OK I have 3 options with my truck.

1. Get my STS tuned and add meth. Which should add 50-75 RWHP. Problem is the number of STS engines that have blown pistons.

2. Take off the STS and sell it on EBay at a loss. Then buy the new Roe Twin Screw S/C and have roe put it on and tune it.

3. Take off the STS and replace with headers and meth. Then just run N/A.

1 is the cheapest route other then the risk of blowing an engine.
2 cost more and I think is a better design.
3 engine lives longer but less HP.

What do you think?

I'd go with a ROE top mount if I could talk the spousal unit into not kicking me out of the house for it :jest:

There is something about a built N/A setup too. I think I may be able to swing a cam swap and a little head work some day.

The most important thing is to get a good tune. I think if I were you I would get on the phone with ROE (if you haven't already) and get his opinion of running the STS with his tune.

Good luck either way. :drive:

I agree with VT2933 since you already have the STS get Roe or DC a call for their tune. Good luck with your decision.

My truck is going to Roe in June. So they would be doing the tune and meth on whatever I have or get. If I go N/A, then I would not do anything at this poing other then add meth.

I would let Roe tune it and if it still gives you problems (and after you wipe the drool off your chin :devil: ) you should probably install his top mounted S/C ;)

Of course thats easy for me to say since its not my dime :)

I'm not having problems other then low power, which a good tune and meth should fix. The problem I'm worried about is the piston. I just don't know exactly how many pistons were lost with people only running 5 psi.

A good tune with 5 psi should not be a problem.

Well there is the old traction problem :eyes:


Sean may be able to make some improvements on the oiling/flow etc...to help reduce the #3 issue. I can understand your concern, I would be worried too.

I have been in contact with Roe. Not much help for improving the system. They are S/C guys, not Turbo guys. They have no R&D to help them make the system better, plus it's not their system.

I'm thinking about caltracts.

Well, you could always sell it and get a Lightning, or an SS. :jest:

Wanna trade?

Haha, you'd be going from one issue to another. I've got a lean condition that may or may not be sorted out yet. Waiting to see if I melt any more plugs, lol.

True, but I believe they put their hat in the turbo market as well. Add in ten years experience modding Viper enginees...not that there is a silver bullet but they may have some generic mods to reduce the risk of a meltdown.

I am thinking about Caltracs as well but plan to install a 1"x2" X-Metal drop kit first. It looks like Caltracs come in two different versions. Std and for lowered trucks. I think the Caltracs for the lowered trucks are shorter.

This is my post from SRT10 forum:

My tune is from Roe and I'm on the rich side. And I have also seen high boost, 10+ :eek: . I want to believe in the system and I somewhat do. Here is my opinion.

1. Big asp-first engine due to open loop. Result-fixed for all STS systems.
Second engine. Ran it without the turbo hooked up.
2. SCvette- Running propane/meth over 8 psi on stock engine. (I think)
3. Sprite- Lost his on the dyno. If his was connected like the instructions then he over-boosted. Result-New reference kit for the boost and lighter springs.
4. RamfromHell-Don't know what happened here. Eric let me know the details if you can.
5. Cardude/Jet and myself sill have ours. And I know of one non-forum member who has one. I wonder what the difference is? Tune? Boost? My install guys caught the overboost problem early and hooked it up the best way they could figure out. I sent this info to STS and now all kits are hooked up like that. At least the QC's are.

The point of the above post is that other then Eric's the rest were caused by different problems (to an extent, end result the same).

A good tune with 5 psi should not be a problem.
:werd:

What kind of RPM do your guys' motors see on average? Also, what's the stroke like?
