Opinions Good and Bad on STS turbo kit?

Alikazam said:
You guys realize a tuner kit is just a turbo, and pipes right? I agree that STS has a deserved bad reputation in most circles and I personally would never use their stuff, I'm just saying that so long as you don't trust them to do the fuel system and tuning, you could end up with a good set up. It would be the same as making your own kit really, just someone did the tube plumbing for you. I've seen rear mount SRT8 jeeps and even a modified STS rear kit on a challenger that work great. Putting a STS kit on a 10 out of the box may indeed be a recipe for disaster, but saying one brand = destruction cuz they stamped their name on a kit even at the tuner level would be like saying if you put a ford logo on your dodge truck the space time continuum will implode. It makes no sense :)

If you size a turbo properly, ensure adequate waste-gate path ability (tubing size to and from waste gate and properly sized waste gate itself, or double waste gates, etc.) and ensure the sizing of all the plumbing is correct, you can hold low boost adequately and not create a ton of heat in the process which will lead to detonation. I'm not an expert by any means, but my brother does this a LOT, hand crafting 1-off turbo kits for cars (as well as proven kits he builds as stated for MR2's and a few Supras), so I've picked up a few things.

That all being said, I have no idea what size plumbing STS uses and maybe even on the tuner level their kit would be flawed, I don't know. Again, I'm no fan of STS, but the overall design of a rear mount turbo is not flawed, is all I'm sayin' :)

Also, NOS = Nitrous Oxide Systems, a brand of nitrous that I happen to run on my van currently. In case some here were unaware *cough* :) I'm a fan of NX systems as well based on design, and a lot of the new Zex stuff is pretty impressive as well :) Peace out!

its a losing battle bro. the STS sytem has not proved it self, so no one should do it... (every SRT-10 have blown up)

IMO - if you have the money to try to make it work and a spare engine go for it. i think the KEY with that setup is the tuner !
 
I bet Smoke will sell you an STS system cheap...he needs the money to rebuild his engine, AGAIN!
 
Putting a turbo 10-15' away from the engine is just a poor idea. A turbo works off heat and exhaust flow, you lose so much energy by the time it travels that distance, plus you have to pump all the air back up to the front, as well as pump the oil, etc. Just a poor plan for performance if there is any other option. I know rear mounts can make good power, etc. but look at their power curve compared to a conventional setup, very peaky, very small powerbands, etc., just what a heavy modern day car/truck needs lol. Why sacrifice so many things when it can be done properly. Just because you can do it doesnt mean you should.

Check out this power curve by a "tuner" who was on the forums here for a while, uh why does it make stock power at redline????

Heres a stock truck with rods/pistons on 17psi with a properly done smaller front mounted turbo, the above STS sheet was on 22psi

Just to be clear I don't want an STS kit, never plan to use one, and agree a rear mount is not the best choice. *shrugs*

You're not trying to convert me to anything I'm not already aware of here. Your dyno graph from a "tuner" as you call them, clearly has problems maintaining boost in my opinion, probably either an undersized turbo or some other issue with that system. Reminds me of undersized turbos on other engine graphs I've seen that "hit 29 psi" but would only hold 20 at redline (on a 4 cyl!). I have no idea what they did based on a dyno graph alone though so *shrugs* I can only guess.

I agree with all the statements that a front or near engine mount is a lot better whenever possible though :). If and when I ever put a turbo on the 10 after I get it in my van, that is what I will shoot for. I'm only looking for around 700whp max though, give or take, so it would be a low boost setup. Thanks for all the great info on this site :)

Fortunately for me, I know guys that are good with these engines as well (John Reed is local to me and my brother has worked with him in the past on mr2's) if I needed any advice on what to do with it. :) Have a good one guys! :)
 
OK, I will agree that JMB Justin has years of experience on tweaking 10s and a few others as well and has done most of the R&D involved to make a bad ass 10. Thing is, just about ANY turbo, N2O, or SC system can be thrown on our trucks and make good power, STS or front mount. There are so many variables from "putting a kit together" that must be accounted for. I can say that there is NO WAY that the STS Turbo kit itself is killing the 10s and have a bad rep. I can say that you can ANYTHING CAN BE TUNED TO RUN CORRECTLY WITHOUT FEAR OF BLOWING UP!!! It's not the power being thrown at out 10s that's killing them, it's 95% in the TUNE! If you DO NOT DATALOG cruise conditions, WOT pulls and such your dynosheets mean shit! I tune LSX platform cars and the only time my customers go to the dyno is to see #'s. I TUNE NOTHING ON THE DYNO!!!!!! Nothing can 100% replicate "ON ROAD" conditions whether a load bearing dyno or not. All my tuning ( although may not be considered safe by some) is done on backroads with 3 miles straightaways and rarely ever traffic. We do a pull from idle, a pull from 40, and a pull from 70 and use the data collected while logging to correct for timing and A/F. My customers DO NOT BLOW engines unless it was a failure of some other part of the system (ex.)injectors (rare), fuel pumps ( NOT SO RARE), ingnition system ( occasional)

