Going for 300bhp!

[AdirondackFox08]

Yeah the intercooler (actually the correct term is aftercooler I guess, since the intercooler is the correct term when it's between the two turbos, cooling the air from one turbo to the other) should be between the turbo and the throttle body. Like you said, the stock svos had the small intercooler in between the turbo and the tb.

 

[Johnarmymp552]

Yeah, I was going to point that out to ya. Lol.

You need to route the output from the turbo to one side of intercooler (input, called hot side) and then the other side of intercooler will go to the throttle body (coldside).

You need to use hard pipes, typically aluminum, silicon couplers and good hose clamps-

Regular hose clamps should work for up to 10-12 psi, after that go with T-bolt clamps.

300 bhp update. I've been experimenting with how to reroute the "Aftercooler". So far i just haven't had the time to disassemble the front end again. I have decided to see if i can go down to a 2 in, diameter tube to allow the turbo to more quickly pressurize the system. I'm trying to avoid the over priced turbo kits that are out there . You can't tell me a length of aluminum tubing cost over $200.

Well followers sorry I dropped off the radar in the last month but with the up coming All mustang show approaching I wanted to get the engine compartment cleaned and painted a little. I also added a new girdle strip to the rubber bumper around the car and I added a Red,White,Black pin strip around the nose and grille that matches the fender stripes on the driver's side fender. It looks fantastic and this is how the car will be finished when repainted next year along with a GT Turbo emblem on the hood. So I've been a busy boy. I also removed the Valve cover, Stripped it and repainted the whole thing. While doing that I also cleaned the throttle body and air in take before reassembly.

Now back to the 300 hp. quest. I'm happy to report that after living with the inter(after)cooler in its present configuration It HAS significantly INCREASED the horsepower out put of the little Turbo. The jump in power from 3000 to 5000 RPM's is definite and noticable. So, why is it that this is working so well? First off the Unit is a 24in.X12in.X3in. unit that would normally go into a V8 car.The piping into the air meter box is 3in. in diameter. So a whole lot of cool air is pumping into the turbo. The distant from the Turbo to the throttle body is about 12in. or less.

If I was to reroute the turbo to the intercooler then back to the Throttle body that air would be traveling through several feet of pipe in the engine bay area reheating as it leaves the intercooler and heads back to the throttle body. I've looked at several Intercooler installation and so far mine, as configured, has less footage to travel through and also less pipe to have to pressurize. And what a difference! She's still more a road car than a dragster but She's definitely faster!

Quick update. Hit the track at the Glen yesterday. The L'il Turbo and I were right behind the pace car. We listened to instructions and followed his lead all the way around the track. He rarely had more that a car length and a half on me. What is noteworthy was the self acclaimed Drag racer In a Rousch Stage 3 at times 4 or 5 car lengths behind me through the dog leg. Of course in his defense he was turning! LOL!!!

 

[djhayes1963]

I was 2 cars back in my 12 modded 6er, the gt in front of me was slowing me down, lol. You were running strong in the turbo, surprised me. We dont need 400+ hp to get around the track

 

[GTNT83]

Thanks a lot! She really is a runner. I don't pretend she's anything she's not. But she has great excelleration and incredible grip. Her tires were squelling through some of the curves but she but she never broke loose and hung tight to the pace car. Looked back at one point in the dog leg to see the guy in the Rousch Stage 3, 4-5 car lengths behind me. Man is that satisfying. Ford built a great little engine in that 2.3

 

[djhayes1963]

That's a 2010 4.6 stage 3, little over 400hp, not a coyote, my 1 in drop and lca, uca, and panhard bar helped me, as well as the Pirelli s. Gotta upgrade my brakes to gt calipers, rotors, and hawk pads for next year.

 

[GTNT83]

No need to up grade the brakes do what the Pace car guy did. he got up to speed then kept it in 3rd gear all the way. he only had to hit the brakes a little.

 

[djhayes1963]

the guy in the new gt vert was slowing me down, had to keep from ass ending him, the coyotes are torque monsters and get squirrely accelerating out of curves unless you change out the lca's and put in lowering springs.

 

[GTNT83]

Yeah I had that problem last year, kept crawlin up the other guys a** in front of me.
This year I followed the pace car drivers instruction and kept it in Third most of the time only using second to climb that back hill in the dog leg and fourth on the straights. Of course given the chance I'm sure all you guys would or could have made a pass on the straights but my l'il Turbo LIVES in the curves! I'm mighty proud of that little car!

Saw some pictures with your car back there very nice.

 

[GTNT83]

Well the next two things for the car . A new back seat to match the front seats redone by JMB of Canandiagua. And a new free flow muffler. Either by Pypes or a Cherry Bomb flow through. any suggestions?

