Car Forum / Ford / Ford Mustang / October 2006Supercharging a 96 cobra
Ok I'm ready to supercharge my cobra but I know I have got to be very careful about the parts I use? I want to go intercooled 7psi but no more because I've heard horror stories of blowing up the bottom end. Has anyone supercharged their 96-98 cobra? what were your results? what did you run? How long did has it been running? > Ok I'm ready to supercharge my cobra but I know I have got to be very > careful about the parts I use? > I want to go intercooled 7psi but no more because I've heard horror stories > of blowing up the bottom end. > Has anyone supercharged their 96-98 cobra? what were your results? what did > you run? How long did has it been running? What type/brand of blower do you plan to use? kenne belle ts1000-96c $3700 with cooler extra pulley for 7psi and pulley wrench should get about 330rwhp without too much hassle(at least Im hoping) my goal is to run 12.90's all day long > > Ok I'm ready to supercharge my cobra but I know I have got to be very > > careful about the parts I use?

With the intercooler at 7 psi, and KB's tune, you should be just fine. You are going to love the twin screw. It will make you think there is a nice high revving big block under the hood and 12.90s should be no problem. You might want to do a clutch upgrade and rebuild the Traction-Loc differential to handle the low end torque. ;) > kenne belle ts1000-96c $3700 with cooler extra pulley for 7psi and pulley > wrench [quoted text clipped - 10 lines] >>> you run? How long did has it been running? >> What type/brand of blower do you plan to use? note that you can get more boost than 7 with smaller pulley. Intercooling is the way to go. I have an 8 # KB with a 5 # pulley, but it will put out 8 pounds at 4,000 rpm, so I have to keep rpm low, and use octane booster in gas. Course I could put retard on, which I should, but have not. (no intercooling either) Stay away from detonation KB has the best low end torque of any of them, well worth it, too much fun 87 5.0 93 5.0 8# > The KB kits are very well thought out and are one of the safest ones you > can install, IMO.

I have a Blowzilla/Flowzilla combo on my '89 LX with water/alcohol injection to cool the intake charge. I have run up to 16 psi but the heads on a stock 302 block tend to lift at that pressure. Any little bit of detonation results in a blown head gasket. That being said, 16 psi from a twin screw puts a new definition on what one defines as good throttle response. The low end torque at boost level tore up the stock T-5 in short order. Accelerating hard in third gear just after rebuilding the traction-loc, with the extra clutch in each side, did it in. You should look into water injection. It works wonders for cooling the intake charge. In some respects I believe it works better than an air-air or air-water intercooler. In addition to the cooler temperatures the presence of water vapor helps to suppress detonation and keeps the combustion chamber free of carbon buildup. > note that you can get more boost than 7 with smaller pulley.

Seems like it would have to tie into the tack or mass air somehow, so a home brew would not work too well. I ran into a chart that had the tradeoff between HP and water vapor somewhere, did not seem that bad, the tradeoff is worse backing the timing out. >I have a Blowzilla/Flowzilla combo on my '89 LX with water/alcohol >injection to cool the intake charge.

I use a modified version of this kit: http://www.smcenterprises.com/ It has a very good controller and is adjustable from inside the car and on-the-fly. The trigger is boost and/or rpm sensitive and adjustable. The flow rate is adjustable using pump speed and nozzle size. It takes very little water to cool the charge and I can run for several tanks of gas before hitting the half full mark on the quart sized reservoir. The key is to only use enough water to cool the intake air. When properly dialed in it won't cost any horsepower and will allow you to run a very aggressive tune. I also use a J&S Safeguard knock sensing, timing retard. It pulls timing when detonation is detected from a block mounted sensor. Here's a link: http://www.jandssafeguard.com/ A guy that used to post here, Ed Clark, did extensive tests with water injection. He actually mounted a temperature sensor to measure intake air temps before and after the water injection point. On a hot and humid day at a track in Virginia he actually recorded intake temperatures BELOW the ambient air temperature. Also, that day, he won his class in his '99 GT with a Novi 1000 against some stiff competition that, on paper, should have beat him. IMO, the water injection likely gave him the edge that very hot day. An intercooler can never get below ambient temperature at best. Water injection can and is very consistent once it is dialed in properly. > who makes the water injection stuff ? > [quoted text clipped - 55 lines] >>>>>>> you run?

Thanks!, hot on the trail now, make that 1993 8# chill out some and go faster! >I use a modified version of this kit: http://www.smcenterprises.com/ It >has a very good controller and is adjustable from inside the car and [quoted text clipped - 82 lines] >>>>>>>> you run?

I'll be happy to let you know my experiences and they may save you a little agony. BTW, with water injection you should be able to run 10-11 psi with a good tune. Running 8 psi will be easy, and very safe. > Thanks!, hot on the trail now, make that 1993 8# chill out some and go > faster! [quoted text clipped - 85 lines] >>>>>>>>> you run?
