I'm pretty surprised more people havent commented on this, esp when we have pages and pages on what oils to use & where can i buy tyres from etc etc etc.

I tip my hat to Ron & Randy woods for going through with this project, developing a system that looks top quality & will increase power a good 40% or more.

Amazing workmanship, the cost alone to develop this system must have been some serious fold, let alone the time, a labour of love for sure.

Respect!

Very interesting.......Wonder how much :icon_scra it'll cost.................

[HADI-ZR1]

Randy is Great guy, i spoke with him about his products, i bought many stuff from him for my Z.
He once sent me product before even i pay him, he wanted me to collect it before i fly to czech. the Guy who i can trust!
i will buy his Supercharger when time come up ( if it is not over priced) Lets see.
I perfer Supercharger over Turbo! i always said.:thumbsup:

I am just not a forced induction fan on cars that were NA from the factory.....Don't get me wrong, these cars are awesome and have amazing power. Just not for me. To me, Bobs 427 stroker or Als 441 are more impressive. Just my preference, not a knock on the cars.

There used to be a saying, there is no replacement for displacement. It's false. It's boost. Now a 402 with a screw on it, now we are talking!

Less than a rear mount TT was the last Randy said.

Come on Kurt, be realistic. How many people can talk boost. And plus Randy isn't exactly very active on any of the boards or out really promoting it. I had been talking to him about a kit for a customers car, but gave up after i never heard back about the intercooler fab.

[Ccmano]

I wonder if this will spur a race to market (the ZR-1 market) between Raptor and SRP? A little competition is always a good thing in my book.

It looks well engineered. Tuning will be the key. I have done both Turbo and SC systems on other cars and I have to admit I like a SC better because of the power delivery.

I have to agree with Jeffvette, until you've experienced what boost can do you have no idea. Cost remains the question. We'll see.

I'm not sure what the comments should be? It's awesome they are coming out with the product. However, there aren't really any details yet to comment on?

Also, everyone puts oil in, and tires on, their car.

[Eric870]

What kind of power boost can we expect from a supercharger?

[Jeffvette]

I have to admit I like a SC better because of the power delivery.



All those people with Sumitomos won't be able to put the power down!

[USAFPILOT]

I like it...just cant afford it...especially since he is located in Chicago. Maybe a turn key system sent via Fed Ex with really good instructions that a Novice can follow and have no troubles? Didn't think so.

[Kevin]

i'm surprised they can now. With the stock CR and open deck I wonder what kind of boost we can run before something goes boom

[A1990]

These projects take a long time to finish. The Raptor project has been talked about for going on two years now. Not a knock on these people, it just takes a long to time to get to a finish product, let alone a marketable product. Will Randy's be a one off? Until someone puts a price and delivery time on these the response will continue to be somewhat cool

Easy answer to the CR problem. Buy one of the higher milers that people seem to want to give away and rebuild with larger cubes and lowered compression.

clearly, however this is not something that everyone wants to do

I agree Kevin. Just saying that if you want a TT or a supercharged LT5 that is your best option.

Gotta pay to play.

[Pqtaces]

The only problem with turbos is the lag. I love the great throttle response these cars have... any lag, no matter how small drives me crazy.

I do not have any experience with supercharged engines. Is there the same lag problem?

[scottfab]

. Maybe a turn key system sent via Fed Ex with really good instructions

That would get my attention also. A bolt on kit would be great. Meanwhile looking forward to the posted price.
Looks great even though I can't follow the pipe flow from the pic.

I bet once the dyno numbers are in the price will be set.
I definitly like this soluton over upping the cubes. Next best would
be TT and last is juice.:dancing

[Kb7tif]

The Lt5 needs something new. Cant wait to see this and some installs.

[scottfab]

looks like the air intake is where the battery goes. Two questions.
1. Where did the batter go?
2. Wouldn't that be hot air coming off the manifold?
3. The TT Lingenfelter had two turbos, each the size of this SC.
Will it be enough for >600HP? The TT was 800HP as I remember.

[4DSZR1]

All those people with Sumitomos won't be able to put the power down!

