Just a quick update, the coils are not done being wound on the dyno yet so no numbers...I continue to tune on the street a bit. Working like a dog so not too much new stuff.

I just installed the last of the secret cooling mods. Carlos is a f*cking genius! This car varies by only a few degrees, getting up to maybe 84 celcius before coming back down to 80 to 82. This is in 93 degree ambient temps, high humidity (subtropical Florida), FMIC, a/c on FULL BLAST and in traffic. I actually TRIED to get the temps up a bit by flooring it every opportunity I had on the way home today. Nada. Temps didn't budge. And I wanted to go V-mount why???? Oooh...the new Mobil 1 15W50 seems to be holding its viscosity very well. Pressure is remaining constant whereas the old stuff thinned out quickly.

Tooling around at .9kg at the moment with the odd uncontrolled spike on the AVC-R going up to 1.25kg. Full on rich up in that region and the car has never registered anything over 35 on the PFC's knock gauge (and that's at super lean cruise, not WOT).

My only complaint is the Power FC not relinquishing full control of the idle parameters...still idling in the 11.5:1 range and my B10EGV's are probably giving up the ghost after a bit more than a 1000 miles. Thank god for Autozone's 1yr. warranty!

Just purchased a set of Aragosta coil-overs so I'll hopefully have those on soon along with the RE-Amemiya induction light pods. I'm really enjoying the car for the first time since I went with a single turbo Once the widebody, new rims and the new interior go in, I may actually be done. Amazing. I'm going to have to take on a new hobby to keep myself occupied, LOL.

 

Just a tid bit 84 is a bit on the cold side. You will make your best power around 97 98 degrees, not doubting Carlos but I bet he will agree on those numbers However just being able to stay stable at 84 is nice. I would try and shoot for a stable 88 degrees, wouldn't be too cold or too hot. Drive on up here our Dyno is up and running!!!

 

Michel, we'll have to see if your super secret cooling mods can out-do my get-cold-air-to-everything-and-run-cooler v-mount setup. I've tried beeping you a few times, but no luck, i was wondering how this was coming along... give me a call sometime.

harrison

PS.... though working on the car is really easy without it.... i want AC....

 

Yeah, been busy with work...I'm actually in Miami for a bit doing a story on obesity at the Cleveland Clinic. I'll try and buzz you on Sunday/Monday Harrison. Want to come over and help put the Aragosta shocks on ????

I'll have to talk to Carlos about the low temps....I think on the track coolant temps would be a bit higher as it's pretty darn hard to duplicate road race conditions on the street I'd be out there at full throttle for 30 minute sessions. Temps are low, 79 or so when the sun isn't out. Oil temps seem to be lower as well but they're regulated by the Mocal thermostat. Need to add an oil temp gauge sometime soon. I could simply have the fans come on at a higher temp. Right now they're at 81. I need to add a GT40R kit to the mix as well! Honestly, the 4088 plain bearing seems to be a pretty good turbo and it should have some good top end but I'm willing to bet your manifold design is better than what I currently run. Plus the R is water cooled.

As far as the v-mount vs. front mount, Carlos doesn't really like the v-mount setups due to the radiator placement. He's pretty conservative (I know you're reading!) so I may have to try and convince him. I do remember Harrison's AIT's being lower than mine. Could be the AIT thermostat, could be the v-mount and AD9 hood vs. my front mount and Knight Sports hood. It might be easier to run cold air to the turbo inlet using a V-mount setup. Once I get the RE-A induction lights in, I'll figure something out.

One other item I've been contemplating is an inline fuel cooler. I've read about quite a few exotics (Novitec 360) which gained 15hp just installing a fuel cooler. Might be hype, but with the extreme under hood temps, it might be a worthwhile area to look into.

 

Well You dragged me in !

As to the fuel cooler, they DO work. my GT1 20b Race car gained major time on the track while runing a leaner mix., as to how much power, can't say but how about 1.7 secs. at Homestead, and a 7% reduction on mixture strenght. Based on EGT
@ 9600 Rpm 5th gear WOT 1720 *F on Ceramic seals.

As to the "V" mount ?? don't see the benefit. speciallty if You'r after lower engine temps.
As to the AIT, Thought theoreticaly better, in actual practice, not an issue, due to Your CR.
The best improvement possible, a "Large" SEARS KENMORE REFRIGIRATOR in front of Your car, as an IC. !!

 

Hey when ever your ready on the manifold I will set you up with something nice. Me and Carlos will have to agree to disagree on the V-mount stuff though I use fuel coolers and they work well. I have them setup on the boosted GTS and S2K as well. Definately worth looking into.

 

LOL, saving the Kenmore for the new house :-) I do know someone on the Datalogit list had been experimenting with using the a/c system to cool the intake charge for short bursts. More work than I want to tackle currently.

