Seems we see a lot of prototyping out here. I believe the last get together Jay and I attended had a Works 140 strapped to a 99


Jay, are you going to John's this comin wed?

 

Flying ****, I'm planning on going to John Whalin's on Wed.

Those who attend might get a sneak preview of a new Lightning part.

 

Perfect! That is exactly what I am looking for. Why mess around with this and that when a new blower can add more safe HP for the same or less money?

Plus, it seems like the blower could be swapped back out fairly easily for warranty work, right?

 

That is exactly what I am asking. A twin screw will provide more efficient (cooler) boost at any given PSIG. 15 PSIG on the Eaton (out of breath) and 15 PSIG on a twin screw (in its efficient range) are two different animals.

The question is: How much safer is the twin screw (a true compressor) on a stock block at sane boost levels? Can I run 15 PSIG on a stock block (and with the stock chip) without fear of detonation?

If so, I'd spent that $3,000 in a New York minute.

 

Tim, I definitely invest in some dyno tuning. When you are moving that much air, you neeed to have the fuel right too!

Beyond that, there may be some other mods, too.

 

Sal, can the #4 spark plug be changed with the upper intake on the Works 140?

The 99 prototype I saw in Southern California recently looks like a great setup, but with that upper intake there was no access to the #4 coil and plug and fuel injector.

Does the upper intake have to be removed for complete plug removal?

 

As of right now, yes. But that's the sacrifice to be made for the proper airflow for the rear inlet. It's really not as big of a pain as it seems. The blower is easily removed if need be, and you can just unbolt it and swing it to the side to change that plug. I think Works is working on a revised intake for the future that helps with that issue, but I don't have the details on that.

EDIT: Actually I was told that you can get the #4 plug out without blower removal, and that it has been done. It's a tight fit, but it can be done.

 

I'm with tim here. I'm very wary of modifying the truck with pulleys and chips, and a more efficient blower just makes too much sense to ignore. With a works 140 at a safe psi (lets say 12 or 13)

I would love to be able to have a setup like that, without a chip (that takes away the flexibility of the unchipped PCM) and easily push the truck into the magical 400/500, or maybe even 450/550 with relatively low risk. I would much rather spend 3K on this than 600 or so on the classic "chip filter pulley", which comes with the risk of having a tank of bad gas, or a sudden change in weather, and getting a block ventilator free!

 

You guys are nuts to even think of running 13 to 15 lbs. of boost without any way to tune it. And what does bad gas have to do with a chip? Your truck can be tuned to be way safer and have more hp with a chip. Don't take my word for it, ask Sal since he started this thread. 15 lbs. is one hell of a lot of boost! With a chip you can calm it down so it will (hopefully) live. If it detonates it will go boom with or without a chip. A chip from a tuner that knows these trucks is probably the best mod you can do. Way better than any blower! What good is having all of these mods if you have no way to tune your truck. Trust me, no tuner wants to hear of any Lightning blowing up. They want to be on the safe side. We are the problem, we keep asking them for more! They give us more and we are happy for about two weeks then we are back begging for more power. It isn't the chip, it is us. The chip just gives us the means to go off the deep end. If you still do not want to put a chip in it, drive it easy after you up the boost until you can put it on a dyno and check to see that everything is ok. You would not put an engine together without checking clearances, so why would you run it without any way to tune it. Skip

 

I know I've asked before but I dont think I've ever gotten a good answer.... what does the works blower sound like? I'd hate to give up the Lightning's signature sound, even if it means more power. Can anyone who's seen this blower describe what it sounds like? I've heard a KB and that rattle-trap always sounds like its about to fall apart

 

Sal,
What a curve! Well done.

I agree with Skip. Ford safe-tuned the truck for 10 lbs. boost. If you up the boost you're out of the "safe tune" parameters.

I don't agree with the economic premise by some that a blower kit will be cheaper than chip, pulley etc. to 15 psi. Last time I looked at the new blowers it would be over $3k plus. 2 way chip, pulley and plugs to about 15 psi is a lot less. The new blower may be safer and more efficient but it won't be cheaper. Oh yeah, we'll have to wait and see how many new blower guys blow plugs or rods.

 

would think a 380 hp truck just "not enough" ...you guys kill me sometimes.... what exactly is fast enough? I couldnt imagine driving my truck every day on the street with 500+ horses....just not needed

 

Sal,

I don't know if you caught this or not; so, here goes. Every dyno I've seen for these trucks, has had the torque numbers closer to 700 lbs/ft, when the HP numbers are this close to 600. Is this not true with the twin screw SC? Can someone explain why the numbers are so close here? Does this truck have 4 valve heads or something. You'd think that a 2 valve head engine would make more torque than that, at that hp level.

 

I read where some guys were asking about #s on a stock bottem end truck. My truck has a stock bottem end with a kenne bell. It has no mods to the heads or exhaust at all, it made 460 rwhp on Danny Swansons dyno. I made those #s with only 15 #s of boost. I have a filter, throttle body, and chip and that is it besides the kenne bell.

 

Well, I've never seen dnyo numbers from a truck that layed down 600/700 numbers

But your question is valid, usually torque is proportionally higher. As I mentioned in the other post, this truck was squeezed in unscheduled on the dyno, so there wasn't much tuning done on it. The A/F was too lean on the bottom end, which is why the torque is lower than expected. Once it gets fattened back up, the truck should make well over 600ftlbs .
