LS& Supercharger

[scauto]

We have a customer with an LS7 looking for a supercharger kit. Is anyone currently running one and if so what brand, part number and any recommended parts? Thanks for the help!

Mark Stielow has an LS7 with LS9 Supercharger works with LS9 heads. Harrop has a kit for LS7 heads. http://www.harrop.com.au/sc_detail.php?prod=HTV2300FDFI
Thomson is the only authorized dealer in the USA for Harrop. http://www.thomsonautomotive.com/


I think Whipple has kit for LS7 as well.

Thanks Jeff, for the response. I will definitely check these out.

The Harrop is just a TVS, IIRC they're very popular in Australia.

What is this going in? Is hood clearance an issue? Superchargers are almost like tires nowadays, there are about 10,000 different ways you can do it, twin-screw, centrifugal, depends on what you want.

How much power do you want, what belt drive do you want, what do you want it to look like? What accessory drive do you have?

Whipple or Magnuson is the easiest to deal with here in the US imo. I supercharge about 400+ vehicles annually at work, we almost exclusively use TVS stuff, it's 50 state legal, and the most reliable way you can roll. .02

Thanks Mike. The supercharger is going into a 70 Chevelle. I'll check with our customer and get some more specifics on what he is looking for.

I disagree about Mike's comments about Harrop, but it is own opinion. Actually, there is a few other Harrop TVS2300 on Lateral-g.net as well. I own a Harrop TVS2300, which I bought back in 2008. I did contact Magnuson and they refused to sell their new TVS2300, because my 67 Camaro wasn't a new car. Actually, Magnuson didn't start selling TVS2300 Superchargers until February 2009. Harrop is great company to work with, because they help out the customer. The only disadvantage about Harrop is that they are in Australia, so you might have to wait a few weeks to get it. Magnuson was also bought out in 2010. http://bangshift.com/blog/magnuson-products-bought-by-private-equity-firm.html

Although, I decided to change to an LS9 supercharger for my 67 Camaro, because of the custom work that was done in metal on my dash. I still own the Harrop TVS2300 with a custom Pulley setup from Wegner Automotive, so if your customer is interested in that, then I can give him a great deal on it. The unit is polished as well.

Last Summer, I test drove Brian Thomson's Chevelle, but it is an LSX 454 with LS9 blower and LS7 heads. Idles rather nice around 650 rpm, you can't tell it has this much power. There is no vibration as you would get in big roller cam engine. I had a 383 small block with full roller and 12.5 to 1 compression, it would rattle the entire car. Brian's drives rather nice, but he has rubber engine mounts, well, if you saw Camaro XV thread it has those mounts as well. My 67 Camaro has new rubber mounts as well. (Brian said that the Harrop TVS2300 has been on his 72 Chevelle in the past)

Since your customer has an LS7, then I recommend that you tell him to upgrade to oil squirters. Brain Thomson recommend it for his LS engines that he does it at his shop.

OP,

List of exact goals and parameters you're working with. Where the car is, what he is doing with it, octane the customer thinks he'll run, octane the car will really see, horsepower, times he expects to run in xxx environment etc.

Depending on the accessory drive, and what it actually is, you can go several different routes, all of which will yield success.

Magnuson is a big company. If you call and say I've got a 67 camaro that throws up a red flag that it's a custom job, and they may or may not be getting accurate info from the customer. Unfortunately this is the World we live in, so in Magnuson's defense I'm sure they've had 10,000 times where they had to send someone free stuff because the purchaser made a mistake on the accessory drive setup they had or something.

Basically figure out which port heads you're going to use, and what accessories you're going to use, and find out what car came with those two things, and claim you're ordering a kit for that and you wont' have an issue. You'll need a custom tune anyways, so the tune is irrelevant.

You can also order a hot rod kit, which is just the blower, then you can order the larger heat exchanger / fab one and you won't need the plastic molded resivoir for XX vehicle and you can just get a tank. The TVS units all use 5/8 heater hose to circulate the water/air intercooler system, which is also nice, and if you're looking for a little extra bling it is wildly easy to convert it AN, you can use a low pressure flexible stainless or kevlar for a really pretty install.

Mike, you seem to have things a bit confused. I never bought from Magnuson, because the customer reps refused to sell it. The year was 2008! As for the accessory drive it was being developed by Wegner. Casey Wegner developed for Harrop and later on developed one for magnacharger.

Magnuson should have provided those answers to their customers, because I got those answers from Harrop.

Post was directed at OP, Original Poster.....lol.

Magnuson sells bolt-on packages with EO compliance numbers, warranties, and headache-free blowers. Don't be surprised if you call them and they shy away from something that doesn't fit that model, which is why I'm trying, in my posts, to tell the OP how to figure out what he needs.

I still have no clue of a power goal, etc. If it's "I have an LS7 and am looking for 639 horsepower to best an LS9" (I just picked a random but common goal I hear from people) there are about 20 ways to do that easily, etc.

You could also go turbo and won't need to change pulleys for different boost levels, have no belt throwing issues, do boost by gear/time, run the same intake.....

What rods are in that motor? Is it resleeved? What are the power goals?
Titanium factory rods are not the best choice for boost.

I would also be weary about boosting on the stock sleeves that are even prone to cracking when pushed hard running N/A.

This is my turbo setup with a/c in progess. Should make 500rwhp with a tiny amount of boost and 900rwhp+ or whatever the factory rods will hold set on kill. All adjustable within the car. I'm running modified factory truck manifolds that I got for free and added V-bands. C5 Vette accessories, Holley a/c bracket/compressor.
