Great work Zuffen! Sounds great, and what a speedy job you did too! Keep us updated
Help need Lexus SC400 performance pulley system
- Thread starter WUKWS
- Start date
The 1UZFE EGR Delete Kit is available for sale here.
Guys, guys, guys.
As it has previously been pointed out. people will beleive anything they hear and follow a trend.
I am no mechanic and could not build a high performance motor buy myself with out some assistance but i can tell you this:
You can not touch the water pump or when at idle for short periods the thing will get hot on a hot day.
The altenator you would gain stuff all for the slight decrease in pully size, or that could cause you some issues being a car that has got to be the most electrically power demanding car around for its age.
Power steering pump isn't going to give you much either with out failing.
I mean Peewee is right, for the cost and hassil involved to gain 9/10ths of stuff all, you gain it somewhere else and futher more say you did gain some crazy figure like 10Kw you would be hard pushed to notice it !
I mean these people who use these systems properly and really get any benifit and would say its worth it are Top Fuellers etc.
These guys are looking for every ounce of weight they can strip and looking for half a HP.
I used such a thing on my previous car simply to replace the V belt with a ribbed one for reliability and lack of slip.

Stephen

Peewee,
My mistake.
Personally i find the power steering far to soft and i would rather feel the road so i simply disconnected the computer module for the Steering.
Its fitted under/ behind the glovebox.
Feels alot heavier but alot more responsive, still didn't notice any power gain assuming the pump is working less hence the heavier feel.

While i have you guys,
Being a tight ass and the miss's against anymore money being wasted on cars.
I wanted to get the power up about the 250Kw mark as cheap as possible ( with out her Feeling the missing dollars ).
I was looking at going forced inducted but with two sc14 superchargers ?
Simply for the reason that i can buy two for $500 and i reackon i could have it all running for around the $2000 mark ?
I have tried to compensate for the extra drag on the motor buy removing the hydraulic clutch fan and replacing it with two electric items. Further more sliding the radiator on a forward slant to accomadate the blowers in front of the engine and use probably the pulley shown earlier of the other model.
Do you think this should work and make this power ?

Peewee,
Well i must admit i did question this before and got a reply that the standard Ecu will handle a power increase upto 40% which should put the total output figure around the 270Kw mark ?
It does sound a little out their but so is everything about this car !
If this is true thats great, if not the Ecu is no concern other than the extra dollars.
My real concern is how efficent these blowers are ?
I know they are very small but the two of them should be good for say 7psi its just temperature increase and i really have no idea how much power the two of them will drain from the engine ?

You won't do it with the SC14's, you will need an M90.
That 40% was worked out that pre-supercharge was 121rwkw, and post supercharge was 171rwkw.
That 121rwkw seems a bit low for a stock 1uz, its a 35% power drop from the flywheel.
25% is the max you should assume.
His 171rwkw will be about 220-230kW at the fly.
Stock these motors are only 185kW.
Its the vvti that was 208kW
I'm pumping out 180rwkw NA, and I'd say its about 230kW at the flywheel, if not a little less.

40% is a big ask with $600 worth of superchargers.
Don't you think that if it was possible, people everywhere would be doing it?
You will only pull about 4psi out of them, and that is overdriving them to a safeish limit (read: they wont last 100,000km's).
At 4psi (which you will get at almost redline), you will be lucky to get a 30kW increase.
And that is only on peak power.
Over the whole range, there will be minimal increases

Pewee,
Well you might be right ?
I can't find a great deal of info on these superchargers, well no spec's just a lot of talk.
Talk is often peolpes opinion rather than facts or worthy knowledge.
Firstly people wont look at these items for this application due to there size.
Castlemain Rod Shop uses these blowers on 3.8ltr 6 cylinders and claims a 25-30% power increase with standard pulley and an exhaust no chip ?
I don't know of anyone who has used this kit to verify it's performance ?
I would imagine 35Kw power increase with exhaust in this application possible.
If so this means the blower can supply atleast 170Kw ?
Q1: How much power did the orginal motor this Blower came off ( 1G-GZE ) have ?
Q2: Can it supply it again ? because i am looking for 270Kw, which sounds like a lot but when you work it out is only 135Kw per 2ltr bank.
Pretty close to the original spec's ?
Q3: How much power loss do i get from using two of them on the motor ? this is the the answer not known !
" 40% is a big ask with $600 dollars worth of superchargers "
If somebody put to me the same statement 40% from $500 worth of blowers because that what i can buy them for, i would reply " yeah right "
I am just looking to make some reasonable power from a very susseptable motor with the least amount of cost.
The she keeps telling me, priorities !
Look if you can point me in the direction of any proper spec's about these Blowers, i would be greatfull.
Others wise all you have said is, it sounds crazy and rediculous. I havn't seen any supporting information as to why ?
A car was designed to drive you from A to B safely, the idea of supercharging one to make it capable of getting you into dangerous situations is crazy !
Like is said i would be happy to look over any facts you have.

Stephen
