Blow through turbo setups?

Recommended Posts

It is funny how this subject is rehashed over and over. Tony D always tries to set the record straight on the drawbacks of blow through carbs and to use EFI. There is no one that I know of who has as much experience with blow through set ups on Zs. For myself I will probably get my blow through supercharged running one of these years and learn the hard way that I should have just used the triples normally aspirated. But what the heck, some of us are just too hard headed to listen to the experts on the subject and can only learn by our own mistakes.

 Guys I'm sorry, I know this has been beaten to death, but I'm new to this whole scene. I realize this thread died a long time ago but I'm curius as to if there is a improved method to blow through triple carbs these days. are there still hard heads still running this set up? If so can someone enlighten me. If not, what is the best way to turbo my engine if I currently have triple mikuni's that most say will not work with a turbo set up. I just want a semi daily driver that can get me there fast as hell, or faster.

 

So are my options? ....

 

1. The ITB with the engine management set up is attractive but what kind of street speed will it deliver?

 

2. How much of a nightmare would converting to efi with turbo be?

 

3. What other turbo options would I have that I don't know about (if any)? Is there something like a bolt on turbo manifold with some kind of fuel management/delivery out there?

 

Again, please excuse my lack of knowledge on turbo, and keep in mind I have an expert that is going to get me there, I am just waiting in line for him to get to me, we have discussed this over the phone but again I am eager to start learning what my options are going to be once he gets to me.

There's a guy in our club (Ontario Z Car) who just made over 600 Hp on a 3.1l L28 with a triple Mikuni blow-through setup. No EFI. I wouldn't have believed it if I didn't see the dyno sheet. So it can be done. I don't have many details beyond that though.

Thanks Nigel, 600Hp wow, I'd die an early death with all of that. Actually I don't desire the absolute fastest beast, just fast for me, if that makes sense.

 

Anyway, How can I get in touch with this fellow?

"if there is a improved method to blow through triple carbs these days."

 

Yes, I got an e-mail from Newton just the other day, the laws of physics have changed and don't apply anymore!

 

Asked, Answered, Documented: Search and Read.

 

The "Slow" RS-Okinawa car had 444kw (Bosch Eddy Current Dyno) in 1987, no computer controlled ignition, no efi, no crankfire timing.

LOL!!!

 

Point WELL taken Bro.

 

I've been introduced to a  fellow z driver  who recently dyno'd 640Hp with his set up, so hopefully when we talk he will shed his experience about the science of blow thru.

 

Oh and I heard back from Whitehead performance, and was informed that they would be glad to help mewith the necessary hardware. Good news Indeed.
