Procharged, turbo? Advice?

[2002BOSS]

Been out of the game for a long time, a little back storey. My car is a vert, full suspension, mini tubbed, narrowed 8.8 with 9" ends, was manual brakes and steering.

I pulled it apart to put a proper cage, new high comp engine 88 turbo, TH 400 but then didn't have the heart to cut up the car more and its now sat for 8 years while I played with my corvette.

Recently broke my leg and have sometime, Would like to put it back together into street trim with power steering and brakes, maybe upgrade the cage from a Molly 6 point to 10 and stick my aluminator back in with the T-56 for now.

I had done a ported Shelby blower with a cog drive to see how fast I could go with the Eaton. It made one pass 6.80 1/8 and 10.66 in the quarter. Turned it up and went 6.70 but kept braking blower parts before the 1/8 on the 1-2 or 3-4 shift. either the shaft or the cog belt would shred.

Long and short I don't want to use the blower anymore.

Been looking at F1A and F1C Prochargers. I want to stick the car back together but I really don't have the time to open up the motor and up grade the pistons ect. Also think i want to stick the hydro boost back in and my power rack. I have skinny's and slicks but I could do one hell of a 19/20 combo with the mini tub and narrowed 8.8 for the street/cruise

Was looking at pro-chargers, either F1A or F1C but after looking I don't see any fast pro charged stick cars?

Maybe I'm not looking in the right place? Not looking for a highway pull I'm taking 1/4 and drag racing.

Maybe I would be best to go turbo? Maybe do smaller turbos now and upgrade over the winter when I can open up the motor and put some higher compression pistons in.

I have tried to catch my self up for days but it's been alot of reading lol

I have found a set of Nelson racing 60's brand new, also some GT35R's

Car was 2950. I'm guessing after the hydro boost ect it's going to be at least 3050 or 3100lbs. I know I'll need to do a gear change but I would like to get it back out and break into the 9's

A stick car, I would do a gen 5 whipple. I wouldn't even waste my time doing a procharger or a turbo setup with a T56. It's just not efficient. I don't care what the stick guys say.

I'm sure you will be piecing the procharger kit. Not off the shelf from procharger bc that kit is not good at all. Just do a search on juiced46. He was one of the first 03 cobra guys to have a procharged cobra back in 2004. If I recall, to make the kit work, you need to change over to a air to air intercooler, upper intake and lower intake. The lower intake on the cobra's were designed for a positive displacement blower. The kit has to be massaged in order for the car to run how it should. This way you are not leaving anything on the table. He did a lot of research and knows exactly what to change on the car to make it work.

Yep. You can make 800hp with a Gen5 Whipple and E85.

Why struggle with all the other stuff.

And same on the turbo thoughts. I had a turbo stick car and would def go auto if I did it again

I appreciate the advice but when I freshin up the motor with my high comp boost pistons I'd like to turn it up to silly power. I have friends with supras.

I think the car would be awesome with a whipple and e85 but I can't get e 85, I had it on my last set up and the e85 would go bad before i used it.


I didn't know the A/W intercoolers didn't work. I had saw lots of people use them on the porchargers and turbo set ups and thought it was a good idea

 

[stangfreak]

If you want to make silly power, then you need turbo's. You don't have to worry about belts and can change boost on the fly. You can make 1000 plus with a gen 5 whipple on E85. But if I were to make a street brawler, id go turbo, auto, built motor. some have put a built a 5.4 4v and turbo. That setup right there is nasty. Like I said, look up juiced46. He wrote all about the centr swap and what to do for these cars.

I never mentioned it on the forums but I was going to get a 99-04 mustang gt and do a 5.4 4v swap, big single turbo, TH400 setup.

Iv driven and been in every setup you can think of in these cars. From apten ported eaton cobras, twinscrew with nitrous, to auto/twin turbo, you name it. Fastest car was the auto/twin turbo setup. My good friends comp orange cobra. That car on low boost, 12lbs, was stupid fast. 12-17lbs on the street he got most cars covered.

 

[2002BOSS]

I see what your taking about and I completely forgot the lower has literally no runner length.

That's likly going to be an issue just as much with the turbo set up as it would be with Centri.

I tried to find some info on his centi set up but found it hard to keep up.

Do you know if he dragged the Procharger with the T-56? If I did the set up I would make my own blower mount, run it with Cogs and a sprag. Wonder how long the runners are
On the N/A cobras

Turbo and automatic will always win.

