So what is the highest HP in a Marauder?

[Crazieboutamerc]

I am just curious what is the highest horsepower that someone is running in a Marauder?
what mods?
power adder or N/A?

Triple Threat with 4 digit numbers ,There are many others that are up there. :D

:dunno: Over 9,000? :dunno:

He also has a big block chevy motor powering his car.

Maybe a better question, what's the highest HP in a car that you could get in and drive across the U.S.

+1 dont really care too much for a full drag car

On what fuel budget?

Well I'll be heading cross country soon from Virginia to Washington State soon, so as far as I know: mine haha

Just look at the Time Slip as proof.

What's a budget?

[Crazieboutamerc]

I was looking at a Ford powered.

Going by the list not counting the chevy powered abomination, MarauderTJA with 772 HP # 3 on the list. martyo is #2 but no HP listed.

Today I drove my MM to Lewes De. to visit my sister then drove it back to Medford,NJ (home) but iam only making a little over 700 RWHP. Spent last weekend racing at MIR, this car makes me :)

As far as FORD powered or even modified stock type motor go...

Motor re-BUILT to 5.0L fully internally balanced with ceramic coated piston tops & slip skirts. Vortec Air-water inter-cooler system has been heavily upgraded with parts from froozen boost & now see's approx 10 degree increase in temperature on a 95degree day while traveling on highway at 70MPH. The blowoff valve is now used as a Bypass valve & is piped from post intercooler to the inlet of the vortec. This eliminates most if not all spool up lag or loss of boost during shifts... Thus the power the motor makes; start's down lower & is smoother throughout the RPM range...

My Marauder was last dyno'd at 623rwHP & just shy of 600rwTQ w/ 21.7PSI at max. It was still increasing with rpm beyond 6800rpm dyno tune run max was reached. Motor built to withstand extra rpm over stock... Fuel was getting a lil lean above 6500rpm.

The supercharger has now been upgraded to a JT-trim from a T-trim vortec that was used during the last dyno tune run. This is all running 93 OCTANE & 23MPG on highway has been seen.

Along with vortec upgrade, 2 Ford GT supercar fuel pump(s) & all new -AN oversized fuel lines SS fuel lines run directly from each pump. Separate fuel lines run from inside the tank & merge just before Kinsler fuel filter & then continue to the CPR fuel rail(s).
Also each fuel pump has its own mod'd FPDM & all wiring has been oversized & is ran seperately to each pump from its own FPDM. The battery (in trunk) has oversized wire(s) directly powering the FPDM's.

I have been told the upgrade of the Vortec supercharger alone should have a gain of 50RWHP minimium. Now that the fuel system has also been heavily modified per above I expect another 50 RWHP able to be tuned into the car...

The vehicle needs another Dyno tuning session with John Lund to get the full potential of these latest round of mod's...

I believe once on the Dyno for tuning; the Marauder will lay down #'s north of 700rwHP & 700rwTQ. Thus, approx 800HP & 800TQ will be made by the motor at the flywheel. This may not be the highest power #'s found for a MOD motor powered marauder but I do believe these #'s should break into the top 10.

More build info avail upon request... What do others running MOD motors have on the DYNO...?

[sailsmen]

How have you made out at the track with that bad boy ?

[LANDY]

I blew the rear main seal at 849rwhp with a catch can set up, ran 10.55 at 701rwhp and litterally drove it everywhere ;)

[Loco1234]

How have you made out at the track with that bad boy ?

We dont really go to the Drags with it... or atleast haven't been... would like to try some day.

We have & do take it to Pocono international raceway during 2 holidays weekends in the summer. A few car enthusiast's club rent out the track. We run 2/3rd's of the high speed banked tri-oval. However, instead of running bank corner 3 we do a flat 160 degree turn in an infield potion of track then runs thru a few twisty's & then back out onto the front straight...

Many well rounded perfomance mod's have been to to match the handling & braking to the driveline perfomance...

