Supercharged Mondial 8

Well, it's was a great weekend and the drive back was a torture test of epic stds. somehow the nav in my wifes car decided to take us up the 101 instead of cutting over to the 5 so i ended up in walnut creek on a monday afternoon around 5pm. the stop and go traffic was brutal on the cooling system but she held on for awhile then i decided to let her cool off and took a break. found out the rad fan crapped out so that was not helping at all.

once under way the temps held below 195F for water and 200F for oil. i have the timing retarted a bit for now until i can get to the dyno. but a 5hr drive in hot traffic and cruising speeds of 80 were no trouble and ran great.

i'm still in need of a few carbon fiber parts to replace the makeshift intake stuff that i threw together to get to the show. with that done and some gauges hooked up the dyno testing will get under way. for now there is a noticable bump in power, more torque really. i can go up the hill to the house in 5th with no issue where as before 3rd was as far as i could go. 4th would bog and 5th was out of the question.

below 3k the car is pretty much stock in power possibly a hair better but i don't think it's anything too noticable. from 4k it pulls ALOT harder.

i'm excited to get her on the dyno and see whats she's doing.

Nick followed me home on his way to Tahoe, and got some highway footage and pics. when he gets back hopefully he can post them up. the supercharger can barely be heard over the exhaust. the only time you realy hear it is when you shut off the motor. and it's not even the SQ gearing!

for those who were able to stop by nicks booth and check out the car, thanks for coming by it was great talking to you all.

mark, still in the shake down mode. i need a BOV as i ran up 3rd and let off, the funny looking welded transition popped off the CIS. so i for now i drive like grandma and will only run up the gears provided i have no traffic and the distance.

it does add heat to the engine but nothing major. in traffic i'd say around 30*~50* but once moving the temps stayed at the 1/4 mark. and that's without a working rad fan! the oil temps are also slightly higher as the supercharger uses engine oil to lube the gear set. even in the worst of the heat the oil hit about 215, cold really for the redline 10-30 i'm running.

i'm not going to dyno test/tune until i have the carbon parts done. that way i have an accurate base to work from.

 

straight bolt on, the overall plan i decided on was to make a simple bolt on power adder without the need to replace the stock EFI or MFI in this case. the WUR ferrari used for the CIS is the same one the 911 turbo uses, it has the functionality of adjusting for boost/vacuum. hence the $$$$ cost.

now ovecourse you'll need to tee into the oil and drain. and re-route a few lines but nothing major. it suprised me how it came together, i was really expecting some big road blocks. the biggest change will be the dampner and pulley setup but all of it can be returned to stock in an afternoon or weekend depending on how many beers you drink.

i have had the unit itself in and out of the car 6 times one afternoon for various test fittings and mock ups.

 

the gauge is accutually a vacuum gauge attached to the EGR port before the TB plate. i have it there for idle adjustment and ran short of plugs so it stays for now. it'll read boost right about 2k when parked no load, but ofcourse this is not what the plenum is registering. curouis now i'll go read off one of the plenum ports.

the need of the BOV is becouse the CIS uses a 'flapper' door that will slam shut in sync with the TB. as such it'll 'stack' against the charger and run the risk of surging. i've been driving around playing with revs and so far have not encountered another 'POP' although i haven't dropped the revs from 6k eithier.

the pressure build up in the crankcase has been an issue since day 1 long before the FI. and only at 5th gear cruising speeds. i have a morose vented catch can that has a welded in 'crank vent' the 2v motors seem to have an issue with crank case buildup. the motor is a re-build by the PO from t-rutlands and has about 12k on it now. so i can't imagine it just a milage problem.

i'll clear the PM box.

 

thought i'd share a neat find. a before and after pic. i took the before pic when i first got the car. looks like two different engine bays

the air cleaner is tucked into the opening behind the side louvers. it's a K&N cone filter. i had to remove the stock fiberglass duct work to fit it in. the mondial has a very large opening compared to the 308. the mondial also has another vented duct that runs cool air over the headers and firewall to attempt to keep the heat from getting to high. not sure how the 308 manages that.

 

i have dyno time booked for saturday providing i can get some more stuff done in time. i'll be doing alot of runs over a week or two period.

for those interested, here is some renderings of the 3d models i made for testing space and brackets. this was done in acad and done in full scale, i has to plot points off the engine and bay to make sure it all fit. from there it went into the cad program and was built virtually first.

alot of engineering and effort went into making right the first time and look factory as well. hope i managed it. not the best renderings but you get the picture.

thanks guys,
sad day though, no dyno numbers tommorow. freak thing, front shock sheared the rod and i lost the suspension. no damage to the car thankfully but i'll be down until i get new parts and sort why it happened.

i'll get pics as soon as i start the job.

 

well.. currently the engine is sitting waiting to be torn down and 'overbuilt' for another wild idea. The engine ran great for 30k miles on boost and then I wanted more, been busy with other builds and projects so it's always one step out. otherwise nary a problem, not to shabby with CIS as the fuel management, EFI would be leaps and bounds above it though.

The current blowers I use for the builds are Rotrex head units, I liken them to belt driven turbos. Rotrex recently just redesigned the impeller and picked up 20% across the map. looking forward to testing the new design in the next month or two.
