My vote is to keep the twin-turbo stuff for the truly bling bling customers and deal with those situations one-off. I don't believe there is a market that will sustain your business with the LT1's and twin-turbos.

I would say come up with a kit that is simple to build (for you), easy to install, reliable and at a good price. I've spent many a night over the last few years reading in this forum only to just get completely confused about performance of a turbo setup and log vs. header manifold design and everything else that goes into it.

It would be nice to see something that is well put together and has some adjustability (so as folks upgrade the bottom end, they can take the boost up too). If you only want to cater to the racing crowd, then I think it's really a one order at a time business.

My vote is a single turbo design that keeps A/C and makes 500-550rwhp (basically keep up/beat the z06 ) and isn't loud as hell and ofcourse could be street driveable. If it ends up being a log, but makes that power, than great. If you get enough of them out there, the quality/performance will sell the product for you. If someone really needs more than 550 to the wheels on a daily driver, I'd say that person is a unique customer and is willing to pay more and understands they have to pay more.

The lt1 platform is 12 years old now, and these cars are cheaper and cheaper to find. I can't see many people investing significant $ in this platform in the future. I think there is an opportunity for something in the 2500-3000 range (or cheaper) if it can meet some of the criteria above. If you can come up with a cheap/quality combo (and do it in a way to keep it simple with good quality and high volume and have enough margin for yourself through it all) I think you could have a winner.

I think a good example of this are the LPP headers. I got the headers for right around 500 w/ypipe which are stainless. A few years ago, the only option cost at least twice as much. take a look at his post on ls1tech. I think it's got the largest # of posts I've seen and the first batch sold out really really quick.

Ultimately we all vote with our wallet, and that's a harder one to gauge in this space. lot's of people would love to talk up a purchase, but it's hard to pull the final trigger. This car has been in my family since new and i have way too much in it to ever get rid of it, so as the years go by, maybe I'd put one on, maybe not. All depends on if the car will stay driveable for me and I can continue to have fun with it.

 

Thanks for the detailed input!

 

I'll admit to not reading this thread. But are you guys talking true twins or compounds? I run compounds on the truck and it's great. I might do boost some day and compounds on the car seem like a cool idea.

I'm with the majority on this one. Personally I think twins were more ideal for people with 6 cylinder vehicles to get things going and then get into the greater boost level of the 2nd turbo to help fight against turbo lag.

With V8's and usually a healthy setup for those going the turbo route, lag is not really an issue, and single Turbos are ideal.

 

For the auto guys, picking the right converter helps A LOT with lag on a single car. I had VERY little lag on my setup, even with the stock heads/cam.

I don't think the market is there right now for a twin kit honestly. Keep building the singles and if someone really wants to pay more for a twin kit then let them and build it for them at the time. Really a single kit should have no problem pushing into the high 9's as long as the rest of the car can do it.

 

lol wtf isn't his valve backwards? You want it to open with pressure applied to the diaphragm, not close.

 

The guy has a G/N and is a pro.
He's using CO2 to actuate and control the opening of the valve, not manifold pressure/vacuum.
Here's his car in action.

He has run (at least) 5.8's at 115 mph in the 1/8th mile.

 

I vote no...having been there. Too much complicated plumbing, re-routing, and relocating of things for your average bolt on type customer.
