Supercharged QV (take 3)-or is it a turbo?

I've used the M48, M600 and M800. I'll be using another 800 this time 'round.

Most of my experience is with AEM, Motec and Autronic. Motec wins hands down for overall flexibility in the system. I've yet to run into something I couldn't do with one, which has always justified the price.

interesting thanks for sharing. Keep us posted!

 

I think there are probably quite a few of us out there that would be interested in head work for 2V cars.
20-30% would be around 40-60HP, which would get a 308 into 328 type numbers.

I have owned a 328 as well and have to say that the difference between cars was huge. Adding 50HP to a 308 for an extra $2-4K is a no-brainer.

My new plan is evolving.......
2007 head work to reach 260HP (and replace soduim valves)
2008 Nicks SC kit to reach 370HP

Great thread guys!

Yeah, that's definitely fair. Please send me his address. Would he be interested in a partial head? I have a horizontal bandsaw and can cut a head into individual combustion chambers.

 

I don't have a spare 2V head, but if somebody is willing to donate the head, I'll Paypal them some money to cover the shipping costs.

On a seperate note, if I *only* want 400HP to the rear wheels do I need to port the heads or would a fresh motor with a SC get me there?

 

Yeah, you would need their coil packs but my throttle position sensor and idle air control valve are Ford pieces direct off of a 5.0 Mustang. The sensors for MAP, MAT and coolant temp are all reasonably priced GM pieces. I got the cam sensor and crank sensor from Smith Systems. A friend of mine is a sales guy for them. Their sensors are heavy duty, stainless steel and are used by NASA on the space shuttle, the military, Am-Track, etc. and they are not priced out of sight.

I have another thermostat, this time a 190F. Ford/Chevy V8 unit that I'll install with less by-pass holes and will see what happens. I cant think of the make right now but a high quality water pump with an ECU that controls pump speed according to temperature is available. If I get desparate I may go that way but I'm keeping my fingers crossed for the mechanical thermostat route.

 

Thanks Mark. I'll contact Vic.

 

Ok yeah, you need a trigger wheel. It's a 60-minus-2 toothed wheel and comes in several diameters. It's also not that expensive. If you prefer reading off the flywheel, put it on a rotary table in a Bridgeport, drill 60 holes and install 58 pins - same thing.

The 60-minus-2 gives very accurate and long duration spark control. For example: MSD stands for Multiple Spark Discharge, as you know, but after 3000RPM, when you realy need it, the MSD system reverts to single spark discharge. The Electromotive system has an accurate spark duration of about 60 degrees, if I remember correctly, accross the full rev range.

I'm sure the OEM crank sensor and the Ford "cam sensor" would work with the Tech3r. It's just looking for a steady signal. I don't think it's real picky about it. They supply the ECU with GM sensors but it seems happy with a Ford TPS and a Ford IAC eventhough the latter is not a sensor. The Smith Systems sensors were picked out of their catalog by dimensions and whether or not I needed it to be magnetic or magnet sensing. They were just generic sensors and are working fine.

I just remembered the maker of the variable speed coolant pump. It's Stewart components. Check it out at stewartcomponents.com. It looks like a nice unit.

 

Well, I have never felt anything in a 308 at those levels. I have no clue what my 9.6 CR motor with P6 cams with a blown piston put out, but it was the most I have ever felt in a Ferrari. Second most powerful is what I am herding around now, 77 GTB totally stock engine as far as I know with euro headers and gutted airbox, sans pompe de aire and the fusion reactor. It pulls harder than the QV I was in, at least in the bottom end. Which is interesting.

Before I serviced the belts and timed it, I found the rear intake cam was retarded the equivalent of about one belt tooth. The other cams were basically on thier marks. It didnt idle bad, not great, but top end power was actually better than it is now, while bottom end power was slightly worse. Kinda doggy getting it to take off, then it pulled hard up top. Now it slips right off and goes, but without any drama as it winds up. Currently it is timed at 100 degree LC intake, 90 degree LC exhaust. I suppose prior the rear intake was somewhere around a 115 degree LC. Once I have Scotts pulleys on it will be fun to move them around and see what it does.

