Powers laser slide gains?

[David - WI]

A dyno of before and after a slide install with no other mods would be excellent. The motor could be modded it doesn’t matter but the dyno test should be the exact same motor showing only the difference with the intake swap. If these things make solid gains this is sure to sell many

Wait... the 15hp is for just the throttle plate on the "small" 150hp - 225hp 3L "ProMax" Laser motors. https://www.powerperformanceengineer...-intake-system

On a 2.5L 200 he's talking "bolt-on" 67hp. https://www.powerperformanceengineer...erformance-kit

The big-boy setup is for the Drag/F1 horn motors: https://www.powerperformanceengineer...ide-intake-kit

“200” what 200? What’s the front half consist of? Which casting was it? 267 from a non ported 200 with a four or small five petal? Finding that hard to believe. The only gofast parts on that list is the ecu, the six hole laser slide, and the shaved heads. Am I missing something? If that makes his motor 267 the motor I have right now should be an easy 252 seeing as the gains listed for that laser slide are noted at 15hp.

so heads and an ecu make 252 horses from a stock 200? What? How? Unless I’m seeing this wrong the slide must make boat loads of gains on a 2.5 laser.

You're mixing 2.5's and little 3 liters... you should just contact Brendan.

i just wonder if the slide intake area[wot] is greater than the laser open area, or just a straighter flow path? probally they want you to turn the motor higher to show a gain. im sure mercury tested bigger intake cfm units, why not produce a 240 pro/max? direct injection is the way.. imo

if you look at the back side of the laser intake there are only 2 sets of butterflies for air intake. The slide intake opens all 6 cylinders to an front of the motor air intake. Much more air in, more fuel needed, more power!

This is on a dyno, open exhaust, and plenty of hours tuning and tuning the fuel curve and pressure to the dyno room environment. on the laser setup.

Everyone remember, there is a slide intake for a laser setup and a slide intake for a 260/280/drag crankcase injection.

I have not ran one, but I don't think you will see that much of a gain with the stock box if you can even get it to run well. Still limited for RPM and I would think you need to adjust the curve, not sure you could only adjust the fuel pressure to get the slide to work, or work well. Has anyone tried to run a slide with a sock 225 PM merc box?

A Monty V-6 OMC on Powers Dyno .. slide activated ..

Idling around the docks, in and out of gear .. maybe a lil snotty.

As stated, not known to sip fuel like a new Kia.

However, from when the column of air gets moving to when the tach needle is facing down towards Asia .. not much else, induction wise can hang with a slide system.

Alright this clip shows the details on how this thing works. It uses the stock 4 barrel butterflies, but when you go wide open the front six holes open up. This is very interesting and until now I had no idea how this thing worked. A completely different unit than the crankcase injected slide fronts. This Powers laser slide probably drives just fine and gets the same fuel economy at lower throttle positions. Pay close attention to what he says just after 30 seconds. I like it

I wish these pics still showed up. It sounds like he did something similar

I was going to get one for my PM, but ended up going with a horn swap/crankcase injection front. Those 225 PM horn motors run very well also. I have the parts for the most part. I want to put the 280 on the shelf and run steel bore for a while.

What power range you aiming for with the steely? Im looking 260+

I dont see any reason not to aim at this powers slide especially now that I see its basically a double intake which is appealing to me for the double duty aspect. I dont always run wfo and would like to keep my range where it is. I can run 80 miles on one tank which is a good run. I'll most likely get a powers ECU as well because im sure he can load it with a sound starting point for his own intake design which is also appealing. I have a line on a lightweight aluminum merc flywheel which is probably what I'll run but if not I'm considering Buckshots lightweight fly. I'm a little leary of these ultra light flywheels though Id prefer to stay merc stock there. I have a couple stock steel 16's which are pretty light compared to the 40 stuff im running now.

Combo is Looking like this;

2.5 steel sleeve
-hogged out chest
-260 or maybe even 300 spec ported sleeves
-seven petal front half
-16 amp conversion with lightweight flywheel
-33cc heads

hotrod fuel system with regulator for fine tuning

I might run that combo with my stock laser intake just out of curiosity. The guy helping me with the porting seems confident this is good to go so I might give it a crack.

Most likely this build will include or at least end up with he powers slide and ECU as well. Then I'll stuff this motor on and keep my current one as a back up. If I could have this built for next summer I'd be good with that.


I'd still like to hear from anyone who runs one of these Powers laser slides just to get some first hand feedback on the plusses and minuses of it.

[rjdubiel]

250+ for my PM with a horn. On FB there are a lot of guys you could contact i bet who have the laser slide.

I spent some time searching the archives here and way back in the early days T-Rex built some laser modded motor he called a ten pack? I couldnt find any details other than it worked very well. I wonder what it was or what it looked like? I also found a fiar bit of content regarding the VST and filter being large restrictions to airflow for the rear facing throttle bodies. That makes some good sense and although I have my fuel system really well sorted I have to wonder if that is whats kind of killing my high RPM? The motor runs strong and pulls hard to 6K then just kind of falls off except for last fall when the air was cold it ran a lot harder then. I wonder if airflow is an issue for the current motor? I guess the only way to find out is to swap it out and see.

Just when i thought I had it all figured out? New information pulls me back in

[rjdubiel]

In my opinion air in the intake is not the issue on most motors, its the exhaust out is the constraint and could hold ya back if running a bass mid, maybe???

[LakeFever]

Yeah bass mid with the liner all stock. 200 tuner. I did port the adapter plate out to the big rectangle but that’s it. You think there’s gains in the mid? What do I do here drill the liner out and add reliefs?

I do have a smooth back I just didn’t bother with it for weight savings

[KIRCHNER]

i dont see how it can flow more ; the laser butterflys are still in use if the slide replaces the stock cover?? isnt the motor still feeding off the 2 stock sets of butterflies?? i dont get it, the butterflies are still behind the 6 slider holes?
