348 Twin Turbo dyno results

Pics of the engine setup ? Very interesting.

 

That's quite interesting, do you know how that setup compares to this one in New York which claims to have 750 horsepower? https://web.vinwiki.com/#/vin/ZFFFA36A8K0082640

 

Thank you, that's very interesting, do you have any plans for the future with this build?

 

Doesn't look like it would be too hard to build a -sandwich- style air to water under the plenum(s). Could keep most of it as-is that way. 11psi all in at 3700 or?

 

Will you work on making the hp and tq lines smooth like the original ferrari ones?

 

He already answered your question in a way. When it's intercooled and IAT's drop 100+ degrees it will take a bit more timing and smooth out the graph.

Nothing abnormal about it as-is, non intercooled/turbocharged.

 

Need some videos of your 308 that has to be a blast!

 

Looks like Tial waste gates and oil cooled turbos. Where did you tap into the oil system? We're talking 1.17L per side so small turbos are in order, I assume you used something like a TD04. Problem is always a large enough AR to hold boost but not so big the lag is annoying. Maybe a small twin scroll from a European car? I also do not see the original maf's what replaced them for metering air in? The standalone ecu you used, I assume the original ecu plug was re-pinned to mate to it. Using stock injectors, they are kind of small, did you add an adjustable fpr to compensate?

Non turbo cars with a turbo added can live a good long life as long as one does not start thinking of it as a turbo car. 350 at the wheels on a Dyno Dynamics would be plenty. That's roughly 100 more than stock. I'm sure one can get 8000 hp but for how long is another question.

Awesome man good job, personally I am interested in this topic

 

Did you use an unterminated loom for the M84 and splice it into the existing ecu wiring or did you wire it to a Mortonic plug that mates with the existing engine harness?

Ahh those are water lines, I assume you T'ed off the radiator return somewhere then, the picture looks like a braided line but most of the coolant plumbing is rubber which is why I ask not obvious where you tap in an an fitting unless its new fitting at the radiator itself.

Routing of that pluming worked out great, is the waste gate dumping to atmosphere or into the exhaust?

What is the little breather filter on the back of the intake box?

 

Ahh using the oil jacket only hence the steel lines. Where did you tap the turbo oil from, oil filter sandwich plate?

 

Had you considered a water/methanol injection system? They are relatively cheap.

 

Hey man, really nice job on the turbo conversion. Must make it a pretty nice and exciting car to drive now...

I could not recommend the Link ECU enough, I have been using them in my race cars since the 90's.
They are a nice versatile package, we have tuned many many cars on Link's, the current G4 series are really good....

I assume you'd just use the manifold vacuum/pressure for the fuel map, that's what I've always done with my turbo engines......

Hmmmm food for thought, I was just going to fit a Link to my 348 and tune the best we can, we have very good 98 octane fuel in New Zealand here, so with that we should be able to get some timing into it, was hoping to get another 30-40hp with a decent tune and upgrading to modern 250cc quad spray injectors.
The original injectors in the 348 are 184cc (which is what mine flowed under test recently) which is pretty light, no wonder they run so much fuel pressure.

What injectors did you change to?

 

Okay, yes that makes sense re the injectors.....Yeah I guess if you were going to step things up you'd be replacing those, especially for an E85 tune...

You've got me thinking now, my friend is a turbo re-conditioner, he does a lot race car turbo work, I think turboing the 348 might just be the way to go, I think I might start doing some more research into this...I'm keeping my car so not really worried about keeping it original in that respect. Definite food for thought....

Have you got any video of your dyno runs? I'm always a sucker for a dyno run!!

 

Nice, I'll be looking for a link around new years for a 348 project, will give you a hoot

 

Agreed. Flex fuel is where it's at.
