For those of you who have a supercharger if you had to do it all over again would you:

A. Stay NA and keep your warranty
B. Go Twin Turbo
C. Supercharge Again
D. I blew up my F#$%@&* Engine!!!!

 

I blew a piston , but I would go TT if I had to do it over .I like the Vortech , But I am envious of the torque of the TT

 

Thank You King Tut!

booger how much did that blown vavle end up costing you to fix?

 

bump

 

TT, because adding a boost controller is the closest thing to having something like displacment on demand and that is what im looking for in a streetable race car.

 

Just starting to get into it .Rods, pistons ,cams , heavy duty springs , Injectors ,. And while Im at it ...6MT VLSD swap , May be a SS box upgrade , or some type of data logger...$6,000 to $8,000 total . Im not going to think about it till its done and I have to start paying for it

 

Can you turn the boost all the way off with a TT setup?
What do you guys think of the new single Turbo that came out yesterday?
Do you think it will be reliable?

I know it does not whistle liek a procharger but what does a TT sound like in person?

Thanks In Advance,

Tom

 

I really like the cheapness (relatively speaking anyways ) of the centrifugal kits. But I'd go TT for the useable power. I dont mention a roots type SC because of it's limitation on boost, less if a whipple derived kit where to come out... *hint *hint

 

Here are my .02's...

If you are interested in the TT, build the motor first. Count on $7-$10K depending on how impressive you want to make it. Then get the TT kit and have it installed for another $10K-$15K including gauges, tuning, fuel and tranny upgrades. This will be the ultimate setup and will perform accordingly. However after spending $25K on a $26K-$37K car it seems a little ridiculous and you haven't even upgraded the wheels, tires, suspension or brakes

With the supercharger you will not be able to boost as high or create the amount of torque as the TT. It will also produce less HP per psi as the turbo. However for those not intending to build the motor this can be a good thing. Many people beleive the torque is what is bending/throwing the rods. Since the SC lacks the torque (under 10psi) they don't have this issue. This is not to say the SC is perfectly safe. The pistons/rings are the major issue with SC's. From what I can tell the problem is tuning. (a combination of timing and AF) If this is not perfect then you will find yourself with a blown motor. The AF should be between 10-11 during WOT. A complete set up here can run around $10K-$15K including the install, tuning, fuel, gauges, tranny and some extra parts like cams, headers, HF cats, plenum, ect. (You can tack this stuff to TT costs as well, minus the headers)

N/A mods are nice but I grew bored of them quickly. I bought this car intending to add FI. If that wasn't the plan from day one I would have never bought it.

In short, if you have the money go all the way. I am into this car $50K and will never get that much out of it. I have an SC and I'm quite happy. I feel very safe boosting 7PSI and hitting nearly 380rwhp. I don't foresee any issues at this boost since I have literaly spent months having this car tuned properly. If my motor blew like yours, I would not build it only becuase I feel the supercharger will not take advantage of the increased strength and cost of the motor. I would fix the piston and spend all my time and efforts making sur the car was tuned perfectly.

 

I take it the last portion was directed at me . I plan on using the 2.87 pulley and make 11 to 12 lb's of boost . Im not trying to be impressive on what I got in the motor . I plan on keeping this car for years and want it to last and be reliable . When its payed for I may go TT . As far as tuning.....your right...I took it to far and I am resposible for it and paying for it . I took some advice from some one and I shouldnt have . Lesson learned

 

Hey Booger what kind of #'s were you getting before it happened and where should i stay to be on the safe side without building up the motor? I know you've done your homework so I have faith in you. I feel like I get on it alot...is this bad?

 

shoulda went TT

 

Booger, this was not directed at you. Enthuziast posed the question and wanted to know what he should do after blowing his motor. (different thread that TUT helped him with) I'm sorry if it came off that way.

There are many others like you with the vortech kit or ATI kit that have had issues. Even guys are having issues with stillen and HKS. Hopefully I made my point clear that even a SC is not safe if not tuned perfectly. However, if compared to a turbo, you are much safer IMO. Mainly because you can be tuned perfectly and still bend/throw a rod. Another issue that I forgot to mention above are boost spikes. I know of at three blown motors claiming boost spikes which does not occur with a SC.

 

Was this directed at me? If so, please let me know what you think it was. I know we talked a lot before your car blew up. You believed me that you don't have to pull any timing. j/k

 

It was John at Grubb's . Plus seeing the maps from the cars he tunes .

 

Barzten...I was making 351whp on a Mustang Dyno loaded for a 3,700lb car . It wasnt the hp ,it was me..I only had 4.8 degree's of timing taken out at 9lb's of boost . It shouldnt be less than 7 degree's . Unless you able to tune it perfectly and have high octane gas in it .
