Ok fellas, here goes.
My engine currently has a TE60 turbo, 36 lb Ford blue top injectors, a Turbo Tweak alky chip burned for 92 octane and a D5 converter, no idea if it's restalled or stock. I'm also running a Razor's alky kit. The camshaft is a Postons grind (GN110T) with a 212/206 duration @ .050.
Recently I installed a Powerlogger which revealed that at WOT my injector duty cycle is at least 90% and sometimes even as high as 105%.
I do sometimes get some knock, most of which I believe is false, but a few times were at WOT and the AFR was in the 11's and not the usual 10's. Fuel pressure is rising 1 psi per boost.
Some have pointed out in the past, that "you must have those blue tops maxed". One individual has told me "you're fine with those blue tops as long as you're running alky", which I obviously am.
I believe I've read in other people's posts on injectors, posts, something along the lines of "if you run anything over 80% duty cycle, you're asking for trouble". However I've also read in other people's posts, that blue tops are safe into the mid to high 11's. I believe GNTType.org even points out that you can run into the 11.70's on these injectors.
My car has only gone a best of 12.61@109 on a lousy 60 ft, and that's not a traction issue 60 ft either. Shawn (youlikethat) verified at my initial passes down KCIR that there's a bog off the line. You can't floor the pedal in this car on a dead stop and spin the tires until the car moves about 10 feet and a second later. Then the turbo spools up and shrieks the rear tires before scratching 2nd.
My car weighs with me in it, minus the spare tire, and a full tank of fuel, 3705 lbs.
On the 12.61 pass my launch was on 7-8 psi as at the time I didn't have a line lock for roasting the 275/50's (yeah I know I need a 275/60 tire) so the shoes were a little warm...anything more than 8 and I would have probably went thru the beams trying to brake launch.
I have heard from one former GN owner that "get a converter and 1.60 60 fts. are yours".
Therefore I'm thinking my car needs both a converter (perhaps that might help the 60 ft...?) and......possibly injectors?
Now...I understand the 60 lb injectors are pretty much a 1 time investment. And I'm sure they'd be the best for my situation. But trying to buy both a new converter AND a new set of injectors/chip.....getting a little expensive for a single income guy supporting a household.
I can't remember but I believe I read that a TE60 turbo is good for low 11's? I don't plan to replace it but I do want to optimize what I have power wise. In other words I want to milk what I have for all it's worth. So we'll just say my goal as of now is a low 11 second 1/4 mile time on 92 pump gas and alky.
So now my question....
(1) Even though certainly not the best injector out there, but most certainly less expensive than the better injectors, would a set of 42.5's from Turbo Tweak be ok to use with the turbo I have and the 1/4 mile times I am aiming for? Would/could a 42.5 injector support an 11 second 1/4 mile time?
(2) As for the converter, I've been told I need a 2800 stall. Should I go with a lock up or non lock up? I still have my BRF 200-4R. I do interstate driving. And should i go with a custom built converter? or is there an off the shelf brand that you know would work with my combo?
(3) Would having a presumably stock D5 with the TE60 and the GN110T be a leading in factor of why I have a poor 2.00 60 ft time that's been confirmed as not a spinning at the light issue?
I apologize about the long post, but I need a little clarity.
Thanks in advance.
