Saleen Supercharger Test


Check it out, not bad for only 3.5 lbs of boost. Can't wait to see what a pully change and a tune will give............. :worship:

The QM times were a little slow but considering the test conditions I guess a 12.80 on street tires and a 12.40 on slicks isn't bad.

 

I think its actually a pretty poor effort....very poor.

 

holy kaka....i didnt think the '05 were as responsive to mods as that...i havent really been into them...thats pretty sweet numbers with such low boost....so, how much can thier bottom end stand up to? and also i know 4:10's aint bad in a 4v engine on the highway, how are they in that 3 valve?

 

Quoted from the article:

"What we didn't count on was temperatures in the 90s, high humidity, and a low barometer reading."


With the testing conditions like this, I'd say a 12.80 isn't all that bad on street tires. heck the Saleen they tested last month only made 390 rwhp and it ran a 12.50

Plus the Saleen probably weighs a good 200 lbs more than the GT so with better weather conditions it would have definitely put down better times.

 

JDM has been running in the 11.60s with their Saleen SC'ed car since that article was written a few months ago.

 

It seems that the current blower problem is not really with the temp, but the lack of a fule pump to keep the fuel pressure up high enough in the upper RPM range. Maybe it is just me, but it seems like that is the current dilema for the tuners/blower people

 

In stock tune they're pretty lame. I've run against a couple of stock ones and I'm neck and neck with them running N/A with a clutch that's starting to slip and stock gearing.

The modded JDM Engineering car is quick. I've seen it run 11.69 on stock inernals.

The Saleen is a good blower inverse 2.4L twinscrew with long runner lenght for low end torque. The problem is going to be getting enough fuel for high HP. Not to mention MAF voltage.

Kenne Bell Boost-A-Pump for the former.
Diablosport Mafia for the latter.

Even then hyperpathetic pistons and crapped powdermetal connecting rods.

Forged bottom end for up to 600hp on stock block.
Teksid block with forged internals and custom engine mounts for up to 1200hp.

 

The problem is not new and the solution is out there and proven to work.

The Kenne Bell Boost-A-Pump. Here is the theory of operation. It's very interesting.

 

based on the dude who blew his motor already after 9 lbs of boost---sounds pretty darn good to me----IMO---between 4-500HP on the streets is pretty tight---enough to spank the rice, give vettes and the like a whoopin---

 

I am wainting on my Saleen SC to arrive any day now....

After reading about everything I could on the Saleen SC, here is what I found.

1) You have to upgrade the Injectors to avoid running lean at the top. The Saleen kit does not come with these.

2) You have to put in a higher capacity fuel pump or a inline boost pump. My installer is adding an inline fuel boost pump ( not sure of which one, but it is probably the KB unit )

3) You really need to get a custom tune. The Stock tune has the timming heavly retarded and the fuel is too rich down low and too lean at the top ( trying to compensate for the lower # stock injectors and lack of fuel rail pressure ) Also, the stock tune is for 91 octane.

4) The mass air sensor is fine ( with the stock pulley ) unless you exceed the stock rpm limit of 6100-6200rpm.

5) If you really like to thrash the car, have your tuner disable the Traction control. This system pull back fuel and not timming to rein the engine powere in. This of course makes the engine run lean under heavy stress for short periods of time.

Regardles of what someone tells you, any power adder that adds more than 50hp or so may make you engine go boom... I would never add this type of HP unless I can afford to rebuild it and be without the car for an extended period of time.

Having said that, I do think that I can get around 400rwhp out of my car ( auto ) and still have a reasonable life ( 50-75k MILES). All you can really do is get with a reputable tuner and let them do their magic to reduce the odds that your car will go boom.

YOU ALSO HAVE TO USE A LITTLE COMMON SENSE.

The way you treat and maintaine the car will have a big effect on engine/drive traine life. Thrash the car all of the time and it will not last long with or without power adders....

 

Define thrash

There's a lot of truth and common sense to what you say

 

These numbers sound fishy. You sure they aren't estimating crank horsepower? ~365 rwhp? They need a better driver reguardless...

 

Didn't people say a few months ago that the Saleen at 4psi was getting like 350 at the wheels?

 

If all you do is slap on the Saleen SC and use their basic <ultraconservative> tune, that's about right. But if you upgrade injectors, MAF, etc., and get a custom tune, you can get much more hp, still at low boost. Then, if you want to change pulleys, upgrade the exhaust, etc., you are easily up in the 430-450rwhp range.

 

i could not agree with you any more well said i ran 12.20 stock motor mods in my sig at #3620 well worth the cost of the saleen $40000 not.

 

For running the 1/4mile the bottle is ok

The only problem is that the bottle will run out sooner or later.
Hard to compare to a N/A or forced induction car which has the power there all the time.

 

He ran 11.5 on the bottle bro.

 

Hay Stanger. when you do the install post lots of Pics. I think I'm headed down the same road. Not sure if i'm up to the install myself though.

 

Bottles are for babies!

 

So Saleen covers factory warrenty? Just curious.

Im considering this s/c or the ford whipple... And suggestions/tips?