I believe these sytems that " Kill V-10 Viper engines" are just never tuned correctly from the get go. I can also say that just because someone can afford to buy the tuning software, does NOT make them a tuner!!!!!!!!
You have to know how to use the software and also know what the engine is wanting by understanding your datalogs. ;)

Ok, since such funnyness, please enlighten us on your philosophy. Do you not think tuning affects an engine blowing the F*ck up? Anything from a 1.4 liter Kia Rio to a 1600hp Pro Mod all have common tuning as with any engine. You have to supply a CORRECT AMOUNT of AIR/FUEL as well as TIMING ADVANCE suitable for what the engine desires to run safely and with performance. Bet your ass I could turbocharge your weedwhacker with a safe A/F ratio. Might be funny looking with MSD igntion and an electric fuel pump, but it can be done! TUNING IS THE KEY!
 
funny that nobody has successfully tuned an sts truck?

shit don't work on the 10's. how much more proof do you need? EVERY ONE HAS BLOWN UP... forged, or not, fuel systems, or not, the works...

I don't honestly think that for one second it is STS's fault? There were only a couple STS systems that I can find were ever on our trucks? Does that make it a fact that an STS or any other rear mount sytem will not work? Again, forge the engine all you want! Build the parts out of titanium if you want, if the tune is not SPOT ON you will detonate,ping, knock, preignite, whatever the F*ck you wanna call it and that itself will kill the motor. Kinda mathmatical in most aspects.

Add air forced into the engine with postive pressure vs. barometric pressure (vaccum) = Adding a fuel system that can supply enough fuel to supply the FI air with a (SAFE) air to fuel ratio.

Ok, now your SC belt is slipping, but you are feeding the engine with enough fuel to supply the SC at normal operation= Suddenly Rich condition

Ok, next scenario, your are full boost and one of your twin walbros's gives = Lean condition and boom!!!!

Next scenario, Vec 3 or factory PCM has a sensor gone out or giving false Map signals to the PCM or Vec 3 inducing another catastrophe.

Another scenario, you do your install with a complete kit, fuel pumps, injectors, 2-3 BAR MAP sensor and fire your truck up and take it JOE BLOW tuner that never scales the injectors for the new lbs./hr rating. BOOM!!!!! Blown up!

All I am saying is there are so many variables that can affect a FI or even a
N2O install that can kill and engine and not be the engine's fault, but rather a tuner's lack of detail that can spell BOOM the first time the pedal is mashed.;)

But.............you didn't stay outta this Tony so speak your experience as you are entrusted by many on this forum. I don't claim to know it all by any means and have nothing against you (AGAIN) and admire what you do for the Viper Truck and your dedication, but when subjects come about and you fail to provide knowledge or answers it really helps nobody? Isn't that why you are a Vendor? To provide expertise on the Viper 10 cylinder engine? I know sales is most important in business, but if you are gonna come into threads and never provide any info, than WTF? I would love to learn what your outlook is on the subject. I know Torrie does your tuning, but do you actually understand what he is actually tuning? As him about the top HP/TQ producers in the world are using for systems and you'd be surprised at how many are rear mount! I'm not just talking Lambos and Ferraris for obvious rear mount engines, but so many Viper Cars, Mustangs, Trans Ams, Vettes, etc. that do produce the numbers on the track! Sure not all kits on the market are worth a shit, BUT most can be tuned to work efficiently and make good power, with the right Tuning and supporting mods.:dontknow:

I don't think anyone is disagreeing with you. Justin basically said that tuning a 15' long, 5000+ vehicle, with a rear mount turbo system has proven nigh impossible. Can it be done? Maybe. Is are there cheaper, better, higher power producing options available? Yes.
 
I gotta more or less get something out before I can yak any, gotta have the deal done and producing before folks is gonna believe, and I understand that, so finishing up a few and inventing a few

but here is some carbon covers we jsut had custom made for a fella

150 shot is max... 100 would be a safe "have fun" shot and be comfortable, imo...

I'm gonna question that my little viperqueen. I've heard rumor, of a certain red truck, maybe spraying a 200 shot
 
Hey Venemous, tell you what. go get you a STS install it on your truck, tune in and drive it for a year. if it makes it that long ill be suprised. not one has lived. Scotty's lived the longest even had 3 or 4 people tune it Sean Roe included. It still ate two motors. Prove us wrong.
