If you have any more questions, please feel free to email me so we are not hijacking Jr's thread.
Would someone please e-mail this guy so he will stop hijacking my thread? [img]/images/graemlins/smiles[/img]
Jr. you have my phone # and email, if you need any information whatsoever, you have but to ask!Please feel free to call me! Sorry about the hijacking! I was just responding to Peter within the context of this thread. I must have missed his earlier interesting responses.
Whooops, sorry Jr. about the highjack... All we wanted to know is how big the turbo's are on your car! Didn't know it was top secret, FBI, CIA, KRH, KGB type information. [img]/images/graemlins/smiles[/img]
Paolo, phone call comin...

Peter,
Not directed at you whatsoever!!!!!!!
I appreciate your interest and think the same way about the turbo sizing/combinations/data on everyone’s Viper TT systems. The only difference is that I don't see any other Viper tuners freely giving information about all the specs of their systems. I'm sorry if you feel like I'm some type of secret service agent that isn't forthright on the turbo sizing issue. Everywhere we have taken this SRT, I have spoken as openly and honestly about every aspect of the system that I have the information for.
Here's a little more info on the cooling system:
The added cooling in the air to water intercooler system is a Thermo electronic Peltier chip. The liquid leaving the heat sync in the front passes through almost freezing temperatures created by this chip. It's very similar to chips used in the cooling of large computers, but it is a much larger chip. Possibly it might work on an air to air system and is worth looking into for the added cooling/reliability/no maintenance and decreased air inlet temps under and after boost.
Peter, has anyone in the Supra community utilized anything like this?
Jr.
I was more kidding than anything in my post!!! [img]/images/graemlins/smiles[/img] As for the cooling system, I have personally NOT heard of anyone using anything like it. It does sound like a neat idea though. Keep in mind though that our cars generally do NOT run as hot as the viper, although the cooler the better (to a degree). 99.9% of the fast street supras run a simple air-air. You usually don't find an air-water unless it's on a drag car.

Peter, because the SRT is much tighter than the Gen-II's, I think that the Air-Water solution is a result of there not being a lot of options from the physical displacement perspective. You have got to do what you have got to do. SVS's air-water setup sure looks good.
Heffner uses Turbonetics T61's. West Coast uses T03/04 hybreds (little small) Not sure what Henessey uses, but they probably are around the 61-70 size trim.

Turbonetics T61's?
you sure?

Jr - that cooling setup sounds quite innovative - good on you for trying something different.
My thoughts are - and to be honest - I know nothing of your mod so may be completely wrong - but unless you've found a way to create free energy there must be quite an electrical load to carry away the excess heat that a 500 inch twin turbo will generate - certainly more than the 12V setup will be happy with I'd be thinking. But I could be wrong -
have you tried getting it hot then putting the lights on full beam while it idles? Did the engine try to stall?
It takes energy to disapate energy, if this new chip can super cool without draining the electrical system or without requiring more power to generate current than it gives from intercooling - you are onto something big!

So what are the advantageous/disadvantageous of running two smaller turbos vs two larger turbos? I've heard one persons thoughts on this and am curious what you others think about this.

Dan, I know exactly what Heffner uses for turbos and it is NOT a T61.
Since nobody is telling what turbo they are using, it would not be fair to say wich one he uses. I can tell you it is bigger than the SVS ones and bigger than Hennessey's one but smaller than the ones I am using.
hmmmm, I actually saw a Heffner TT car at Tators, and they looked like T61's to me. (but may have not been Turbonetics) Also I know what they look like as that is what I am putting in my car.
Manny- the smaller turbos will spin up and create boost quicker, but consequently will not produce boost at higher levels and may actually restrict horsepower. The compressor maps of the T04 hybred and T61s are fairly close and the hybreds should still support 500 hp each. West Coast's are smaller than Heffner's
Manny, the bigger the turbo's, generally the more lag you'll have but the more top end power you'll make. The smaller the turbo's the more low end TQ you'll make but hp will peter out on the top end. It's simply a trade off...
Small turbos - quicker spool, more low end TQ, less top end HP
Big turbos - more lag, more top end HP
There really is no rocket science to turbo sizing...
Dan, how could you tell that they were 61's by looking at them on the car? Did you actually measure the wheel? The housings don't dictate the compressor wheel size...

yes you are correct to a point. They definetly are not T72 as the housing is larger and the hybreds are physically smaller, they could be anywhere in the 60 range. I am assuming 61's.

Barry,
I talked to Johnny Eletric our wiring electronics specialist and asked him to write something brief:
The "Peltier Effect", basically, is the movement of heat to the opposite ends of the joint of two different conductors. It was discovered in 1834 but hasn't been practical until some electrically conductive materials were produced which were poor heat conductors (bismuth telluride). The idea of using a Peltier to cool a source works by putting the Peltier between the source and heat sink. The Peltier will help move the heat more efficiently from the source to the heat sink where it can be dissipated. For an example an Igloo cooler with a peltier chip plugged into a car’s cigarette lighter, would roughly be 30-45 degrees cooler than ambient air. And it won’t blow the fuse for your cigarette lighter!
Jr.:
A Drycell battery is used (Odyssey or Optima, not sure which one) to handle everything that is part of the entire system. I had a 15min conversation with John and it was quite a lot to take in. He is very precise in developing a properly managed electrical system.
I can tell you that I tried what you suggested Barry. Right now it is close to 80 degrees here and a little humid. 15 minutes ago I went and made some hard pulls up through 4th gear, came to a stop light, fans were running, I turned on the high beams, turned up the radio loud, and turned on the airconditioning as a last test. The system acted completely like stock. Didnt miss a beat, draw down or change anything in the running of the car. When I turned on the air conditioning it idled up and ran perfect! I'm going to miss this TT.
The Owner just left and is taking it home.

If nobody is telling...........How do you know?
And just to put things in the proper tense you should change "I am using" to "I am going to use"
Haha, wow, it is good to see some of this new technology coming into the car scene! I had hoped to experiment a little with TEC (Thermo-Electric Coolers) a couple years back after I had learned all about it from my DPSS laser experimenting days. But at the time, it was FAR too cost prohibitive to work with such a system.
SVS- if you dont mind me asking, who is your supplier for your TEC components? I would be interested in doing some experimentation myself, now that I know it is "cost-possible". Feel free to PM if you dont want to post openly.
