the James bond label makes it so much better

 

Haha bond james bond .im really looking forward too this build these cars get more rare every day and soon will be sought after in my opinion(bias) but I'm going too get it set straight then it'll be built up performance wise going for a t56 in it id like too go bigger on thd brakes if brembro makes them . Have a few ideas for air scoups that push as ir from fender too the brakes. .. Too much thinking the fire departments callin! Haha i want the lister body kit for it big time any idea where too aquire one? Thanks guys

 

so ive been doing a bit of research on the mega squirt only has one feed for a maf sensor... soo what are the opinions on making my own intake ? im a fabricator and a skilled welder ive the resources at my finger tips... thoughts on this ??

 

Why do you want go MAF, these are a restriction to intake flow. Any performance upgrade here in Aus for an LSX remove the MAF and use a MAP. May be a bit more work tuning it but better in the long run.

Going a single inlet for V12 will require removal of the distributor and AC compressor. If you are set on MAF, I would use 1 on each intake and either connect them together and average the output or just use one as the input to the ECU, this way both banks will get the same volume of air.

 

Well ive been reaserching for a bit and ive been looking at the ms3x I just can't find any info on it. Im looking for an input for knock and a baro sensor as well I figure this would be useful running 30lbs of boost .knock is a definit need .

 

88 you gotta be kidding, 30 lbs boost into a jag V12, you may have to go to the moon to pickup the blown up pieces!!! LOL,LOL

OK maybe just the next county! thats where the knock sensor could be, YIKES!

 

Ron is right, I know a guy here in Aus his XJS twin turbo runs about 10psi and makes 600RWHP and is a full race preped engine $$$$$$$$$$$$$$$.

The MS3 has quite a few configurable inputs that can be used for knock etc. The information is on the MS website there is a link from DIY Autotune in the complete ECU section under MS3.

As for KNOCK sensors the V12 never had one so setting one up is going to require many of hours of Dyno testing to have it useful. You CAN NOT just install any knock sensor, it MUST be tuned for the knock frequency of the Jaguar V12. Knock frequency changes with different engines and is directly related to BORE and NUMBER of CYLINDERS, so if you can find a V12 with 90mm bore then use this knock sensor you will still need to experiment with placement, as this is very important. Otherwise all the knock sensor will do is retard the ignition with other engine noises.

 

Okay 30 may be a bit extravagent haha but you get the idea i'm shooting for 800hp both the turbos going on are capable of 1000 a piece so it shouldnt be hard.i'm pretty sure it can handle it. I'll be putting in connecting rods dished pistons and completely revamping the heads/timing chain and cams.

As for the crank I've been told they do just fine but if I can get my hsnds on a twr crank... game over! Lol

 

Dont need TRW crank, stock cranks for all 5.3 and early 6.0 are forged as are the con rods.

600hp at the wheels is around 800 at the engine. Turbos - Bruce is running twin T3 off our Aussie 3.0L nissan I6 Commodore, more than big enough for this level of HP. Be prepared for some major plumbing work and a huge fist full of $$$ if you intend to make this HP for more than a few weeks.

 

Cal:

Strongly advise that you check out Philip's page on dual EDIS on the Jag V12. He pretty much pioneered this for the Jag V12, and this system works really really well. I have driven his '80 XJS, with a 5 speed, and it is as well behaved on cold start and warm running as any new auto as regards the engine smoothness and responsiveness. Responsiveness wise, it is nice and sharp.

On the Tec3 or whatever you are choosing: DO NOT mount ANY timing ring to the damper! This will only give you spark jitter. That timing ring MUST be rigidly mounted to the crank or some part of the pulley system that is mechanically rigidly attached to the crank.

OK 88 when can we expect a running vehicle with your epic engine?

that bradley project could be done in couple afternoons, plus a few dollars!!!!!!!!!$$$$$$

 

Ahh wel thats a good question ronbros rite now i'm gathering info and saving money till I feel ive completd my research on it. July sounds about rite but running may or april waiting for a few toys too sell before i start on this one completely.currently i'm cleaning it up orginizing wires replacing vacum lines basic maintenance inbetween school and down time (which is quite rare).waiting too be released for work again is killing me wallet .

 

Just a few for now I'll try too get more as things go forward

 

Also I will be using rebuilt holset hx52 turbos and eventually id like too put a Richmond 6 speed behind it. Just time and money haha if I had all the parts and a week off I could build it in a week or less but im not someone too rush. Do it right the first time.

 

So I have too ask what makes you say I can't put heavy psi into this motor? I'm curious haha no its not a chevy v8 but its the same principles had a turbo 305 with forged internals on 25/27 lbs it did just fine sold it last year .

 

I would imagine the length of the head.studs would have something to do with that. there is a lot of room for stretch

 

I figured they'd be strong enough. Looks like I'll be replacing those ?

 

88 you see cal has been studying things! thats good!

most Jag v12s failed in race conditions because of head gasket sealing, combustion pressure blows out coolant,engine overheats,not good, you lose!

Jag V12 has and open deck block, to clamp the head on requierd long studs that go down into the lower coolant jacket(not a bad idea), but under hard,long racing the head would lift a little, move around and weaken the gasket seal, and blow coolant!

just say on each lap of a race you lost only 1 table spoon coolant, but what if you got 100 laps more to go, engine will go low on coolant and back to the most dreaded aluminum engine failure,OVERHEAT!!

thru time all types of head sealing has been tried, wire O-rings, multilayer gaskets, cometics, milling stepped recesses in the head for liner protrusion, and a Porsche idea of hi-pressure gas filled metal o-rings, that expand when hot and seal even tighter!

larger studs have been used but engines still failed, all things put together, did make engines last longer, but most failed because of head gaskets!

this info is from B Tullius Grp44,himself, and most of the TWR engines started out with 44 and GM internals, until they had enough money to use F1 race engineered parts,$$$$$$$$.

which engine would you like to have, a $10,000. or a $50,000. engine???

think,real custom performance machine work,to fit GM pieces,, titainium rods, & valves, pistons of ultra design, cams custom made and all the valve train modifications for same!
oiling issues, pumps, oil control internals,, just for chuckles, a custom made billet crankshaft, no chopped up old and stressed factory crank, with a bunch of micro stress cracks that show up when pushed beyond there limits!

and so far we only have a long block assembly, no inlet or outlet manifolds, no fuel system, no electronics or ECU-EMS, no effective cooling system,ETC and other things i cant think of no

porting ,stroking, big bores, and off the shelf cams dont make a Jag do what we are used to in american V8s

but nothing(at least so far) has worked for very long, and this was on N/A engines.

so you want to increase combustion pressures to more than double that of N/A, with,say, 15psi inlet manifold press. 30 will more than triple press.!!

and the slightest hint of detonation will add more heat to the gasket soften it and skyrocket pressures.

if you pull that one off for more than a few runs, we will put you in the record books.

but i digress, if you feel up to it,go for it, you just might surprise us.

my engine has been running for 18yrs now, no problems, but dont drive it like to kill it either.
a lot of this info today was not available then,(NO INTERNET).

Happy motoring!!