However, I must say the best "for track" mod done somewhat recently has been the 31spline Detroit True-Trac rear (stock ratio). The car lets your feel like it just wants to grip more & more accelerating out of a corner...

[Loco1234]

so it's a 4.6L motor stroked to 5.4L...? I thought the max was 5.3L & it became wet block...

[martyo]

Just out of curiosity, how many of these high hp applications found it necessary to run something other than the stock COPs? And by necessary, I mean that the stock COPs were failing under the load?

I may not qualify for high horse power but I melted a MSD coil. Not sure how or why it happened.

[Cheeseheadbob]

Marty, I don't know if my car at 459 RWHP was considered "high HP" but I was running the stock COP's and never had a problem. Except when I power washed the engine bay and ruined a couple. :mad2:

That $1.75 for the wash turned into $800 real quick... :rolleyes:

[jsignorelli]

The dyno data was for the engine on the test stand, so they are fly-wheel values. Rear wheel is usually about 80% of the fly wheel numbers.

As for the block holding together, I have only run the car on road courses at the SAAC weekends, when I run my Mustangs and Factory Five kit car. No crazy needle burning acceleration or drag racing. I just get to high speed and keep it on the track. The Ford Motorsport heads have larger combustion chambers than the stock heads, and the stroker kit allows a 5.4 - 5.6 displacement with no real problems.

I forgot to list the Sparta Performance suspension (control arms, F & R anti-sway bars, and HD shocks).

Every time I clean the engine I use "shower" nozzle setting, cover the COP cover and 1/2 the time water gets in the SP Well. I always remove the COP cover and check for water.

I had a bad experience many years ago from pressure washing an engine. Pressure washers are great for concrete.

Mine required a switch to stock GM LS truck coils, but that's because I have a BigStuff3.

[TooManyFords]

And you just keep on smiling John, OK?

I always am!

[Blown3.8]

everything I've built is running stock coils 6-700 hp gaps are .025-.032 BR7EF plugs.

That doesn't count so go back to feeding your cats!

That si my point!

[LANDY]

Stock coils Br7ef at .024 gap. people are running over 1k hp with stock stuff.

[hotford]

Yup I ran the same plugs in my mod fox, gap was .22, never missed a beat even when the shifts were at 7400 and running through at 7800 rpm,!!

Must 1st tuning session with John Lund I had Graniteli COPs in car... He asked me to remove the & re-install the stock COPs & I run them now all the time & every dyno tuning session since...

Have not hit a problem with them yet..

What kind of power are you making to be running BS3?

Cool stuff.

[Loco1234]

Although I utilize the stock COPs; I have also upgraded to a solid adjustable length connector for thee COP to the Plug. Info from a website about product...

"Instead of having to use the weak and prone to fail factory spring-type connector, factory coil packs can be upgraded to use a connector that can be adjusted for it's length. This can be accomplished on EITHER end of the connector to compensate for spark plugs of any different length - like the Denso Iridium spark plugs and many other aftermarket performance spark plugs that tend to be a little bit longer than the stock spark plugs on these 4V modular engines - this is an important feature making it simple to deal with during installation and giving you a secure connection that does not depend on a spring stretching or compressing like the factory coil pack connectors."

[blkZooM]

This could have been done already excuse me if it has been, but can someone start a thread where we (meaning people who's actually had there car on a dyno) post up rwhp and torque, their mods, fuel and kind of dyno they were on

[Limited360]

LJI372's Silver car is 641whp on pump and 791whp on C16+spray.... maybe he can correct me on these numbers if they are off by an amount, but I think the ballpark is right.

Could drive the car anywhere now that it has quiet mufflers!

[sailsmen]

Would be great to see some 1/4 times to go with the Horse Power.

[BlackHole]

Would be great to see some 1/4 times to go with the Horse Power.

428 RWHP and went 12.96 at 108.9 MPH at Norwalk on June 14th NMRA True Street test run. Think the temp was 68 F
