Need help in getting a supercharger…

What is a good supercharger?
Who makes a supercharger kit for a 2001 LS430?

Please let me know. I want to start gapping these mopar folks.

 

You never will........even 5.7 guys have more power than a 2UR-GSE with little effort.

 

LS swap it.

 

Check these guys out !!
I myself will be fitting one of these set-ups .
Bonus for me is the manifold manufacturer is in Australia , downside is the SRT charger will have to come from the states .

 

There are no kits and why would there be? Our car certainly isn't the right car for any manufacturer to make a kit for it. Sure, you can be like the YouTube guys and custom fit one but remember, you're probably going to need more fuel, a tune, and some exhaust work to make it worthwhile and after all that, you're still in a very heavy car. Don't forget suspension, brakes, tires, etc.

Before someone mentions the Tom's kit, it is impossible to find, would be challenging to run on a US-spec car with the ECU, and they really didn't add enough horsepower to make it worthwhile.

 

Other issue as well is even with all the work they did in the above series it still couldn't keep up with the M5.......and all modern mopars basically start at that level these days

 

These guys used a Ford SVT M112 Eaton Supercharger ...

You Tube

 

aaah, that’s the same car

 

Begging the Colonel's pardon
...you never drove my LS400.with 3UZ-FE engine with extrude-honed intake.

On two occasions I have shut down late model Dodge Challenger and Charger with a "Hemi" badge on the fender..(not Hellcat Red Eye)
Perhaps the owners did not know how to fully depress the gas pedal?

My power button was on and traction control was off.

Heavy Chryslers with large diameter rims - an unfortunate trend from a performance and comfort standpoint, are not conducive to optimal acceleration and braking.

I don't like to get on it too much because the stock transmission, driveshaft, differential (open)., half shafts, suspension, motor/transmission mounts and chassis are not optimized for daily 1/4 mile jaunts.

 

You are not beating any mopars unless they are v6's I had a stripped interior with headers exhaust and a 75 shot and I barely beat a FBO Evo8. So anyone telling you how fast there 430 is is full of it. The connecting rods let go at around 400ish hp at the crank. There is no point in trying to beat them the only thing you are going to be doing is saying my slow car is faster than your slow car.

Also all the power buttom does in the ls400 ls430's is change the trans shift point it doesn't do anything performance wise and the 1uz 3uz power band drops like a rock after 5900 so the power button really doesn't do anything.

 

Do a 1/4 run and report the number, best I could do with my 02 430 (228k) was 14.8 with my very high mileage and a tune and the 06 (69k) did 14.6 with the same tune as well. There is no way I can beat any 6.1/6.4 car and any 5.7 car will be at its worst right ahead of me. My friend has a beat to hell 16 ex-interceptor 5.7 with the Texas speed cam and it out runs anything Lexus has stock. A 6.4 car is just flat out in another world vs Lexus and even against the older M5s a supercharger is a waste of effort.

As far as rim weight effecting braking and handling the late model chargers are superior in both respects in every measured test vs a 400 and 430.....

My 2015 A8 does 11.3 at best and 11.7 with ease on demand though so I don't really have issues defeating hellcats if I feel so inclined these days. I was going to go with a GSF but they are simply too expensive for what you get performance wise, much better quality wise but the fact is it's still slower.

If you can show me a video 0-60 run or 1/4 mile run that beats even a 5.7 car I will eat my shoe. I love Lexus for the quality but they are just not fast

 

If your in Australia why dont you use a harrop blower? Get them to drill the top plate for one and slap one on.

 

A HEMI badged V6 exists?

 

Yah its called a ricer there plentiful in California and florida lol its super easy to glue a badges to a car. There is no way your 400 or my 430 is keeping up with a real hemi sorry not a chance, if my car with stripped interior and full bolt ons cant do it no way your stock 400 with a stock 3uz can.

Your stock ecu is compensating for the extrude intake you have probably changing the power band, to higher rpm in reality it is not doing anything. There is 1200 hp 3uz's using stock intake manifold so I doubt doing the extrude hone intake is adding any power just my personal opinion.

If you do not tune the ecu you are not getting any real power gains the stock ecu will just run its fail safe maps or whatever to keep the car from blowing up.

 

The stated fact that the“stock connecting rods would let go at around 400ish in 1UZ/3UZ” is news to me? I have seen 750hp twin turbo beasts that were still running on the stock bottom end. The 1st gen motors had some extremely heavy duty forged I-Beam Rods and forged crank and pistons. They can be found for low prices and are a direct drop in.
Obviously you can make anything go as fast as u can afford to go, but I don’t think the OP mentioned wanting to take a run at the Street Outlaws Top 10 or anything. That Supercharger can be put together for around $2000 and add more hp for that price than all the bolt ons put together. And if he wants to get more than a 25% increase well he just needs a credit card and he can begin with FarmTruck.
I sure like reading the posts full encouragement a lot more than the people setting everyone straight with their expectations.
