Sitting beside Justin in the car, running the car on the dyno, driving the car on the street while watching Justin work, he is 100% correct. I know why we stopped there and we could very easily go further. It will happen, someone will make a huge number on the dyno with a similar set up to the RSI TT. This car could easily do it if the owner wanted it done. I have to agree with Justin.It is only a matter of time.houstonT said:I know when Justin Nenni tuned the RSI TT car he said to me "if I had free reign on this car, i'd make 1500 rwhp and 1500+ rwtq with these turbo's". I think it's VERY possible to make upwards of 1500 rwhp with the viper motor, i Now with the AEM out, it's easy to make a 1200+ rwhp viper run/drive like a stock car (with the right tuner of course).
Tanked said:houstonT I agree. Finnaly a the vipers get the EMS system. I've seen it do wonders on may cars...including DSM's. It's impresive to see a 2.0 4cyl make 400whp on pump gas. Tuning is 80% of how good a engine will run. I've seen that time and time again. System setup is only about 10% and 10% is how good the parts are. I remember working on a dsm and could figure out why the whole system wasn't working. Turned a bearing in the NEW turbo was DOA.
My turbos are mounted just below the flexpipe off the headers. The oil return fitting is 1" lower than the frame rails. I am now making al finned sid plates to shield and disapate heat. I would be curious to see how they get the rear mounted turbo tucked up to retain gound clearance. The innercooler also has me curious. It is a major fallicy to think you can compensate for pressure drop by turning up the boost as that will only generate more heat. It would be to thier benefit price wise and function wise to drop the innercooler and use the tubing to cool the charge (maybe with heat fins- or some other creative way) By eliminating the innercooler you also keep the airflow to your condensor and raditor. They could make this a really cost efficent package if they approach it this way. $1300 for a 80 trim turbo, $600 for the oil pump and lines, $1500 piping fab, $500 gages and misc. With out a fuel system upgrade you can safetly add 150 more RWHp. So for less than $3500 your at 550 RWHp, cheaper than a Roe system. (minus tuning and piggy back)Tanked said:1.) Because the engine in the viper is so large. I don't spool time will be much of a issue...even with the turbo in the ass of the car. I think the "lag" that would be felt with such a system would be due to the long distance if the IC was in front of the car. What about putting some type of IC in the rear of the car too. I have no idea where it would go.
2.) Ground Clearance. If a stock viper is lowered 1" would the turbo system be rubing on the ground?
3.) BOV where would you put it? In this "odd" system wouldn't you want to put it as close to the turbo as you can? Because that way you don't loose all the pressure between the BOV to FMIC(assume) to TB's??? Or would this cause a (air bubble...or lack of air as it maybe) in the turbo system and cause a temp super rich situation??
4.) Because the air has so far to go and air would be moving arould the pipe going to the FMIC, what about using a "finned" pipe going to the intake and using the pipe it's self as a "intercooler". This would help cool the air before it even gets to the intercooler. IF it worked good enough...you wouldn't even want a intercooler....just a radom thought.
Ok that was just somethoughts I had. What do you all think.
