Power enhancement ideas

Recommended Posts

Gentleman:  I have played with my LN3 3800 for 7 years and in that time I have tried several  changes to increase horsepower.

But I have settled on the  last one as the best.

1-- I bored out the block 30 over.

2 --installed 95 pistons.( 9.8 to 1 compression)

3-- installed a custom ground Crane cam.

4-- Heavy duty valve springs and retainers.

5-- Ported & polished, intake runners, supercharger, Heads. exhaust manifolds, and Throttle body.

6-- Removed the canister and run the intake down thru the hole in the fender well, with NO 90% turns.

      (This allows fresh cool air the enter the engine)

7-- installed water/ menthol  injection to cool the supercharger.

8-- Installed a NOS system with a 50 hp pill.

9-- Ceramic coated the, Intake manifold, throttle body, Supercharger, and exhaust manifolds.Installed a (all inside and out) 

      including the impellers.

10-- The Supercharger has a  2.5" pulley. (smallest one you can use)

11-- Excell coils and  E3 plugs.

12-- electric switch on the Supercharger that shuts off the vacuum to the bypass.

          (Allows more boast)

13-- Installed a oil filter mount and external cooler. ( allows use of the larger filter)

14-- Adjustable, advanceable fuel pressure regulator.

15-- 36# injectors.

 

As for the switch on the lockout, I have used that foe the past two years.

What are your thoughts on the switch and  having the converter lockup turned off?

I have the switch hooked up so that I can lock up the transmission when I turn it on. 

When it is off the transmission acts normally.

Thanks for posting details Jon, that's an impressive list. I would think that should perform admirably. If I may ask, did someone do a chip for you? I too like the look of the body colored air dam.

I have actually thought about doing just a supercharger bolted on my engine and changing the pulley size to give a very mild boost that would be easy on the transmission. I never got really serious about it but I did check into it a little a few years ago. If I remember correctly it might be possible to do without swapping the whole engine.

ive thought about that too.

I probably had the best opportunity of all of us this last spring when I did the engine rebuild on the Red. I worked with 2seater on some "upgrades" and ended up with almost 200 HP which is just about right. I am happy with the driveability of the car.

  This spring I pln on installing some new injectors and may drive mostly in the "Drive" setting around town for better throttle response. I'm 61 years old now and I don't have to be the fastest car in the valley, just fast enough to stay out of the other guys way.

If I ever have to rebuild my engine I will probably do it the way you did. I like the idea of having a supercharger bolted on so i might check into doing that while I had the engine out but I doubt I would do it.

Yes, 2seater, I had the chip done by "sinister Eng". It has 5 setting that I can control

!- normal + Water/Methanol.

2- Water/Methanol + NOS.

3- Just NOS.

4- No assists

5- Valet, Won't go over 50mph 

 

PS- All settings include the Supercharger.

That looks excellent. I am familiar with Ryan's work and I really like what you had done. Thanks for sharing.

Oh, buy the way, if anyone cares, I also use 30% Nitro methanol in my 

water/ methanol system .

 

That's such an insanely powerful setup- I'd be scared to drive it. I think Quicksilver is awesome.

I briefly mentioned the sort of outside the box idea some posts back, adding a centrifugal supercharger. I am considering trying the Eaton roots type blower as GM did it, but finding good parts is a bit more difficult than first thought. That brings me back to the possibility of a centrifugal, like a Vortech, Paxton etc... What I cannot seem to find on the net is dimensional information for the blowers themselves. After looking at the belt diagrams for a supercharged engine, the alternator is moved to the top rear and the power steering below it. It got me to thinking with those items moved, the space for the alternator might potentially be at least partially used for a belt driven centrifugal supercharger but I cannot find any actual dimensional info, just kits and such that are engineered for specific vehicles. Has anyone run across one that can offer some general overall size info?

I appreciate the pics but I am looking for information on a belt driven centrifugal blower, specifically a line drawing or similar with dimensions. Something like this from the Paxton site. It looks like the compressor side of a turbocharger with a larger inlet due to the lower speeds from the gear box on the other side.

 I'm at loss as to how carbureted Mustang parts relate to the Buick Reatta?

2seater needs a "line drawing with dimensions" and that's what I found. If it's useless to him- he can say, then I'll delete it. I'm sorry I couldn't find a diagram labeled "Paxton Supercharger to Buick Reatta installation".

It has no direct bearing but does get closer to what might work on our Reatta. Information on the dimensions for the remote mount belt driven superchargers is scant on the net. Sometimes a loosely related installation may inspire further research.

I'm all for having a topic about performance enhancements for the Buick Reatta. However, all the photos and links to other sites that are not about the Buick Reatta is getting too far off topic.

This is the reason I asked for input. This is one of my engines on the stand with the alternator removed. Minus the tabs that the alternator mounts on, the clear area is 9.0" wide and 7.0" deep measured from the fuel rail to the tip of the water pump pulley. The kits that are available for more mainstream installations are far more expensive than swapping an entire factory supercharged engine in. But, if something like a centrifugal blower might be scored in a swap meet or junkyard wreck, perhaps there would be possibilities, hence the request for dimensional information.

Do you want to retain you turbocharged setup and add a supercharger?

Or remove the turbo and install a supercharger?

Different Timing Cover, bore your own CMP hole, or just use an electric water pump, and remove the OEM. Remote electric oil pump & filter. Delete AC compressor. Get a plain PS pump like a Honda, with remote reservoir. With DIY brackets, bushings & bolts- you've got many possibilities.

I presently have two complete engines, both are turbocharged. The one in my example photo uses the entire engine to feed what is essentially an early GN turbocharger. It was not intercooled the first time around and in the meantime I rebuilt a second junkyard engine, twice (which is a separate story), and that is what is in the car now, fed from the front cylinders only to a Ford 4-cyl turbo. I am now putting together parts for a third engine which is at the machine shop now. After seeing what is possible with a supercharger, I though it may be a good time to try a different direction and check out the s/c world. The factory setup would be the most well explored and would be my preference if I can find the parts. I do admit your twin-charging idea is intriguing, but that might be for later.

I agree.  What you need is a supercharger & throttle body from a 95 or 94 Buick pontiac or olds, the intake manifold, front alt & power steering bracket and  p/s pump.

If you get parts from a bone yard, make sure you get the heater hose outlets.  If you find one that is complete take everything off the top of the motor including the throttle cable bracket and the reserve tank for the power steering pump and injectors.

I have some spare parts that I could let you have.

Jon..