I resemble that remark :dancing:dancing;)

[HADI-ZR1]

Not aginst TT , But SC is easy to play with it, I am sure the twin S/C for Lt5 as Randy post in His web, will be made too!

Before year ago, Randy told me the boost will be 5-6 PSI .
Price around $ 6000 -$ 7000 , ohh yea will be cool.
But hey , not bad to make +100 HP for Stock 350 engine :o .

Now how much $$$ you need to add +100Hp by Stroking your Lt5??
$ 15000 or 20K ?? ask yourself!. and your engine will loss viginity LOL.

[95ZR1#418]

I think I need one...:mrgreen:

[8upZR1]

I am anxious to hear someone with real world experience with this kit. I have no experience with the rotrex but I used to be heavy into Mustangs with Paxton Novi2K blowers. Biggest limiter on the whole deal (other than CR and shite pistons) was always belt slip. I went from 6 rib serpentine to 8 and then to 10 and thought I had slippage licked. Used all the tricks like manual tension and SC belt VHT. Then moved up to 2" wide cog and gained 8 PSI on same pulley ratio. Cog is the way to go for SC motors but there just aint no room in the LT5. For those with stock CR and 5-6 PSI this kit should really kick.

[rkreigh]

the rotex is a very efficient blower which doesn't take much to spin so I don't think the belt slip problem will be as bad

the rotex is a bit small and flow limited but will make substantial enough power that hooking it up is the real challenge

anything much above 600 rwhp takes some big balonies to put the power down

even at 500 rwhp I'm more traction limited than I would like

[A26B]

Here's an Excel boost power calculator that I made during the ZR-1 TT development. It correlates very well to the LT5 and the LT1 turbocharged dyno results.

Note that the base hp used is dyno software corrected to std pressure of 14.65 psia (sea level) I have set the actual atmospheric pressure to the same altitude/pressure of 14.65 psi. In the real world, hp results will be less at any altitude above sea level. For example, in Las Vegas, @ 13.5 psi, the "real" base hp is 366.

It should also be noted that this is for a turbocharged engine. crank driven superchargers will vary, but all will consume crank derived hp to create boost, so supercharged hp results will be less than what indicated here for power at varriable boost pressures.

Most important, is the amount of boost that can be safely applied to a stock LT5. My opinion is not more than 5 psig. Even at that, it better be done right & maintained right or head gaskets will fail. All said & done, with a turbocharged, stock LT5 @ 5.0 boost, you're in 415 power neighborhood for a whole lot less money & with stock driveability and a significantly better peak torque curve.

Not aginst TT , But SC is easy to play with it.

HADI,

Please explain, I am all ears :confused:

[RHanselman]

Yep but not less than the rear mount single turbo system ;)

[rkreigh]

bobl g and pete made up some very cool liners which are specially made to essentially make the lt5 a "closed deck" engine with the proper cooling holes

this was used on bob's new car. although not as strong as the haibeck "block insert" which is very stout, it's an interesting alternative

these two options make a low compression FI LT5 a very interesting project

I'm also interested to see if nelson racing does a billet block they have been doing some custom cnc machining and have dome some interesting projects (albeit all very expensive!)

I defintely disagree that the modern turbo systems are laggy. just the opposite, a belt driven centrifical blower "ramps up" the boost a bit slower than a modern ball bearing turbo system with an efficient design.

the centrifical superchargers make a very nice "linear and progressive" power, the turbos "hit very hard" and the torq curve goes straight up when the boost hits

while it's true the the "old" turbo systems on smaller displacement engines had alot of lag the v8 has quite a bit of exh energy to spool the turbos up very quickly. so quickly in fact that "boost by gear" controllers are a big enhancement to plant the power

like to see what TWO rotex could do on the lt5

wheel to wheel did a built LSX motor in a nova and made some very impressive power, over 1k at the wheels !!:dancing

[Billy Mild]

Did this kit ever get made?

[gbrtng]

There is a TT car near completion at Corey's shop. I think the completion holdup is the
custom ECM.

That's a Raptor twin turbo. Only one supercharged car.
