I can make my 4.2 have 281 cubes

 

Hmm. There are so many ways to dispute this posting I don't know where to start. According to this logic, an engine with a lesser amount of cubic inches (or rather, cylinders) can never ultimately perform on the level of a comparably modified engine with a larger amount of cubic inches. Flawed logic indeed.

Let's look at a KR code 289 cid V8 against say a well built 400 cid V8. The 289 -with little over 1/2 the cubic inches- will kick the living CRAP out of the 400 all day. And giggle doing it. You have to look below the surface of what an engine is to see if it's a 'good' one or not. Rod ratio. Is the engine over-square, square, or under-square (bore being equal to stroke is said to be a 'square' motor). Rod and main journal size. Block design. Cylinder head design and flow potential. Combustion chamber shape and dynamics. Reciprocating mass quantity. Valve size and placement. Camshaft lobe type and design fundamentals. These are all critical factors that make up 'good motors'. The 4.6L V8, for all it's merits, is a model of efficiency and durability. Power will never be it's strong suit simply because of it's design. Does that mean 4.6's can be made to be fast. No. But the same mods done to an engine with more potential (like the 4.2L V6 for example) will net more gains and be much, much easier than to do them on an engine that is simply limited by it's own design.

I hope you understand the point I'm stressing. Never be decieved by cubic inches alone. A lot of people don't know it, but the 4.6L V8 hits the performance 'wall' much, much earlier than the 4.2L V6. That is a fact. I like the 4.6L V8. . .in a car like the Lincoln Town Car. It's quiet, efficient, and smooth as silk. That's what it was designed to do. But in any other environment. . .I consider it the ugly puppy of the litter. The 4.2L V6 or 5.4L V8 are much better choices from a design and potential stand-point.

I'm learning every day from people like you that know what their talking about. I see what your saying...don't be fooled about cubic inches. Its kinda like the chevy 350 its fast but the new chevy 5.3 will kick the ***** out of it stock to stock.

Talleywacker and WrongdayJ please email me and give me some ideas of what you guys are going to do to the 4.2.

p.s. that's a zero in er0ck.

Another excellent example is the Ford 5.0L H.O. (circa 1987-1993) vs. the Chevy 5.7L (same time period). By all rights, the 302 has no business even trying it's luck against the 50 cubic inch bigger Chevy engine. . .BUT. . .the 302 is a tight revving undersquare power making little SOB and could hold it's own against, if not beat, the bigger 350 in stock or modified forms.

Once my plans get finalized I will e-mail you. . .but for now I'm sticking with a turbocharged, intercooled, T-04 hybrid turbo system mod. Once that's in. . .the engine's pretty much done, then I get to move on to my favorite area of modification. . .THE SUSPENSION!!! Hell, I love the twisties so much. . .I may even do it first.

Yet another good example! I like the 5.0 I was going to drop one into my truck. I was going to get it from Summit Racing. It had the GT-40 Aluminum heads and a ton of other stuff. But I guess I'll wait to see what you and Talley can do to these 4.2's.

Talking about turbos have you been to this site yet? I would love to get a hold of one the twin turbos they have.

turbodrivenconcepts is over-rated.

www.proturbokits.com has been building a much better rep and have a better product. This is opinion based on tons of people already.

I have e-mailed you....but I guess you never got it. I guess I'll try again.

At the bottom of this page...http://www.proturbokits.com/testntune.htm ....
it says "We offer 100% in house installation, repair & service. A T-04 Turbo Street Kit w/ intercooler can usually be installed and dyno tuned for less than $1000.00"

That's pretty cheap isn't it?

 

Yes. But that's for installation and tuning. . .not including the cost of the kit itself. Becareful of the tricky wording designed to attract price shoppers. A descent system is gonna cost $2k minimum. That's a bare bones system, T-04/T-03 hybrid, FMU, ducting, and dyno tune runs, and a down-pipe/wastegate controller. Now which intercooler is a source of debate, but that Spearco air-to-air front mount job is looking mighty good. You, know. . .the upgrade unit for the Supras. It's pricey, but whoa! It boasts being able to bring a 15psi charge back to below ambient temperature!!! That is cool. . .literally.

Later ya'll

gotcha...

I gotta admit...This turbo idea is growing on me!

 

Me too.

I have about 7 friends/associates that have or had Turbo Buicks. . .one of them even had the vaunted GNX. Though I don't particularly care much at all for GM products, I have always respected and somewhat admired the Buick Grand National. It's a pretty trick set-up, and one that is rediculously simple to adapt to most other engine configurations. With little or no effort at all, they can easily SMOTHER their V8 counterparts. I honestly believe that a well tuned 4.2L F-150 running a fairly stout boost level (15-20 psi- intercooled) could muster power levels on par with or even exceeding the stock Lightning levels. Torque may be slightly lower, but hp should be right there in the mid 300's torque at maybe 300-325 lb/ft. It is not unrealistic at all. I've witnessed turbo 3.8L Buicks drop 425 hp and 380 lb/ft. on a dyno pull, so I know it is more than realistic to believe that our engines (complete with bigger intake and exhaust valves and larger displacement volume) could produce around this power level. I'm not shooting for that kind of power, though. I won't need it. At our trucks' weight we only need just shy of 300 ponies to run with the L's (stock L's that is) so 325/300 is my goal. Then it's on to the suspension/brake mods. Then I go to Texas to meet with the Talley-man and share my findings and set-up with him. Then the both of us will go and 'brand' a couple of the locals with our 'little' V6's!

I'll be right behind ya! Just don't know if I want to put a Supercharger or a Turbocharger in mine? I just wish the Vortech wasn't the only choice that us 4.2ers have. Maybe you a talley can muster something up? Hey WrongDayJ e-mail me and tell me what your going to do to your Suspension.

I'm working on getting a Procharger 11PSI kit ready for our trucks. availablility will be Feburary of next year.

BTW, Pete is making 320rwhp and 330rwtq with his 4.2. His mods:

Powerdyne 12psi
Mac off road H pipe
Gt mufflers
30# injectors
Pro-M 80mm
and a K&N filter.

He ran a 12.64 @ 111 in his 3,300lb mustang.

This is good for ~ 13.6-13.8 in a 4.2 5-spd and maybe a 14.3 in a automatic.

This kit is NON-INNERCOOLED.

You bolt on a 11PSI Innercooled Procharger on a STOCK 4.2 with 42# Injectors, Lightning 80mm MAF, 190lph fuel pump and a tuned chip and you will be making 360BHP with NO other mods. Torque will match numbers... maybe slightly higher.

Add all you other bolt on goodies and this can up you to right over 400hp.

You can bore your block out .030 and offset, shotpene, and hydroflux your 4.2 crank with longer rods and you'll end up with 4.63 Liters. This alone is good for 15HP and 30ft/lbs on a naturally aspirated motor.

Want me to keep going???
