Is there any interest in a turbo kit for 308's

sure, as long as its not $30K like the Norwood kit done on the 308 as seen in this month's Forza......

 

I agree, it wouldn't make sense to put that kind of money into a 30k car. I'd buy it if it were 5k.

 

the big wall we all seem to run into is that unlike newer cars with modern EFI the 308's have nothing that can handle the FI. so a complete update to modern EFI and a decent management system adds to the base cost.
sure a simple turbo package i.e nuts bolts & hardware can most likley be done for around 4k but tacking on the EFI and mass air systems just upped it another 5k easy.

hard to see how it can be done for less than 10k retail, unless you're going to give up nearly all profit and do the R&D for free.

just quick and dirty from the hip, not ment to discourage. by all means if you can do it go for it! i'm sure you'd find a more than a few interested.

 

A lot of people have ask me about supercharger kit and it's ths same problem, the EFI adds 3K and the kit needs to be in the $8k-$10K range...pretty dear.

I think about the cheapest way to do EFI is with a haltech E6X....it will plug into the crank triggers already on the FI 3x8 cars and fire the 2 distributors, all for about $1300...but then $300 for injectors, $500 to convert the intake, $100 for a fuel pressure regulator, $500 for fittings and lines, ........I guess there is always megasquirt. I know 1 f-chatter is getting ready to try one, they seem a bit primative, but we'll see how he makes out with it.

 

I'm seriously interested in a SuperCharger kit, though that's not what you asked. I'm more interested in boosting the low-end torque which I would use everyday versus the high end where a turbo contributes.

Would a turbo or supercharger be feasible on a stock 1977 carb 308?

You can do a blow through turbo with your carbs...it doesn't work with a supercharger. A supercharger needs the carb before the blower...I saw a pick for a 2V 308 with the blower on top and a holley on top of that.

 

Another thing to think about is, I'm pretty sure, Norwood already sells a kit for about $7K...minus the efi stuff though.

 

I talked with my mechanic this morning about supercharging my 308QV (he was working on a supercharged BMW at the moment) and he's ready to do it. I think I may be ready to do it too...

 

turbo kit is 11k and the EFi is 9k, still too much for me.

 

It was not a kit. I told James at Norwood exactly what I wanted and he did it. They asked if they could use my car on their website to demonstrate what could be done to a 308 and I agreed. My car apparently lead to their kit development. There was more done to the car than mentioned in the article that contributed to the 30k. lots more........

Cheers

 

Don't do it, Mike. Really. If you do it then I have to do it and that will empty out my savings fund I have going for that little brown 308 up there that you and I know about.

 

I just read that article. I cannot imagine my car with that much torque. How fun would that be?

 

lots of Fun! Look me up if you are ever in Vegas Dr. T. and you can see for yourself. I warn you, once you get her head snapped back, you will want one, whether turboed or supercharged it doesn't matter, they both make boost!

I just spent 10 days in Kuwait doing some military flying and had to take her for a ride. What jet lag? I am full of adrenaline now! the good thing about the car like Zach indicated is the power is very nice and linear the way I wanted it making the throttle very nice for cornering.

Cheers

 

LOL!!!

 

Yes, now prepare to feel the power of the dark side.....

 

Believe it or not I just booked a trip there yesterday. I am taking my office staff Mar 2-5. Can I buy you lunch?

 

Hey, MK e, are you saying that with the stock Webbers, you could run the boost directly into the carbs from the turbo.....without putting the carbs in a pressurized box. Wouldn't that blow the seals out on the carbs?

 

I will buy you lunch and let you drive it! I see a turbo in your future.

PM me and I will give you my phone.

Cheers

I've seen it done, but it wasn't crazy boost, under 15 psi I think.

 

deal!

 

Can someone correct me if I am wrong on this. Let's say you were going to make a single turbo system for a carbed car. All you would need then is 1) turbo charger, 2) correct exhaust modifications to make it fit, 3) correct plumbing to route the air intake, 4) correct plumbing to route the air into the carbs, 5) an oil supply for the turbo charger, and 6) some kind of waste gate system for overboost. Other than some things like a boost guage and some heat shielding, what else do you need to do? It seems pretty simple, and not 10k worth of stuff.

 

Thats should be about all there is to it. I think you could blow right into the stock aircleaner if it had good seals. But one problem that was discussed on another members car was that his turbo was mounted way down low and had a hard time draining oil back into the crankcase. I would think hanging the turbo off the rear head would be a good location, and "Y" pipe the two stock headers into it. Or, mount two back there and feed each header into its own turbo and run different sized turbos? The wastegate is generally part of the turbo, and vents directly downstream into the exhaust. Because the air stream will be so long between the air intake, through the turbo, and then to the carbs, I could imagine a loss of low end response, followed by a good boost of power as the turbo spools up.
