My customers love the STR they dont want to give it back.

 

Your STR rental customers never express concern that they are renting a car with 126,000 miles on the clock? I don't believe that the typical car rental agencies in our neck of the woods could get away with that....

 

They love the cars especially for the price, you cant even get an economy at my prices. I'm sold out of cars 5 months out of the year.

 

So if you can't sell your STR for what you want, we have a possible alternative...Weld the silencer ports and rent it out...You'll be a hundred-aire in no time! lol

 

Its by far not a get rich quick business but if you love cars and a challenge there is nothing better.

 

My post wasn't directed towards you or your business; side business for a Jag owner having difficulty with selling their Jag...

 

PLEASE UNDERSTAND I AM NOT A ARTIST WHAT SO EVER .

BUT here i have kinda made a template .THE SPOTS INDICATE WERE I WOULD PUT SMALL AMOUNTS OF JB WELD TO SECURE THE PLATE ALSO I WOULD MAKE IT A SNUG FOR NO WIGGLE ROOM BUT MOST IMPORTANT HOW THINK THICK 1/16? MAYBE?

EARLIER IT WAS mentioned to use a aluminium plate rather than weld plugs .
But what should i use to hold in the plate regular jb weld i rather use something stronger. PLEASE SOMEONE CHIME IN

 

i would look at test data from ken bell on porting vs stock. It doesnt adress plugging the ports, but porting showed a .6psi boost increase over stock on modded eaton. and 4hp. this was only on the very TOP END and actually showed a loss under the curve. I personally dont think Ide spend the time or money or even chance the potential for issue based on the data shown to the performance(or lack of) and the potential for problems.heres the link
Ported Eaton Dyno Tests

 

WOW Brutal!!

This puts the final nail in the coffin for me! I always knew porting an Eaton was a gamble but had not seen these results until you posted them.

Really points in the direction of getting a twin screw and just leaving all the Voodoo for the Eaton alone. Porting, blocking sound ports, pulley changes top and bottom.

Avos; Will the TS for the STR EVER be ready???

THESE ARE PICS I TOOK LAST NIGHT. IM INSTALLING A 2.6L TWIN SCREW ON THE 4LITRE IN MY NISSAN AND TOOK OFF THE MP90. IM USING A USED KIT OFF A LS VETTE. DOING A BUILDUP ON ANOTHER NISSAN FORUM BUT THIS IDEA ALL STARTED HERE WITH AVOS. MY LITTLE MP90 AT 7000ENGINE RPM WAS TURNING 16000RPM TO PUTOUT 10PSI. THE KB WILL TURN 9000 TO PUT OUT(ROUGH GUESSTIMATE) 15PSI. I UPGRADED THE MOTOR SINCE IT WAS NEVER DESIGNED FOR BOOST APP. FORGED PISTONS AND RODS AND DROPPED COMPRESSION FROM 9.7 TO 8.5

 

The Kenne-Bell "analyis" is somewhat misleading ... or at least not good science if the goal is to study the Eaton in isolation. Their goal is to show that the Kenne-Bell is better than the Eaton.

There is no direct comparison of a ported versus non-ported Eaton running the same drive ratio.

The dyno curves are for a ported versus ported running two different pulleys. There is no curve for a non-ported Eaton.

 

You have to scroll down and look at the dyno graphs where it says "stock eaton" "ported eaton" and says right in the text they used 4 differant super chargers all with the same pulley size 2.75"
Then we tested 4 superchargers (Kenne Bell BIG BORE 2.6L, Kenne Bell 2.3L, Eaton 112 (1.85L) and a ported Eaton 112 (1.85L) all with the SAME size 2.75” pulley. This is the smallest pulley we could safely fit over the Eaton drive.

 

That would have been yours truly.

The idea was to make a plate that covered the entire area other than the "V". The lips at the two sides would have been to force the plate down to eliminate flopping around. Then generously slather some type of high temp epoxy in the area and bed the plate down.

Note that it was a concept, and has not been actually tried. It was simply a suggestion based upon the perceived shortcomings and difficulty of welding.

 

So, where is it in the chart at the top?

385HP vs 389HP in the dyno graph without any other meaningful legends or notations.

There is no 389HP number in the chart, just 385HP.

This is not a comment on whether the Kenne-Bell is better or worse than Eaton.

It is solely directed at the method of presentation. As it is part of a sales brochure, a certain amount of selective presentation is present. This happens in IT all the time. Vendor tests are always suspect and buyers have to read them very carefully. IT vendors spend literally millions of dollars to win SPEC series benchmarks. At least those benchmarks can be compared apples to apples because they must conform to a standard workload and have rigorous disclosure requirements.

Remember the old saying: "liars can figure and figures can lie".

 

So far I have never seen a dyno that showed any gains from porting. Even Stiegemeyer doesn't have this on his sales site, except for one that was a combined change where chances are the spark plugs would have made most, combined it showed on his page about 3.5%. If it was so good, there would have been plenty of dyno proofs on his sales site right?

 

Can promise anything, but am working on it now, hope to know more in a month or 2.

 

so its risky???
What kind of epoxy would you use hi temp of what brand?
And also how thin can i go on the plate? I dont have a plasma cutter.

 

No idea. The whole thing exists only in the imagination.

Your prototype is the first physical example.

The thickness of the fender sheetmetal should be good enough. Nothing you can't cut with a metal blade in a jigsaw.

 

Well if anything comes loose you will destroy the super charger and the engine is seconds. All for the sake of more blower whine??

I really don't care much about black magic mods with nothing to back them up. You might as well run magnets on your fuel line for a even bigger benefit! Or one of those sweet electric superchargers sold on EBay.

okay i hardly think that in a market of credibilty and the internet that such a large manufacturer like Bell is going to put out misinformation. I agree with Andre on this too. Ive Never seen any info that really showed any gains that came from a REPUTABLE source. I dont see why the arguement over this. it clearly shows that a ported Eaton under the curve LOSES hp/tq. The point being that even if it were a SMALL gain under the curve like the top end. I personally think its a waste of money and time. A pulley change would be a much better choice in return on $$$. I think that if a company like Shelby is going to use a product like Bells with factory warranty that they dont buy into MISLEADING HYPE and would KNOW for themselves the TRUE story of what works and what doesnt. the purpose of my post was not to tout a twin screw ocver a Eaton(although that shows as well. ) But to show that porting a stock Eaton for the most part is a waste of moneyIMO