 

[Blackedout]

I’ve run an F1-A cogg with an auto ... with the stock A-W intercooler we could only push 25-26 psi and wound up popping the procharger intake... Went to a J2 turbo lid and J2 A-W intercooler and still the same issue... put down 878/708

If you go the Procharger route definitely do a A-A intercooler...

 

[2002BOSS]

Do you have any dyno graphs from it?

 

[Blackedout]

Here’s one... never made it to the track as it didn’t like the maf location up by the tb... when it was at 750 hp it ran 10.2 @ 144 with a 1.80 60’.... needed more gear down low for sure.. iat’s never went above 100* and that was on a 88* and humid day...

I believe @JetmechF16 and @2fst4urtrk would be the two best to answer this question as they have both combos.

I ran an F1A with a big bore set up and it was a blast. But that was in an 01 Cobra.

 

[Roots-type]

A friend/coworker used to have a 97 Cobra with a SHM 5.0 stroker, F1R pro charger and made 1276whp. Depending on how bad ass you need to be, that was, at one time at least, an option. I would never go anywhere over 650whp without e85/race gas/torco though. (Jmo)

I don't remember if he dragged it. Its been so long ago. I just know, the two very first cobra's who went procharger and kept everything stock and installed the off the shelf kit removed that kit right away.

The T56, its just hard to control the car with that amount of power. Its doable but, its not easy. My good friend has a notchback with a cobra motor swap, twin turbo setup and a T56. The guy can shift and is an amazing driver. its a tough class he told me. I just think the car will go way faster with the auto. Hands down.

you can see my friends reaction in the TT cobra. This was on 12lbs of boost. Nothing more. 4R70W. I was in this car 5 minutes before this was filmed. same day. This is what I was talking about. =) TWIN TURBO AUTO. you will always win.

Exactly. you ran it on a 2001 cobra. Not a 03 04. TURBO > procharger. No brainer. The off the shelf kit is not ideal. This has been talked about for years. A properly setup centri car will blow away a twinscrew car. Now that we have a gen 5 3.0, its a bit different. But a centri car will make way more power and be stupid fast.

Don't quote me but if I remember correctly, when the procharged terminators were making 690rwhp, they were racing ported eaton cobras making 100rwhp less and they never pulled on the eaton. yea, it made cool peak hp on the dyno. Again, that was the bolt on kit from procharger. Revamp the kit, and its a different animal. But, to me, turbo/auto. No belts, boost on the fly, spools quicker.

 

[stangfreak]

badcobra just told you as well to go turbo. He has a 1600rwhp 03 cobra. This is just advice. Its your car and do what you like.

 

[BlckBox04]

I'm in the same boat as you, I got to a point racing my 04 that I needed to really start hacking it up and don't have the heart to do so, so I started just focusing on my vette too.
I vote turbo

 

[robvas]

Can't you just stick a Mach 1 intake on it?


Here's Bama's 700+ whp Procharged cobra that could only go 130 (they went like 121 or so with the Eaton making < 500). But they had tall rear gears in it. I'm sure it's much better with the C heads but I know my car feels gutless below 4500 (could use 4.30's but then I'd have to shift into 5th)

 

[03 Cobra DSG]

Turbo and 6r80 in my 03 cobra, I would never go back to a Whipple. Long tubes are a pain in the ass, and just seems like everyone keeps switching to the newest gen Whipple to not make much more power than they did before.

I love my 5.3/F-1A-94/T56/IRS combo but it is 100% a loud, fun, extremely obnoxious street cruiser. If I were looking for a drag silly power car it would definitely be twins with an auto.

Agree with stangfreak, the 03/04 Procharger kits always seemed like a garbage combo with too many compromises to make a package fit the stock intake/intercooler setup.
However with a '96-98 timing cover, House of Boost dedicated drive 8-rib or cog (they send both brackets) setup, A/A intercooler, and most importantly nice consistent Houston E85 the car is a ton of fun on the street. 3.73s helped with the "centri lag" immensely, would be even better if I didn't have 28" tires.

1 5/8 JBA primaries are probably holding me back along with airflow restriction at the blower inlet (see pic). Gonna solve the exhaust issue soon but still working on the inlet.

Lot of words to just say, go turbo/auto haha.