 

cool, thats what the new... or old, lightning did... gave quite a boost for 20 or so seconds.....
the radiator on my vmount setup sits almost just like stock, but backwards.... i dont' know what there is to dislike about the placement. the heat from the fans blows down under the motor as well, and not up onto the intake manny and intercooler etc...

 

Well had a bit of really bad luck today. I've had lots of people waiting for numbers (me too!) and they'll have to wait a bit longer. Besides the dyno not being down, I managed to grenade a LARGE rock off of a gravel truck on my undercarriage. The end result was a punctured oil pan (Xcessive Motorsports cast pan, yeah that expensive one!) and the loss of 6+ quarts of oil in about 50 feet. Luckily I saw it coming out the back and saw the gauge pressure drop to zero. I shut her down immediately and had it towed back to a local shop. Unfrigginbelieveable. Xcessive is currently OUT of the oil pan so it'll be at least two to four weeks before she's back up and running. Guess it's time to update the body while I'm waiting, sigh...

Harrison, sorry I missed you again. You always call me when I'm at work :-)
Michel

 

holy crap.... i hate stupid dump trucks.... that must have been a HUGE rock!

harrison

 

I may have a pan for ya, I will check.

 

Awesome! Thanks Sean. Sent you an e-mail last night too as I figured you may have one.

 

One thing I don't like about the $500 oil pan besides it not coming with an oil level sender mount is how low it sits in the sub-frame. Should have just dry sumped the bitch!

 

cast pan, dont like the sound of that.
matt

 

It barely sticks out, and is easliy protected for those who feel a need. But Dry sump is oh so nice.

 

It may sit a hair lower in my application due to the Cosmo engine and custom motor mount. I do think I'll find a way to protect it. I should have a pic of the pan here in a day or so. Just very busy at work currently.
Michel

 

Michel please call so we can get this pan out to you. Also I have a way for you to protect the pan.

 

Calling now! (left message w/cell number Sean). Thanks for tracking one down! You guys ROCK.

Don't have a pic of the damaged oil pan yet but the shop said that the rock hit the leading edge and ripped a huge chunk, almost all the way to the back, out of the oil pan. In other words, welding is out of the question. It also appears that the rock may have dented the radiator (which is fairly new) and a few other secret items. I'll probably have to replace the oil pickup but not sure yet. Damage was on the left side of the pan while the front bumper (lower splitter area) was ripped on the RIGHT side. Physics. RE-A N1 front end will be here in two weeks. I'm hoping there isn't much else I need to replace. It's so ironic I'd just raised the car a bit with the addition of the new coil overs.

 

ON the fuel cooler idea, I have a 1975 Jaguar V-12 , and it had this silly fuel cooler in the A/C system, DUH! I took it out and thru it away , maybe not to smart. RON

 

LOL, yeah probably a bad idea, especially on a mid-70's jag!

A big thanks out to Sean at A-Spec who literally pulled his own brand new cast oil pan off of his extra motor (no oil through it) so I could get back on the road sooner. Whenever I've needed something A-Spec has really really come through.

Do you by any chance have an RE-Amemiya N1 front end just lying around?

 

Wow! Just read through 7 total pages of stuff here...great info!!! It's awesome to know that guys like Carlos exist for those of us who have enough passion to keep these amazing cars running. While I don't live in FL, I might have to fly out there one of these days to check the place out and talk to him personally, and maybe even have him build me one of these beasts and tell me the cooling secret so I can run huge reliable power while sitting in stop and go traffic at 100F+ degrees summer heat here in SoCal. Keep this thread going...I'm curious how it turns out! So sorry about the oil pan incedent but at least you were quick enough to shut it off before you seized the engine. Pics please (after you sort out everything of course)!!!

 

Will do! Just an hour spent with Carlos is like having a rotary epiphany. You think you know it all and then someone comes along that's so far ahead of the game that you have a paradigm shift. Wait til he brings out the 3 rotor FD

 

I feel the same way when Rick talks...I've probably got a ton of places to be, but when the man talks...I listen well, and until he is done talking.

?uestion: If you were to add a fuel cooler, where would you put it?

 

Inline with the fuel lines. "Possibly" set up like you see some of the trans coolers, in the tail. I have the RE-Amemiya rear diffuser Pro so there's a good safe place to put it. There are two types. One looks like a typical transmission cooler, one tube which undulates back and forth with aluminum fins, and the other is an extruded tube with fins. Barry Grant has a new inline type, extruded with radial fins which looks nice. If you go to Summitracing.com, there are a few available there.

Also, their fuel pumps (Sumo line) look very interesting...perhaps one could replace my two Walbros. As an added benefit, it has a built-in fuel filter and dry breaks when you pull it apart to clean the filter. It also has an internal bypass so no return line needed. I'm not sure how I would integrate my fuel pressure regulator with these pumps...maybe it can be used both ways?
