up with some cam timing...just watch out for valve overlap...BlueCook pulled 100 more horses outta a TBI car with just cam timing and the proper cam Its SOHC. you cant change valve overlap. You cant change anything. Just advance everything or retard everything. I messed around with it on the dyno. Kinda acted like a volume knob more than anything. a couple degrees makes a huge difference!! Link to comment Share on other sites More sharing options...