I love the way this car runs today. It idles down really slow, purrs actually, and throttle response is instantaneous. I would hate to mess that up just to have more power. As much as I like the P6 cams, I like this current cars smoothness at low speed probably more, so I dunno about the big cams at the present time. And, unlike some of you guys, I love the carbs and the sounds they make more than I would like 400 HP and to lose that sound. So I will do whatever I can within reason to increase power, but I dont want to sacrifice low speed performance or the symphony of Webers. Plus I do want to keep a fairly stock appearance. I guess the only realistic way to achieve all that would be to increase displacement. Russ 3.2 making 300 ponies seems to make a lot of sense.

 

Not to beat anyone up but I don't understand what people like about the sound of a stock 308. To me it sounds like two old VW bugs running at the same time. The 308 is, in my opinion, one of the most beautiful Ferraris ever made and it drives like a go-kart but I never liked the sound or the anaemic power. I drove a stock 308 2V with CIS and a 328 today after driving my boosted 77 308 yesterday and I found the power and sound pathetic. The carbs add something the CIS takes away but still. What the car really needs is a nice free breathing V12. Now THAT is nice noise!

 

I agree and will go further to say a 360 sounds like crap. When my car was injected, when starting up it did sound like old plumbing I'll give you. I even think tubis sound a bit tinny. After actually using many different exhaust combos, the sound of the flat crank V-8 with Webers and a proper flow-through exhaust with resonators is what the car was missing.

Not the best recording, but here is my car with Webers/Flow through exhaust. Would suggest headsets.

Russ, Call me stupid but I can't get your video to play. I know I promised to send you a video/sound clip of the same on my car, and I will, but I've been struggling with other issues with my car and didn't get to it yet, sorry.

A tubi on a 308 is at least a big improvement which isn't always the case. We've removed tubi systems from two 550 Maranellos due to the horrible sound quality and reinstalled the factory parts.

 

Hmmm - It worked last night and now as well. Will try to reload today in a different format.

It takes Quicktime, it takes a moment to load.

PM me an email address and I will send the 2 Meg file.

 

Well, a proper V-12 is doable in a 308. Its been done several times. I thought that guy in Atlanta, Atlantaman? someone was building one down there. Then you could have four individual exhausts out the back.

But I do like the sounds carbs make. Wil, have you heard a 308 with a gutted airbox? It really makes a big difference. I know some have commented on a VW chirping sound from the exhaust, but I hear nothing like that with my Ansa. Heck, I barely hear the exhaust over the carbs if I have the windows down. I can imagine a blower on a 308 having a new sound all its own.

 

Sounds like you are going full tilt Mark with this project. Way to go!

I have a complete spare engine & transmission apart in my den that is awaiting the final conclusion on QV head work? It sure would be nice to make 400 rwhp at 10psi or less. I do not know how the transaxle will respond to 500+ rwhp? It is a kick in the ass now.

A traction controlled 700hp 308 would be insane! You have me intrigued for sure.

Both Bob Norwood and James Patterson suggested that I go with the Motec setup a few years back when they put my new engine together. I could not justify the expense at that time since I had just replaced the Haltech with their latest ECU the E-6K. Looks like the Motec will be the way to go with the next engine. The M800 is a trick unit compared to the Haltech. Looks to be much more capable of a unit. I am anxious to here your opinion of it.

Yeah, I know the conversion has been done. What I meant was they should have built it that way to begin with!

Ever wonder how well an F1 V10 would fit? They look pretty small and they do scream nicely.

Anyway sorry for taking this thread off course.

 

Sounds exciting Mark but isn't that patio block money you're spending on that Motec? Being able to tune individual cylinders is a nice capability. It's funny though since the original 308 had that capability only with a little less power.
