McGehee/Forza Supercharger Install!!!

Oh come on man! Stop teasing us!!

DETAILS! PICTURES!VIDEOS!


ARGHHH!!

 

OK, OK, here's what we did today in a nutshell:

The remaining parts came in via UPS and FedEx, so there was nothing holding us back.

The oil lines were hooked up, new harmonic balancer and pully were installed with new trigger wheel. XDI-2 sensor was installed in the new bracket everything lined up.

Final fittings, tightenings, and wiggling, and we're ready to start it up!

It started right away, but we noticed a rubbing (pully on a cooling hose) and a slight oil seepage at one of the fittings, so we turned it off. Took care of those two issues reasonably easily, and started it again.

It wasn't idling quite right, so we changed out the advance map on the XDI-2 unit to one that I'd made up to match the 308QV euro advance curves, and that takes advantage of the MAP sensor. We also checked the alignment of the sensor to the trigger wheel at true TDC, and found that needed a slight adjustment. Took care of that easily enough and started it up again.

Idled MUCH smoother. Turned it off again and adjusted the needle valve for the oil flow to the supercharger blower unit... they come pre-oiled so we could run it for a few minutes at idle before putting normal oil flow to it, and that's what Scott adjusted since we don't want the full flow of what the 308 oil pressure is capable of. Got it the way he liked it, and hooked it up to the SC.

Fired it up again, and with oil going through the system, enjoyed rev'ing it up. It sounds a little odd at idle compared to stock (a bit "raspy" or metallic) but once you're off of idle, it's just SWEET.

Then I took it for a test drive with Scott in the passenger seat. That "throw you back in the seat" between between 1st and 2nd gear put that HUGE HUGE smile on my face that could be seen a half-block away. One fitting clamp came slightly loose so not all the blower air was going where it was supposed to, but it was no problem to make it back to the shop for a quick tightening.

Took several aggressive runs up and down the street once the temperature was up. No issues, just FUN FUN FUN.

Couldn't get in to the dyno today (they had other appointments) but we're on the schedule for 10am tomorrow.

Pictures coming!

 

I've got video from some runs today, more tommorow at the dyno. whish I had video of Mikes' first 1~2 shift thou the grin hit his face a mile wide and will probably be there for the next month or so. he's already itching to up the boost.

and you'll have to wait for uploading as I'll be editing it when I get back home.

For now, I'm enjoying the southern weather and the Bar-B-Q!!! ummmmmmmmmm.

 

i hate you both!





lets see some video!!!!!!!!!!!!! PULEEEZZZZEEEE?!

 

Yea!!!!

 

Here's some pictures of the completed assembly just before we put the clamps on for final static test before it went on the road. Keep in mind that the piece that fits after the blower and attaches to the CIS intake and has the blow-off valve attached is temporary... a new custom piece is being made in carbon-kevlar and won't require the step-down hose. The black elbow arrangement feeding the blower is really just fine as is, but Scott is having a carbon-kevlar piece made for that too. They just weren't done on time by the c-k guy, but he wasn't going to let that keep us from doing the install.

I already knew that Scott was technically astute from some of his other custom 308 projects, such as the adjustable cam pullies that he made for himself and that many of us got in a group buy. But until you see this setup in person, you just can't fully appreciate the attention to detail in the design and execution of the "system"... if you didn't know what a 308 QV engine bay was supposed to look like, you could easily presume that these are all factory components that were designed as part of the original. I kept thinking to myself, and occasionally muttering out loud, "Wow" ... really. I'll take more pictures tomorrow now that it's all back together, and also post the dyno results.

I offer to host videos, photos, etc.

 

Chris, that's the BOV, or blowoff valve. in the carbon finished part it will reside under the intake so it won't be visable.

 

It's my 1984 USA 308QV, about 60,000 miles (40,000 miles of which are ALL MINE!)

 

The stock cam covers fit fine with this SC setup on the 308QV and 328, but won't on the 2V cars since the covers are bigger there.

 

Mike, Scott i just got to say great work. Thank you.

 

Ok, now i got that outa the way. Here come the questions.

Man, that looks tight. Or does it look tight from that angle?

How much room is there?

it clears, the pulley tapers back so from that angle it looks like they are together. it's close but no hitting, new hoses would freshen it up though

 

..yep..a good example of how Scott does things. I have seen some of his other projects in person..and ALL have been done pretty damn thoroughly! The quality of his workmanship and choice of materials is second to none!

 

Mike,

You should really get Scott to "autograph" the installation..before he becomes a legend..


"..never ask a Scotsman about what he wears under his kilt.." ;-)

 

Guys, how do you rate the install?

Can a Pizza guy, like yours truly, handle it? I'm concerned about cutting the wrong oil hoses.

Hey, oil, water, air hoses they all look the same to me.

 

You bet! Or if you're up here before then, let's get together.

I no longer covet Branko's euro QV...

I've had my license plate for several years, but I have to say that it is now more appropriate than ever!

Wow , I'm so excited at reading this , i followed the other thread for a while , pardon me as I haven't read this all properley , but is this kit going to be available for us in the Uk , can it be fitted to a euro spec 308 qv and is it the sought of thing that the garage that sevices mine could fit.
Oh and how much is it likely to cost,
Cheers
Dave

 

Hear that all you 308 fans out there? How lucky am I that Mike lives just 100+ miles from me?

 

Good luck! We're all cheering you on!

 

Are you bringing this monster to Talladega?

 

At the dyno today...

More photos of the completed setup...

You can see why I think it looks "natural" like it might be a factory add-on... and I like that.

Is he off or near 95??

If he is, i'll have to swing by his place when i'm heading to Florida.

Would love to get a ride.

 

Looks great! I can't quite see if the A/C compressor is still in there - looks like it is? Looking forward to the dyno numbers and your final impressions!
