Hey Guys, I'm still lurking here and now I need some help. My nephew and I went on the Hot Rod Power Tour this year and 3500 miles later we decided to do it again every year. Since I've retired all I do is play with the Vette and the Impala. I'm looking for a winter project and would like to add some forced induction. Are there any "kits" available for our cars? I built a new LT4 engine for the Power Tour and believe it is able to handle some boost. I know I'll need pistons and probably a cam. The cam I have now is a 242/248 with about .600/610 lift on a 112. I've got the AFR 1039 heads with the 2.08 valves and will be reusing them.

My goals are to make the engine look more hi-tech and get to around 600-800 RWHP. I just need enough to beat the Hellcats.:D I know some of you on here have had superchargers and twin turbos and I would like to find a source. Also any information that would help me decide would be great also. If no kits then how about components? Header style, instead of log, manifolds which turbos and intercooler and a source for parts if no kit is available.

I'd like to keep the total build cost under $10k. Any ideas or suggestions would be welcomed with open arms and a promise to buy you all the beer you can drink the next time we meet.

I am a huge fan of Procharger with their self contained series, but the kits are no longer available. There are guys on the boards who sell complete procharger kits from time to time and I believe there is someone on the boards who found a CNC shop that was able to duplicate the procharger bracket for a good price. From there, you just have to source the blower, intercooler, bypass valve, pulleys then fab up some piping.

Coming from someone who is looking to make around the same power, I can tell you it isn't going to be easy with your setup, and depending on what is in the bottom end it may not hold up. Just for reference, I am looking to make around 600-650whp but I am running a fully forged 396cid LT1, AI 200cc heads, 600 lift cam, coil pack conversion and 1 7/8ths headers.

You will also need a very good fuel system to support that power with boost. A single 255lph pump is not going to cut it. After that, your trans will be on borrowed time until you have someone like Cahall Performance build you a pro-race 4l60e or swap to a th400/4l80e.

It isn't THAT hard to hit the 600rwhp mark with a boosted LT1, it just may not be easy for under 10k unless you plan on doing a home made Ebay turbo setup or find a used blower kit on the boards. Then, if you don't have a forged bottom end, expect your motor grenade. What are you starting with in regards to the specs of your motor/bottom end, transmission, fuel system and exhaust? Here is a break down of everything going into my setup that I can rattle off at the top of my head.

396cid eagle forged rotating assembly
AI 200cc top end kit
LTCC coil pack conversion
Modified fuel rails (TIG welded) to be dual feed
Aeromotive boost referenced adjustable FPR
CIA pro race 1 7/8ths headers
D1SC procharger with NRP (no longer in business) bracket
FSR aluminum radiator
Cahall pro race 60e
Vig 10.5" converter
Eaton Posi/3.73 with 1350 yoke (not part of the engine/trans setup, but building the rear is something you'll want to do)

Things I'll be picking up soon for the build:
Aeromotive dual 340 phantom fuel system to use in the factory tank
3.5" aluminum driveshaft
welding up a 3" exhaust and intercooler piping

I found deals on a lot of stuff and picked some of it off of a car that I parted out and actually made profit off of, but even so I probably still have about $15,000 into what is listed above. I didn't exactly do everything the cheapest way, but I did save a lot on certain parts. If I were to buy all of the above new, I'd estimate it would have cost me somewhere around $25k

A little off topic, but SSandman, what are you doing for the dual in tank set-up? I have been looking around for options beyond my 255 I have from my Racetronics kit. I'm not going boosted, but may try E85 at some point so need the extra fuel. I was looking at shoehorning a 340 in the stock location, and got with Squash about them doing a dual tank set-up, but there would have to be enough interest for them to pursue.

Fasst, I am 99% sure I am going with the new Aeromotive Phantom series dual pump setup
http://aeromotiveinc.com/products-page/stealth-fuel-systems/phantom-system/dual-phantom/

I am just waiting on Aeromotive to get back to me on some questions I had regarding the use of the product, but it seems like it is going to be the best way to go, for me. It'll solve the fuel slosh problem, allow me to use the stock plastic tank which I really like and is cheaper than most surge tank setups I have priced out. The only issue I have with it is how much overkill its going to be for a 650rwhp setup.

That is going to require modification of the stock tank though, right? IIRC, you would have to cut out a large hole and it bolts in like a bulkhead fitting. I did look at that, and it does seem like a good option and is relatively inexpensive for what it is...they also have a Phantom Flex kit with a single 430 pump. Designed for E85, but can support 800hp FI (flywheel) on gas. Would certainly be less electrical strain.

I wonder how the factory vent lines would connect. Been a while since I have had my tank down so I don't remember what's all up there. Also wonder how wiring would work. Maybe the Racetronics kit could support it?

Thanks SSandman and I think the engine will take it. I have a Dragonslayer 383 crank with Lunati 6" rods. Currently I have Mahle flat top pistons but they'll have to go. I've heard that Diamond will cut some blower friendly pistons and their quality is very good......I hear. I have the AFR heads already and don't want to buy them again. ($$$)

I did hear from some place out in Washington (RMCR) that I spoke to about blowers and they said the Bailey LTCC didn't work with the blower setup. They told me that they even spoke to Bob about it and he sent them two other units to try. Apparently the spark kept blowing out. Might want to check on that. They said they had to go a 24X system to make it work. That sux because I have the LTCC also.

I'm really wanting a twin turbo but apparently that's not made anymore. I just liked the looks of it. I'll be talking about blowers to a guy on here shortly. Maybe that's the route. I need more info on reliability, meth injection/intake temps/knock prevention type stuff. Maybe the blower is a better choice. I could keep my old Grottyohan headers.

Thanks for the insight and the reply.

The only TT system I recall was the custom setup by Keith Mease (Mease Performance Engineering). Problem was that he became VERY unreliable when it came to delivering the full kit.

But the few people who got the kit were laying down really big HP numbers.

Thanks KW. This is what I wanted to do. It just looks like it would work and happens to also appear to be mean as Hell. Probably looking at a Vortec or a Procharger now though. I just called the RMCR folks that you provided a link to and they quoted me a price on the ti trim kit that they said will hold up to 15 pounds of boost on my built engine and "they said" at about 12# of boost I'd be looking at about 250-300 rwph gains. Sounds like a lot but "they said. They also said that meth injection would be nice from an octane/detonation standpoint but not necessary at up to 15 psi. I'm sure this will be a learning experience.

I'm considering re-looking up the guy that had this setup for sale a few years back... now that I'm 'grown up a bit' (???) I'm getting interested again...



Dunno if I hope it's still out there, or not...

The guy was doing all the work himself including forming the custom carbon fiber elbow. It is all one off stuff. He drew the base up in a CAD program to be CNC'd, so I assume he would still have it. Maybe someone could try to contact him and find out what it would take to get a copy of the file to reproduce. The base would be the hardest part of the whole thing.

hopefully we can get this going again , i'am sure this would like to keep the LT1 and build on it ...

Doubt it.

This was an F-Body guy that was working on it. He has had one up and running with a Magnusson 112 blower, and has been working on this Whipple version for years. Pretty sure his last post on it was over 2 years ago.

If you're serious pm me. I know where one of the 4 kits is and might be had for what it was bought for.

The M112 is a cool fun add on. I have one on the LS engine on my 02 Silverado. I've been having lots of fun with it out here (in the absence of my SS of course). LOL
