Trilogy project car

[Dennis Reinhart]

Next week along with working on the six speed car we will be swapping out a motor on a Trilogy SC car, while the car is here I will add the IAT in the intake and make the FRPS boost sensitive, and retuning the car I will post complete photos, so this will be a fun project.

 

[BODYMAN]

Work youre Majic Dennis!

 

[Dennis Reinhart]

Will start tomorrow, the owner is here dropped the car off tonight. I will post this project with full pictures and will be posting more pictures of the six speed car.

Well the owner got here last night, the car was here this morning so we got started on it right away, Edwin first took out the transmission and then we took out the windshield wiper assembly and motor, this makes it much easier to get the motor out. When we are done with this the car will not look the same.

Now below is a picture of the stock OEM knock sensor, the 03 has 1 the 04 has 2, this has to be moved to clear the lower half of the intake which contains the SC inner cooler, one of my goals is to see if I can keep it there, so the knock sensor will work as designed and no false knock is picked up when moved to the cylinder head, I will post pictures of this tomorrow. My other goal is to add the IAT in the lower half as done all present kits.

Also I will T off of the back of the intake where there is a boost vacuum sensitive port this will go to the FRPS

I also want to add a larger reservoir this will help the after cooler

Im interested to see how this turns out. What pulley is on this car?

 

[Glenn]

Larger Reservoir ???

Dennis:

What is the part number and year car for the larger reservoir - sounds interesting for Trilogy owners.

Does this one by any chance have black rims and a chrome badgeless grill? I saw a Marauder being hauled into Jax on Sunday when I was leaving.

Glenn let me do the Mod and do the R&D to make sure this works, now lets talk about today, the upper and lower half's of the kit are RTV, together the cobra lower which is used with the SC, and normally the upper is separated by a gasket, but as I said this kit uses RTV, after a year it was very difficult to separate the two, after separation what I found was a large amount of oil in the lower intake, this very well could be from a hurt engine.

Now this oil will be sucked into the intake ports and can cause detonation, again this could be caused by a broke ring, but I want to point this out, if you look at the back of the intake, what takes place is the stock OEM PCV is used on a Marauder is not a two way check valve, since the eaten type blower does not pressurize the upper intake there is no issue of having boost blowing back through the PCV as in a centrifugal blower, that is why I use a EV111 it blows closed under boost, but wit the roots SC the PCV will only see vacuum, but under high engine revs what can happen is you can suck oil out of the passenger side valve cover so tomorrow I am going to install a oil separator.

I will install the separator here keeping oil from being sucked into the intake

Now what we did next is install the IAT in the lower intake, this allows the EEC to see actual IAT entering the the engine, the EEC can correct timing based on actual air temp entering the the engine, since IAT on the inlet of the SC is off by some times over 100 degrees. The IAT is built into the Marauder Maf so that is why a external IAT is added, and placed in the intake where it sees actual IAT entering the engine, and a stock Marauder Maf will peg close to 400 RWHP, so this car will also get a maf upgrade.

More pictures in part 2

Part 2

Now Don at Even flow make a great rear cooling kit, but with this kit it has interference on the passenger side, so I used my rear cooling kit.

Now here is my most difficult correction, with this kit, as I said it uses a 03 Cobra lower inner cooler intake, the 03 Cobra is a cast block, and the 03 Cobra does not use knock sensors, the 03 Marauder or Mach 1 uses one, the 04 marauder uses 2, but they are aluminum blocks specifically designed for knock sensors located in the valley of the intake, since the kit uses a 03 Cobra intake, it will not clear the Bose's made into the block so they have to be ground down. and the knock sensor relocated to the back of the cylinder head making it basically useless, since it will pick up cam shaft and valve train noise giving a false spark knock.

Here is the stock knock sensor location

Here is a picture of the boss that has to be ground down to clear the lower intake, and the knock sensor has to be removed.

The knock sensor is then relocated tp the back of the cylinder head, this basicly renders the knock sensors useless it is not very clear I will post a better picture tomorrow.

So what I did today is take red grease dab it on the stock knock sensor boss then install the cobra lower intake, and see where interference is, as shown below.

What I plan to do is take this intake, drill a hole where the knock sensor interference is enclose that with a sort of aluminum cup, and keep the knock sensor where it's at and it should work as designed. More to follow. I will do this on a 03 Marauder motor I am installing in my wifes 98 Mark 8 with a Cora Eaton blower, I would have tried this on this car car but the owner has to be on the road by Friday.:beer:

Yes this is the one.

Impressive work Dennis but the above statement is not true!!:shake:

Though you probably don't want oil being sucked into the intake it will in fact cause a perceived increase in octane if mixed with fuel since oil molecules are much longer than fuel molecules thus burning much slower, effectively increasing apparent octane!!:beer:

Good luck with all of the mods....I look forward to the finished product pix and numbers!!

Now Jack you have, and I respect your opinion. I have mine, and you are saying oil pooling in the bottom of the take, that will be sucked into the engine cylinders can not cause issues. I will gracefully say ok with my fingers crossed behind my back, I simply say your wrong, but we can have differences of opinion

 

[BODYMAN]

Nice work Dennis! Boy that motor compartment was dirty.

 

[Marauderjack]

I agree to disagree!!:beer:

Carry on....Dennis!!

 

[Master]

I'd always found in the past (and I have a lot of experience with old beaters prior to getting a real job) that oil entrainment would lead to carboning of internals and rapid fouling of plugs. I don't recall detonation issues, though. However, considering the cars I used to drive, I doubt we were ever on the ragged edge of the detonation curve!
Great write-ups, though. I'm really enjoying this. The things that happen at your shop would simply never be done here at a speed shop in Nova Scotia. Maybe at Armstrong's (one of North America's top 10 builders, so I've been told), but not in your average speed shop.

 

[Marauderjack]

I run a small amount of oil in my fuel all the time in ALL vehicles as an upper cylinder lubricant....advised to do this many years ago by an older "Oil Guy"!!:bows:

I have never had a fouled plug or clogged cat and only use about an ounce (Ashless TCW-3) to 2 gallons of fuel........currently at 192,006 miles on the Marauder and it has never used any oil or spark knocked!!:shake:

Sorry to de-rail your thread Dennis.....I'll shut up now!!

My experiences with burning oil are that it will cause two problems: First is plug fouling which leads to missing. Not too nice. The Second is carbon buildup in the cylinders on top of the pistons, on the valves, and on the combustion chambers. This leads to detonation. May take awhile, but eventually it will cause detonation. I'm not sure what the immediate effect would be, but I assume there is less energy capacity in the oil vapors than there is in plain old air and gasoline mixture even if there is a higher effective octane rating. So possibly less power capacity.

192,006 miles? .... How many miles on the Procharger?

 

[O's Fan Rich]

When I pull my upper end off in a short while, I'll take pictures to compare.
It'll be interesting to see the difference a seperator and meth injection make with that crudy oil buildup.
Even NA cars have seen that stuff in the intake.... unless they run 12's then all bets are off!

 

[Stranger in the Black Sedan]

2 stroke in a modern engine. An ounce per two gallons is a LOT of oil. I have heard everything now. Nice.
