I am now officially the local mule for the Roe tuned STS SRT-10 turbo system. They'll be using my install to write the installation manual for the rest of the kits. As such, Rick Squires is going to do the install himself. The goal is a solid 600 rwhp on an otherwise stock engine. I'll have variable boost capability from 4 to 8 lbs. The Tahoe on their website sounds awesome. I'm anxious to hear what this V-10 will sound like.

That is very cool. :thumb:

Curious about your traction plans. :eek:

Hell yeah! Definitely post up pics :headbang:

that is cool. better post what the outcome is.

The truck has a 55/45 weight distribution so not too bad. It has a Dana Super 60 limited slip rear end. The trick rear suspension has built in traction bars and shock absorber on the differential housing. For traction, the tires are really the weakest link. Bogart wheels near you in El Cajon has designed a set of 18" wheels to clear our brakes so I can run Nitto DRs. But, if the tires hook, I'll need to watch my clutch.

shouldnt you make around 40-50% more power with forced induction? dont know much about it though. 500 hp stock should make around 7-800hp with forced induction right?

fogle, it depends on boost. I've have heard on a turbo setup add anywhere from 15-30hp per lb of boost. Just estimates though, dyno is the only way to know.

Thats going to be one bad ass truck! Post up results when its finished.

Dayum!!! That is going to be sweet!!! Keep us posted.

Sorry not to reply sooner. I've been out of the country. Just got home tonight. In fact, it's 1:20 am and I have jet lag. Couldn't sleep so I thought I'd check the forum.

You're right it'll make around 700 hp on 7 lbs. of boost. The stock internals aren't made to handle more boost than that. 700 hp at the flywheel comes out to about 600 hp at the wheels (rwhp). I'll be running 4 lbs most of the time and can have all 7 lbs at the flip of a switch.

You should be making 600rwhp in your sleep with that thing. SRT-10 vipers with a simple paxton kit and some tuning are making over 700rwhp all day long on pump gas. Those motors will take a heck of a lot more than your giving it credit for.

You can always give it more boost and a more aggressive tune but we're talking everyday driver, stop and go, long cruise reliability here in a relatively mild street tune. All the Viper experts from John Hennessey to Sean Roe to DC Performance to Rick Squires agree that 7 lbs is max for a stock 9.6:1 engine that you intend to drive to a long, healthy old age. At $15K - $20K for a stock engine I can't afford to go breaking this thing every other week. There are guys who have pushed their trucks further, some are still running and others blew up in a fairly short time. I prefer to keep mine running for a long time.

that is sweet. I would love to hear a V-10 turbo.

I hope it sounds better than the blown V-10s. Vipers make the most horrible exhaust note I have ever heard. LOL My buddy has a Viper with a twin-screw and it sounds like a friggin Kobota tractor. :barf:

The turbo should help out with the sound if you run a small muffler after the turbo. That's what most of us GM truck guys do. Makes for a more pleasant daily driver and really doesn't hurt power much. You can always run a cutout before the muffler if you really needed to as well.

The power should be awesome if you have ways of tuning. Do the trucks use the same chip style programing that the Vipers use?

I'm anxious to hear what it sounds like. These V-10s definitely don't sound like a V-8. We'll see about "sculpting" the sound after it's up and running. So are you pleased with you STS set-ups? By your numbers it looks like they run pretty hard.

You'll be happy with it I think as long as you add all the extra pieces like the FMIC, fueling and tuning. Get all that nailed down and the kit rocks! It's just like any other mod though. You gotta put it together right :)

Ohh, be very careful with water too. The sock won't always save you so make sure Rick takes that into account. I lost a motor due to water and being stupid. :(

Keep us posted man :)

Here's an update on my turbo install - there is no update. We've been waiting for some parts from Florida which finally shipped yesterday. Hopefully they'll get here by the end of the week.

What are the plans for fuel management?

I sure hope it goes better on the SRT line than the HEMI line, oh STS swore to god they had it figured out for the HEMI. So far I can say I know of two that have had blown engines and about 4 that just gave up on STS coming up with a fix for the fuel management on the HEMI, they did their own R & D, and their research yeilded a ton of improvements. Its just like I said over a year ago..........you don't just slap a garrett on, add an intercooler and a extra injector set up. I don't mean any harm here but I'd be real scared of being the guiena pig for STS knowing what they did with the hemi engines, and I would look at routing my intake filter up over or into the bed. I also know 2 people that sucked up water and blew engines!

Update? I could have walked the parts from Florida to you by now. :jest:

Picked up my truck Tuesday evening and have been having a blast ever since! The baseline dyno was 418 rwhp and 438 lbs of rwtq. At 5 lbs of boost through the stock exhaust manifolds and four stock cats it pulled 548 rwhp and 592 lbs of rwtq. Next week they finish the methanol and two stage boost installation and we'll re-dyno it. With 8 lbs and methanol injection, they are guessing another 60 to 75 rwhp. I'm really excited at how flat the torque curve is. I'm getting 450 ft/lbs at only 2,200 rpms and am at 500 ft/lbs by 2,500 rpms. It stays at or above 500 all the way through 5,500 rpms. Horsepower stays around 500 hp or above from 4,500 past 5,500 rpms. Lots of usable power and believe me, it feels like it. This thing flies!

The turbo sounds awesome. It sounds like I have a Pratt and Whitney jet engine strapped on the truck somewhere. I had people actually roliing down their windows in traffic to listen to the engine sounds. Some of them yelled through the noise, "That thing got a turbo? Cool!"

At 5 lbs it's extremely well mannered on the street. Very drivable even in stop and go traffic. I'll post some video by tomorrow if not later today.

BTW, the modern hemi is a different animal and can't be compared. No one has effectively cracked that computer yet. IMO, DCX has to support the aftermarket much better than they have. They need the SEMA crowd to continue to sell cars and trucks. Hats off to Ford for figuring this out a long, long time ago.

Congrats Big Asp- Sounds great. That's GREAT numbers!!
Can't wait to see some video.

BTW-as for no one cracking the hemi... it's been effectively cracked. It can be manipulated any way needed. ;)
Mine has a custom tune for the cam and is now getting the good mods and tune. I had to sign a couple nondisclosure agreements so I can't really say anything yet (I know that sux but hey, I had to sign it and I'm getting some good stuff out of it) but come end of October- things should get very interesting for us hemi owners.

That's good news! I know a lot of Hemi owners that willl be excited to hear that.

What would the chances be of the STS kit working on a non-SRT v10 in a truck? Besides the obvious manifold difference. ;)

It should work on any engine. However, it'll have to be fabricated to fit and then tuned for that specific engine.

Video!!!!!! Now!!!!!
