FrankenFerrari - V12 Ferrari 308

In reply to crankwalk (Forum Supporter) :

Last time I had it aligned at a local shop they used the shims they had on hand and got it to factory spec with no issues.  I've lowered is a bit more since then but with it not really running/driving and me planning a suspension rebuild I've not attempted aligning it at the current ride height. 

This time I'm also planning to add more camber and the problem there I'm told is the bolts holding the lower forks aren't long enough so I'm planning to deal with while I'm at it this winter

I've got plenty of camber before the alignment but I think that's a function of it being way way low. It handles great but I have more negative camber dirvier's side thatn passenger and  I'm hoping to have enough adjustment either way. Those Ricambi shims are a lot of money for washers with slits cut in them.

Now I'm really wondering how low is "way way low"?????  

followed by how was it achieved setup wise?

Id 1k seem really big for this.  says the guy with 12 1480s on a 6cyl

The goal was to only be spraying fuel into a moving air stream so the fuel vaporization cools the air not the port walls and that means short duty cycle and that means big injectors.  Originally the plane was to use the show injectors the ducati 999 came with but I got talked out of it and into this plan thinking the ID injectors are well enough matched that it should work out fine.....it still might.  They shipped today so now I wait.

So the tires did not go as planned.  The discount tire place told me they no longer mount used tires, too dangerous.  I stopped by a small place I drive past and he tried, he got 1 but they are just too wide for his machine.  But 1 is enough for a test fit....

Clearly I was just being a big scaredy-cat and 315s would probably fit.....but they really want a wider wheel......what the?!  the wheel company now has 10.5, 1,11.5 wide blanks....hmmmmmmm....anyone want a set of 18x8, 18x10 wheels?

(the forum software has started doing some weird stuff to the pics.....the look right everywhere but here, sideways, upside down...yuck)

In reply to mke :

Regarding injection timing... this is definitely something to play with for sure.  One of my tuner friends found something crazy like 50hp in an LT1 (the 90s Camaro engine) with injection timing.  He also let on that there was benefit to timing the injection so that it acted like an "air door" to prevent reversion, but I suspect that this is also highly dependent on port geometry and injector placement.  An injector that sprays perpendicular to airflow will actually be impeding it.

In reply to Pete. (l33t FS) :

I heard similar things, like 3-5% with sub 38% duty cycle and correct timing.  That's what convinced me to try it.  Maybe someday I'll make it to 5he duno and find out.

Eh I have always had the best luck on close injector position by spraying on closed valves and closed for a hair. They are nice and hot and the initial reverse pressure wave from closing is passed. I have seen power swing in just a few degrees around valve close event. The further you move the injector back the less it matters. 

In reply to Paul_VR6 (Forum Supporter) :

I've hear that too....kind of case by case.  For idle and low power I am spraying on the closed valve and the dyno will decide what I should do at high power I guess.

In other news here in rural PA the major tire places will no longer mount used tires, it took about 6 tries to find a place with the right equipment willing to do it.  Walmart was still fine doing it but said nothing under 40 profile on their machine.  I'm thinking about popping down to tirerack to grab a pair of fronts tomorrow or maybe next weekend because I believe its finally going to drive in the coming weeks :)

Yea my advice is try stuff on the dyno. Didn't know you were local-ish to me. Most poeple don't pop down to tire rack

Im running the Hiro Performace coilovers and they were maybe 1/3 the cost of the QA1 and Moton setups. I don't know if they have a 308 option though. It rides and handles fantastic but at that level, just eyeballing it I'll need to take camber out. .

The new wheels look great on the 308!

Morgantown PA area,...Im sort of remembering oxford area for you?  The delaware tirerack is like 35 or 40 miles and in person will save me about $50 which is the cost to mount and balance.   It for sure pays on 4 tires, 2 it depends but these are kind of pricey so I guess worth the drive.

A buddy just put those on his 348 (former) challenge car....still waiting on the feedback.  Did you get damping curves with them you can share?  kind of trying to decide where I want to go with mine.

If you like the wheels I can get you a set...I know a guy :)

I don't have the damping curves handy but they are 32 way adjustable that actually works and custom spring rates are free (or at least they were a couple years ago when I ordered them).

Who makes the wheels of you have a link? I like my 348 wheels for this setup but I'm always watching out for 5x108 options.

If you can find the spring and damping info I would love to see it...as I said I"m giving a lot of thought to revalving my shocks and don't want to cross into horrible to drive, but I'm not really sure where that line is exactly.

The wheels are my design that I had manufactured in China.  Mine are 18s, I did a 17in design for another 308 guy.  They have standard forgings and can do any design that fits an available forging pretty cheap, it was around $2k delivered last order I think.
