Yeah I was discussing things with turbocamaro125 this evening. I kinda agree if go turbo to seriously consider 4L80.

unless you overdrive your centrifugal and bleed boost, a proprerly sized turbo setup will make more hp/tq much sooner then a centrifugal
and theres nothing like the feeling of massive amouts of tq suddenly coming when the turbo spools
btw ive had/have every power adder there is (turbo,centrifugal,pd,and nitrous)
the only way i would ever run a centrifugal aging is if i had a very large head unit and overdrive it and bleed boost

John what radiator setup are you using as it doesnt look like youve had to do any relocating or moving of the bottom support any

Ok now that we have talked u into turbo and a 4l80 what would be a turbo of choice for john? He wants big power on pump 1000whp+

Like Justin said a couple post ago I have a Griffin radiator and it is moved way forward. I have cut the radiator support a lot.

you know you could throw a 4l80E behind your current setup and be low 9s border 8s with the procharger setup.

A D-1SC took KP's 98 Tans-Am into the high 8's. My Camaro ran a 9.12 with a F-1A seriously blowing through the powerglides converter, the mph was only 146. A good combo with an F-1R should run 8.50's. Bob

I say fix your head unit, sell T-56 set-up and go 4L80E with a trans brake. You won't be disappointed!

ive yet to see anyone say they regretted going 4l80e, everyone ive seen say they shouldve done it sooner. My Vote, keep the procharger setup, sell the T56 to pay for most of the 4l80 swap and love the trans brake!!

I love my 80e. The only reason I murdered the one I had is my fault and the tree's fault for malfunctioning.

I have mine set-up for full manual with the modulator to control line pressure off motor vacuum. It is really sweet, and shifts nice and smooth at light throttle and just get's nasty as you press the loud pedal.

The people at PTE say my Billet Wheel 76 is good for 1150hp on the engine dyno so I should be good to 850-900rwhp with a built 347 to handle it. The 347 and 76mm turbo makes an awesome combo, you have full spool at 3200-3500 rpm (depending on boost controller settings) and a power band usable to 7krpm with that turbo on a .96 A/R.

If this isn't enough look to a PT88 to hold all your wants and desires with room for your motor to grow and power level exponentially.

I agree with some of the others. Stay with the blower, throw a well built 4L80 in it...maybe go FMVB and a brake with a good converter. Car will run in the 8's eaaasy. It'll be just as fun as the 6spd....maybe even more. How much more boost could you run on the setup? I figure the F1R should get you over 1K anytime your ready for it lol

Well john makes his numbers on pump gas

Add methanol Inj and run the boost just a bit higher. You'll be fine running 20psi with 18* or there abouts. That should get you over that 1K mark. Sick combo never the less lol

Truth. 8.50's should be easy with the right race weight, converter and gear and the 'R'. I am hoping for 8.60's with the 'C' at 3350# and a composite LSX intake keeping the stock hood.

I'd keep the blower!! The hard part is done, although things can get boring once all the work is done. It is hard to remember what it took to get there once you are there. Regrets for selling or changing always come into play later down the road. All depends what kind of person you are, and what kind of time and money you have. Been there, done that - more than once.

Good luck!

I am honestly with everyone else, keep the R, put a 80e in it, 3400 stall, trans brake, fmvb and run 8's with a 3400 rpm launch, it will be sick, trust me. It sounds like you want to go faster at the track, if I am wrong correct me.

Turbo's are awesome though, and as someone else earlier said, the feeling of my 600 ft. lbs of tq. kicking in at 3800rpm is just pure adrenaline and sex and drugs all put together. When people on the highway are staring at my car and I drop a gear and go, they always tell me it sounds like a rocket ship. LOL

I agree I could put a 4L80 in it with the F1R and run low 9s or high 8s. My first desire with the car is to have fun driving it on the STREET, being fast at the drag strip is second.

Like I have said there are pros and cons to both. A couple things I don't like about the blower is it sounds like a jet just idling or cruising, no stealth at all with a blower and adjusting boost is a pita. A turbo is quite until you get on it and adjusting boost is just a click on the boost controller. Yes you have more lag with a turbo and much more under hood heat.

I'm thinking about changing to a 4L80 and a 94mm or 98mm turbo. Justin thinks with an auto, spooling the turbo wouldn't be an issue.

The blower does have me discussed at the drag strip. I basically don't want to even take it to the track because probably the last 5 times or so I have had issues. I do think things are pretty well ironed out with the blower but I have yet to have a good clean pass in a while. Giving up on the 8-rib belt and switching to a cogged setup and adding bracing to keep the blower bracket from flexing has basically eliminated any belt issues I think.
