I never said special...i just said I have yet to find any engine failures..... There are plenty of engine failures with "other" superchargers...... do the math yourself. I'm not knocking any S/C company.....but there has to be something thats holding our motors together.

 

I THINK what Lee is trying to say is that yeah, there are a LOAD of people running JDMs tune for their Series VI setup.... but that there are plenty OTHER folks out there running the blower (not using that setup) and that there hasn't been any general knowledge of a Series VI blown car executing the engine.

 

Thank You

 

Low boost is holding them together. People who put Kenne Bell blowers on and hit their engines with 12 PSI and rev to 6500 RPM blow their motors. If you pulley the KB to 5 or 6 PSI it's just as reliable. Keep in mind people with Saleen blowers aren't running the same power levels as people with "other" superchargers.

The obvious thing here is that it isn't some "special" thing about Saleen's blower, it's just that it isn't much boost.

 

I'm running close to 10 PSI and my redline is set at 6800 RPMs.. I would hardly call that low boost! Revving to 6500rpms isn't blowing the engines......keeping it at 6500 RPM without proper fuel pressure is what these motors don't like.

 

I would call 10 PSI low boost.

What's your A/F thoughout the RPMs? Have you tried a 2/3 shift at 6800 RPM?

Is every Saleen user running 10 PSI? No. Most will be stock 5/6 PSI. Hence the lack of failures. Boost is boost. There is nothing special or unique about Saleen's blower other than that it is less efficient than a Kenne Bell

 

maybe.....but i'd rather not replace my internals yet..... My a/f is well under 12 all throughout. I have the saleen twin GT500 pump setup.....It's actually closer to 11.5

 

If you want to talk about efficiency......should we get into the KB tensioner problem....or the Blow-by???? Maybe belt slip????

Once again.... I never said SALEEN was better..... I was just stating the facts.... hi boost, low boost, or no boost....the facts are the facts.

 

Exactly. You aren't running your engine hard. ( smart ). People who kill their engines are drag racing with high boost and hard shifts and high RPM.

 

Sure, I'll be nice enough to correct you.....

Ask Mark (CK) about blown engines..... here's a thread from a year ago- there has been plenty of blown engines including the Saleen blower. Thread: http://www.modularfords.com/forums/2...t=blown+engine

Don't misunderstand me, I'm not trying to degrade the Saleen unit, but my point is that its the TUNE that is most important when it comes to engine lifespan.

 

Agree with tom. 11.5 a/f is VERY conservative and safe.

 

Just throwing this out there:

'stock' on the Saleen Series 6 (2.3 liter) is 3.5 to 4 lbs of boost with 465hp in the 2007 model

Kenne belle 2.6L blower at 5psi is 471hp (straight from their site)

Looks pretty similar if you ask me, even with the .3 liter difference

I would say that the Saleen unit will not hit the HIGH max power ceiling the Kenne Belle's are capable of (ie - 20psi and on) but talking about street driving, I wouldn't say they are less efficient.

 

What you're saying is true whether you are N/A or S/C. The guy started this thread to get our opinions on a SAFE s/c for a daily driver. All I said was a JDM SALEEN kit is a safe way to go because THEY haven't had an engine failure yet....out of over 500+ kits. That story on Mod Fords has nothing to do with JDM's Saleen kit. So I will agree with you......the tune is most important........With any supercharger keeping it under 10 lbs of boost with low A/F and timing will have the best chance of survival. I'm only at 16 degrees of timing.

 

No, you didn't just say "they", you said "any" which is not true. Get your facts straight before making a statement that implies anyone, anywhere can buy a Saleen blower and have ZERO engine failures. The thread on Mod Fords has to do with your statement above (post #19).

Now.......

 

Just to chime in here, I'd say that PSI per PSI on the KB or Saleen, your going to get pretty equal results, with the same tuner...
The power and safety come from the tune...

If ya wanna bicker about 5hp or whatever between the two then go ahead...

For a street machine that has no expected or very limited expectations of seeing a track or dragstrip, I'd say Saleen...only cause the install and look is fantastic...plus it's quiet...