 

[GTNT83]

Okay my question.... What do the members here think would be a good option for a muffler for my turbo engine? One suggestion has been a straight through Cherry bomb and another was a straight Pypes muffler. but do these afford the proper back pressure?

 

[AdirondackFox08]

You can get any straight through muffler you want for your turbo. The turbo makes enough back pressure so you don't need to worry if the straight through design will lose you power. Borla, Magnaflow, SLP, and some other companies make the straight through mufflers.

 

[GTNT83]

Well yesterday I broke down and bought a MagnaFlow straight through stainless steel welded muffler. Not much to it but a bend in the pipe and some packing inside. i can't wait to get it installed . The pipe from the Cat is already a 2 in. stainless steel piece and the tail pipe is a ceramic painted split. The shop might have to put a bend to connect to the tail section. This will give me more air our to go with the Intercooler I installed this summer. I hope to increase the boost from the stock setting up to 12psi or more we'll see, that and a fuel pressure gauge are on the shopping list. Now if I could only find a dyno around here where I could get my horsepower tested. Any suggestions???

 

[GTNT83]

exhaust update:I took the new Magna flow straight through muffler up to a local shop. Unfortunately the muffler didn't have an offset on one end and wouldn't hook up easily to the tailpipe. At first I thought it would mean returning the muffler and ordering the right one . Then I had a thought, the Magna Flow a straight throw design why not just have the shop bend me a pipe to connect the two pieces I had. Its what other SVO owners had recommended. Soooo, Thats what I did! The turbo creates its own back pressure and I am running a pipe straight from the cat back. What a difference when the turbo spools up the engine runs stronger and climbs faster to 100 the acceleration is impressive mostly because of how strong it is going up. Even as its approach the ton its still climbing with a feeling of power to spare. Quite impressive. I so wish I could get this thing on a dyno right now just to see where I am in this 300 power quest. I still have a fuel pressure regulator to install and higher pressure injectors but I'm most excited to look into a new alcohol injection system I saw on a turbocharger firebird last week. Its cheaper than nitrous and a direct injection system into the air stream. The firebirds owner says its a natural pairing for turbo engines. I'll tell you more after I look into it, and the cost. The rear seat is almost done and will be replaced soon. I hope to schedule the body shop this winter to get the body done and the engine rebuilt before I install the alcohol injection system.

 

[GTNT83]

Merry Christmas everyone! Well The little stang has been put a way after the exhaust system was finished but before I put here to bed I got the rear seat back and reinstalled along with the new dash pad the interior is almost complete. The engine idle seems to need adjustment up a little but I'll wait until I get it out a few more times before seeing what it needs.

Still planning on going to the higher pressure injectors and the regulator and then see how it goes from there. Happy new year.

 

[GTNT83]

Happy Easter, Happy Spring to all! Well after a long winters nap I have decided that its time for the body work to be done on the 83. At least 10 years ago the GTNT was being stored in a barn on my old farm property when a heavy wet spring snow brought down the barn. Luck was on my side because the car was parked toward the front and the front wall held. but as the rafters came down several hit the car on the roof, the front fender and the rear quarter.

I have also had a dilligent battle with rust on the doors, the hood and the hatch. liberal use of rust inhibitor stopped most of it from spreading but there are a few spots that need replacement or repair. While this is being done. I'll be adding Frame rail connectors to strengthen the body and support the weakened area in the floor pan.

Last week I pulled the car out of the garage to stretch its legs. My concern was with the new exhaust system I had installed. To refresh memories I replaced the cat, then went with a 2 1/2 in pipe straight back. The cat is giving me all the back pressure I need with the turbo. After a few runs the car idles even lower now. The sound from the car when you rev it is wonderful with a nice growl and a burble at idle. But what amazes me more is how quiet it is at low idle. With the inter-cooler installed last summer and the exhaust it is amazing how fast the engine climbs to red line. Considering that this is 30 year old technology I'm quite impressed with out this simply improvements have gained me so much power. Though I have not dynoed the car yet seat of the pants feels like 200bhp or more. Next will be bigger injectors, a fuel pressure regulator, solid steel fuel lines and finally and alcohol/methanol injector. Saw one the end of last summer and i believe that will get me to the 300 bhp mark.

Well summer is here and the restoration has begun at Shahin95 Enterprises here in upstate New York. After they did a proper cataloging of what the car needs they started the disassemby and then the striping down to bare metal. new doors were a must along with the rear hatch, What was amazing was how little rust there was on this 30 year old car. I guess I've been doing everything right the last 20 years I've owned this car. So here are some pix of my baby going under the knife uh, a mean sander.
