Also, I am doing something, something not a single person has done, and that's working on tuning the denso ECU, here soon I'll be doing a hex dump of what's inside the eprom. That'll be valuable to hopefully someone someday. Thank goodness you're a veteran member, hopefully you'll be around for the next year to watch progress.

 

I’ll look forward to it. I believe that will be a great help to many with that system to have it demistified.

Jaguar was one of the pioneers of Fuel injection and we as a society had to learn a great deal. Starting from 3 VW rabbit systems to the finial Ford updated system massive progress has been made.

in the 1980’s90’s and into the 2000’s cars ( all brands) burning because of fuel injection was very common. Less so recently as knowledge was gained.

 

Only if a few simple basic rules weren’t followed.

 

You made my point. You're not Brian Lister so you're not getting there. You're not a do'er you're a "read poster" There's a big difference and you dont even fully understand what you read. If you think a Lister engine is stock inside you're day dreaming again. I'm done here, lots to do in the garage. I'd love to settle this on the track. Which I've done, won a few, lost a few. But I always showed up. I could always tell who wasn't going to show up and you're one of those guys. 100% no-show and excuses. You can levy the final insult.

 

Sorry if I insulted you, I would like you to explain how his factory HE castings are different. If you can, then your point of the HE heads not allowing for boost may be valid. What's known about that motor, is it may have mild cams and a touch of port work. Other than that, airflow through that motor is not much more over a stock 6 liter. So, what do you know? And btw, I've been wrenching for 9 years, not long, haven't done anything revolutionary like what I'm trying to do here. Yeah, I want you to expand on what you said at the end. So far, your negativity has zero depth. I support negativity and skepticism, if it has structure and knowledge behind it, but without structure and knowledge, it's called cynicism. And cynicism does nothing but subtract and take away, it does no one any good what so ever. Please, school me, drop the knowledge bomb. So, anything else regarding the he cylinder head and accepting boost?

Adding on, it would be safe to say, the Lister motor made somewhere in the neighborhood of 370hp-410hp by itself, going off of the rule that 15psi doubles the hp of a motor if it has 9:1 compression, roughly.

 

ivan is that a 6 cylinder engine?

 

Is what a 6 cylinder?

 

Lanky right? Visited him at his house back in the 2000's before he sadly passed away. He had an XJR-# in his garage(s) that was being worked on. Nice guy. He talked a little about having the custom heads sent out to air-flow research for porting and issues they had with the head gaskets that they tried to fix with cooper rings (gas filled silver plated things). At that time he was even into lawn-mower modification and racing.

Well, I thought a ms3 was $2500. Found out the real price. Going to leave the stock ECU where it's at, and have the ms3 just for spark, fuel, and wastegate. Now the question is, can I intercept the sensor signals for the ms3 or will I have to leave stock sensors in and have the ms3 have it's own? A ms3 is $700. Also, ran the **** outa the Jag and knock hasn't changed.

 

Ron, I know good coatings work. I’m familiar with Swain, most serious racers are. But reading between the lines here a lot of people on these sites have never Had a piston in their hands or spent much time assembling an engine.
Heck there is one guy who tells people it will cost $20,000 to rebuild a V12.
You had the experience of selling off 3 V12’s for scrap metal prices because you couldn’t find a buyer for them. I had to scrap 35.
Yes I regret it. But like you, there aren’t that many buyers for complete engines. There are web sites like Car-Parts dotcom that list various parts with prices and mileage some with warrantees yet some people keep lumping Jaguars.
If they simply want more power the Jaguar V8 makes up to 510 horsepower and it’s considered an upgrade rather than lumping.

 

Ivan the car in the picture you posted?

 

It's a v12. Sometimes it's a 6 cylinder when B bank shuts off due to faulty map sensor, it might be a 11 cylinder if I throw a rod.

 

Have you seen this, Bradley Smith's twin supercharged XJS

Boosting a HE can be done 20psi maybe pushing it, the V12 has a tendency to lift heads even with no boost as the head studs are very long.

 

i agree warrjon, open deck blocks do not lend the design to hi boost pressures! ( not sayin some have used them anyway).
closed deck can use short strong studs, seems to be accepted designs!

 

Those top fuel engines all tend to have long studs deep into aluminum blocks. On the other hand they don’t use any coolant so there are no water passageways either.
If lack of decking is a real weakness it wouldn’t be that difficult to take a flat plate of aluminum and machine it to fit. I suspect you could actually save weight if instead of the real thick iron sleeves each cylinder has, a person used regular stepped sleeves.
Not saying it would hold up to 9000 horsepower but maybe a little stronger than the open deck. I’m sure Jaguar tested both methods to see and it would be interesting to look at the actual numbers they arrived at.
Seems like there is a lot of eyeball engineering going on without facts or documentation.
My own gut feeling is I’d like to look at the top deck of the 4 liter AJ6*engine see if that too is an open deck.
Considering that engine was pretty much designed from the V12 and long enough after the V12 was made it would give us some indication of if the factory felt the top deck was needed in hindsight.

That had 240*Horsepower from 4 liters compared to 299*. horsepower in theV12.
* euro spec DIN horsepower

 

Well, I'd like to just run pump, and maybe do a 100 octane setting, that'd only be 22 psi. As far as heads lifting, ARP? If the open deck becomes an issue, devcon will save us. Also, Honda guys go HAAM on aluminum open deck blocks.

 

intercoolers do cool the charge air but not as much as using alcohol or alcohol and water. The advantage of alcohol over intercoolers is every time you change direction or flow you lost boost. Forcing you to use a bigger and bigger turbo which increases heat and lag.

To prove my statement to yourself poor a little rubbing alcohol in one hand and a little gasoline in another at the same time.
What will really cool down a charge is if you supplement that with a little windshield washer fluid
If you want to halt Preignition completely while increasing boost do as drag racers have been doing for a long time. Trigger WWfluid at high boost with a knock sensor.

 

Holy crap I barely understand myself in that quote lol. I'll run a knock sensor and not go too hard on lower octane. Probably only go to 18 psi on 92.

 

Just how much do you intend to retard the timing to keep the engine from destroying itself? Considering the HE runs pretty retarded to start with and you’re planning on boosting it by 15 or 20 pounds?
All that on 92 octane gas?

 

Since it does not have knock sensors to enable it to run in the edge like a vehicle with a knock sensor can, it shouldn't be too much of an issue, egt's will be a little warmer than normal, hey maybe that'll help spool lol. But very valid problem, we'll have to see!