IMO is your gunna go with huge power, get a turbo setup...

The biggest advantage the KB has over the Saleen is the fact that it can go to bigger power, but then your talking about a whole new ball of wax...

I dunno man, I'm thinking that anything over 450 definately over 500 RWHP for a street car is asking for all sorts of trouble.

I dunno about you, but I know I'm gunna wanna use that power...I'm at 400RW now, getting a smaller pulley on Monday, so I should be up over 450 and I'm kinda wondering to myself WHY??? The short answer is: Because I can, but in reality it really freakin sucks not being able to unleash all that power on a regular basis, worrying about John Q. Law busting the ever lovin' **** outta me and my over powered street rod.

Just hitting the end of 3rd gear is enough speed to warrant a Free Ride Downtown... and that sucks... and whaling thru 3rd is like a 3 second ordeal...So you can get into a lot of trouble real easy and fast.

Not to mention burning rubber and reckless driving laws...

Ya gotta be careful, and smart....

Not ta getcha down, or sound like a turd, just stating the facts...

I still wouldn't trade it for anything though...It's addicting and fun asa ****, but a lot of times it can suck cause your always being cautious...

The other thing is the fact that these cars and the sensation of speed can very misleading... For example, crusing along in my minivan at 80mph seems like I'm really moving along... Cruzing along at 80mph in the Stang seems like I'm not going fast enough...and knowing that she'll pull like a **** at 80 can lead to a lot of potential to go faster... I went thru the same thing on my crotch rockets...but for some reason felt like I could get away with more, and just get away period. I don't think I'd try and run in a car. It just seems too easy to follow... Not that I would ever condone running, but the people who ride I'm sure can relate.

Anywhoo, enough rambeling...just throwin' down some thoughts.

 

I agree. I think a positive-displacement type is best for the street because it doesn't need to be revved to make power...makes you feel like you have a big block under your foot (so I hear). If Kenne Bell is preaching the truth, then RPMs are more dangerous than high boost anyway. Stay around 10 PSI and around the stock redline (6250 RPM) and I'd guess things should stick together.

 

Dude GOOD post

These cars can definitely be deceiving regaarding how fast you are going - I was coming home the other night on the interstate at 80mph and some a-hole in a white Mercedes coupe was tailgating me for a mile or two

I let him pass and decided to stick with him
He though he could lose me
umm NO

I was amazed how instant the power was at 80mph on a downshift to fourth - heck half the time when I was just tailing him from maybe 6 car lengths back, I didn't even downshift - I just floored it in 5th and he'd pull away at first and then I'd reel him in.

Finally he got caught behind a truck and I was in the fast lane - he came up on the right two lanes over gunning - as he was coming up even, I downshifted and WENT and it was like going to PLAID in Spaceballs.... I looked down and I was at 120 and got the hell out of it asap........

I am no super race nut but at times, the speed IS addicting - you just have to moderate and be real careful. Heck after dynoing and custom tuning last week, I am even thinking about bumping the 3.6 pulley UP to the 3.8 just to take a few PSI out of her (considering right now I am running what some folks are running on the 3.4 pulley....)

 

the problem is not getting into it

 

Kenne Bell 2.6L at 8 psi since August '06.

I haven't had a single issue...No belt slip, no tensioner issues, nothing!

Just fun-filled, action-packed driving!

I'm a conservative yet spirited driver. I make sure to hit WOT at least once a day.

It's all about having the proper setup (tune, fuel system, suspension, brakes) in order to keep your motor together and your car out of the walls!

For a daily driver, like mine, I recommend either the KB, Whipple, or Saleen. Each of these have proven themselves to be great performers!

I prefer a twin screw, so sorry for leaving out the centri guys...LOL!

 

Very good info. Oh and having driven a few 1 liter crotch rockets I know what you mean about temptation and that almost unstoppable feeling that can come from too much power.

On the blower issue the Saleen looks the cleanest. The Whipple and Roush are available with factory warranties (unsure of the saleen). I personally would choose the whipple with the ford tune for warranty sake
