FrankenFerrari - V12 Ferrari 308

In reply to mke : 6k rpm...

I worked pretty hard all evening...on air duct still.  The one is cleaned up and about ready to paint.  The second really needed a lot of reshaping.  Once I got the clearance I wanted the shape just looked wrong so I worked until it mostly looked right and re-glassed it.  Tomorrow will be finish up and paint them then the MAP and I think the diode for the speedo sensor came so run is pushed to Thursday I guess.  If it you know...runs, I'm thinking next week I should fit the wheel wells.

It sounds great!  where is the redline on that engine...like 7000-7500 somewhere? 

I think I saw a pic that showed aftermarket coil-overs on that car?  Have you pushed it much to get a sense of ultimate handling?

All well after the storm I hope?

I keep hoping I'll be ready to make a similar video soon......I've also been thinking about if I could install a heads up display and use the car as a driving si8mulator and just start pretending it drives :)

The ducts are finished but what a frikin mess I've got

Tomorrow everything finally goes back together.

That picture gives me the willys, I'm going to go mop something.

Carry on.

you and me both!

I think it's better now, I just didn't like the ducts black.

The deck lid fits....as if there was ever any doubt  :D 

And the tire clearance to the ducts looks pretty good

Ad the multiMAP is repaired as only anon-electronic person could do it...wires everywhere, glue one board to the other then plasti Dip the whole thing

I think I'm about out of excuses not to try starting it again....wait, getting dark   :lol: 

Today it started without ether....not quickly but it started and ran well enough that I had to go into the idle settings and pull a little more timing out than I was using.... then it started running bad, like really bad cylinders coming and going..... and why is the fuel pressure reading 5psi?  Doh! its out of gas.  Its been through 10 gallons since the engine went back in  I think.

Off to the gas station, 5 more gals in, a few tweaks to the start up conditions and it started much quicker, still not right but not horrible.  Back to idle,  free reving said pull some fuel which I did...free reved better.  Took it around the block and it felt pretty good, the new side airfilter has a pronounced sucking sound in my left ear....it reved up smoothly, I pushed it to about 50kPa in first and 65kPa is second so right where the old burnout video was and nothing but grip from the new tires.  5000 rpm in 2nd is just about exactly 50mph just like the math said it should be.  The rear axle sensor was cutting in and out which was unexpected so it should be fine once I add the  zener and pull-down.  From 55 to turn into my neighborhood I did notice the force I needed to use on the brake pedal, they work fine but I need to make getting the higher friction pads a priority.  

Back into the driveway with no weirdness or issues made me think it not only needed a bath it deserved one.  After the wash it restarted, I had to rev it a little (ok, 3kish) to get all the cylinders lit but it started and drove back into the garage so I now the plugs weren't so oiled the wouildn't spark and I didn't notice it smoking at all. I'm calling today a win.

And even cleaned its bay

Bravo!

Awesome!

those wheels are such a subtle mod, man they really look correct. 

Awesome!!!

I like how they turned out too....they are a point of contention in the ferrari community but most everything is I guess as most are concourse not autocross focussed.

Hopefully it will restart today and I can try a longer drive maybe.  I forgot to mention the front antidive seemed to be doing its thing.  I cranked up the rebound adjustment to full as that is the only adjuster I have and these shocks were not valved for the springs I now have, anyway, the car felt a lot better power/brakes  on/off but I can't be sure how much is the antidive and how much is the shocks but the net is good on first impression.  

Also when it was running a couple weeks ago I added a table for cold to warm throttle idle position that seems to be doing its job nicely.  I do have an idle rpm control setup I have not tested....so far I'm just using a simple throttle position set point and as long as it works as it has been I guess I'll stick with it.  I did try to pay attention to where the throttle wants to be during cranking, I have the ability to set that in the ecu so I don't need to touch the pedal, I may try that today but I suspect the way I wrote it it will close too fast, I'll play with it though as a consistent throttle position should make getting the fuel right for good starts easier.  

I just noticed in the log the front brake pres sensor is no longer reading, I need to look ad that and also get the rear axle speed sensor sorted.  Lots to do.

It started again from full cold not horribly.  I made a few more tweaks so hopefully next time is better.  I pushed in 1st to about 6k and 65kPa MAP, then second to 7k and 85-90kPA MAP nothing but acceleration and grip.  It feels amazing and  I'm feeling like its ready for a real drive.....but I need to locate registration and proof of insurance before I go blasting around, after all these attempts I was kind of assuming I wouldn't need it.  I looked a bit but its feeling like I need to get duplicates.  So I'll work on getting it starting better and other at home details for now

Great news! Well, everything besides the paperwork in hiding.

Can't wait for the first proper drive :)

Cold-start is one of those things that make the car so magical; not having to coax it to life and baby it until it's warm.

The challenge is you really only get one crack at it per day.  But I'm pretty sure you will get that ironed out in a jiffy!

Sweet, sweet ride.

I'd be over the moon if I was you. Congratulations. :)

In reply to DaewooOfDeath :

Thanks and it gets a bit better I think.  Looking at the log this morning I realized I have mph, rpm and time so quick math later at 84kPA MAP and 5000rpm it is making at least 296hp, 311ft-lbs at the wheels.  I say at least because the pull was an slight up hill grade that I don't have a good way to account for yet.  Dynomation says at WOT it should be 432hp/454ftlb crank , but if I change the barometer to 84kPa it drops to 366hp/384ft-lbs crank.  Converting to wheel I should expect about 300hp/314ft-lbs...pretty frikin close to what the log says I have so its making pretty near exactly what its supposed to be making, at least its is at 5k rpm...now I just need to get brave enough to try the same thing at 9k 

Edit: at 5krpm, 84kPa MAP is 61% throttle,....big TBs

Edit 2: it was 0.72g.  WOT at 7k peak torque i guess it would be about 1g in 2nd, probably 1.2g limit of traction in 1st....what a difference these tires made

In reply to SkinnyG :

yes.  I built in a few tables to play with but as you say its a challenge....all 3 do similar things during crank so how much from which table is best is a bit of a guessing game. 

This is where I left it yesterday...I think 20C and up the CLT_Fuel_Corr is about right at running rpm but I'm not so sure about at cranking speeds.  Today I'm going to add fuel to the 600rpm column and probably a little to the 700 too in the VE table...right now it cranks at like 180-200rpm, fires then wants to die.  I'm thinking my plan is get get the VE table to where it warm starts good and attack the CLT and start enrich tables to get the cold working and luckily I'm working on cold start just as its getting cold out.

This is totally awesome. You should be so proud that you did all of this!

Here is today's cold start

Then a very short drive......at about 2:40 you will see the new 295 A052s are no match for 1st gear and also that the rev limiter works as it should

Not sure what happened the last post locked up.  Here is the drive video

I cut the burnout into a short for those easily bored
