I have 1:ernaehrung004:

Thanks for all the info, i'm more confused then before. For every plus there is a minus. I need dependability. Mercedes has been really happy with the coverage we have gotten for them. They want to be more involved and want us to do some other things. I have had a lot of down time this past year, (not for any one reason) but that was a something brought up in our meeting. I have to figure out the best way for me to go. I appreciate all the feedback.

Yeah yeah Bro you sell Whipples!
The 980 was the best!

Dustin,

I believe you know Tom Earhart...................
572's Twin Turbo's 21 Lbs of boost 1,500 hp. Very Low compression. Full EFI and they are very fuel effiecient.

NO Turbo lag, boost at 1,500 rpms

NEVER any problems with the bottom end and the valve train is changed every 250 hours. How is that for reliable??

Tom has an incredible package and so gentle all at the same
time. And there is something about a V-bottom out accelerating a CAT that........... Well always raises question marks.


Ask Check300 he runs Tom's engine too. I think the dyno sheets would blow your mind for low end torque and no turbo lag. Tom has it figured out!! :drink:

Jon

You guys need to bring that Talon out to some of the large poker runs and hook up with some of the big guns. I dont think 1400 hp should be breaking drives,maybe shorting the life.
Many 40-50's running turbines with 1800 hp with no problems.Might want to look at a different drive builder. Just my 2

Niiiice now thats what im talkin bout :ernaehrung004::ernaehrung004:

Did Randy deduct for your senior citizen discount!! :evilb:

Yes he did and i put some on your Mastercard &the rest he wants to be paid with T & A :grinser010: that is Ok ??? Lmao

Jon,

I don't know Tom E. Turbo's can make insane hp, but never, ever can it match the throttle response and low end torque. Simply can't. You can use all the tricks you want, all the different versions, which again will make insane hp, but cannot fill the cylinder as fast as a efficient positive displacement sc. I've been part of some big projects and I've seen them very close, but they're not the same. Certainly not the lag of the old days if done right, but its still dependent on the airflow through the exhaust.

I'm 1 person who never knocks turbos. They make great power and are great products, just anything, there's good and bad setups, but when done right, they're hard to compete with.

Dustin

This is just an example. It happens to be a pair I'm building now. Remember, they have hyd. rollers and only turn barely over 6000. They could make a hell of a lot more, but that's not what this customer wants. He can't handle 1400, he doesn't need any more.

Lubejob,
Y are you fighting the inevitable.
This is the only blower you need, and you know it.
Give me a call.

I knew it was a matter of time for you to chime in!!

that is pretty reliable power. :drink:

YEAH!

Lets see if hes got the Cunyongas:drink:

I Put A Few More Pics In The Photo Section, How Do You Post Them Here?
I Added In My Psi Blown Combo.. 58 Lbs Of Boost

Hopefully we will finally land a larger more efficient hull this Winter and partake in some of the out of State rain deer games in the Spring,that would be fun!

This heavy rig with 11% slip factor is set up more as a drag boat at this point and is out of hull in the mid 150s not in the same league as the big boys.

Tuesday's failure was a snapped prop shaft ,not an explosion.

Craig Colabella is one of the best #6 guy's we know and is keeping us out every week.

Craig also agrees that #6s are not designed to handle the sustained torque that some of us are throwing at our rigs on a weekly basis especially on a heavy less efficient hull like ours.
Sorry for the high jack Gino!

Really ?? Care to compare dyno sheets from 1,500 to 3000 Rpm's ?? Can race from complete stop or 35 mph if your worried about your drive. Guess I need to correct yestedays post too,..............Boost comes on a 1,300 rpm's

So if your throttling the waves less than 1,300 rpm's I guess you do have a problem. :drink: Like I said Tom has it figured out and well aware most other's don't. There is no Lag, ZERO, NONE.


So care to compare Dyno sheet's from 1,500 to 3,000 ?


30' Single Engine Checkmate,
6.4:1 compression, 21 lbs of boost ..... Boat, Rocks !!
#6 Drive 1.24 gear
29 p Prop


Cheers
Jon

Good to hear he defyed the laws of physics, good for him. I've never had a dyno hold any power below 3000rpm, but I can tell you I've been in a few boats that required WOT at 1200rpm to get the boat going without ventilators in the prop areas.

JEEP?

LOL :ernaehrung004:

a turbine powered Jeep that runs on nitro ... lol

Ha I knew it too Gino. if 1850 a side isn't enough........ you can super size it with 3150 HP a side. (below) :)


Come dance on the dark side my friend......

Funniest post all day:drink:

Are you saying you can't produce the numbers then?

I'm willing to cover your airfare out here, Show you the dyno
numbers real time, and give you a ride showing there is NO Lag.

If my statements do not prove out you owe nothing.

If my claims hold true and we prove the low end numbers plus carry them all the way through and give you a ride showing there is no lag at all. Well then you pay for your air fare and let OSO know these claims are indeed true. :drink:

So what do ya say to that offer???

By they way pops right on plane effortlessly with out a ventilator tube.

Cheers
Jon

6800 peek ,boost at 22pd :eek:


I know alot of the street car shoot out guys are useing that style blower,But look at all the big hp makers are still using top mount blowers

with the biggie fryes too:drink:

I can attest to that

he has em
 

hear his new wife Renea will be flyin choppers soon, he will need to step up to turbines in order to keep up with her LOL :food-smiley-009:

Hi Gino: I got your email. Paul will be in Key West so you can discuss the details with him.

Some food for thought for this thread:

Heat Load

Boost is just a measure of how restrictive your heads and cam are. An engine that makes 1500 HP @ 15 psi needs 22 psi to make 1800 HP. So the question is "How to deal with the high intake air temperatures at this pressure?" By using an intercooler core that is 900 in3, almost 3X as big as the double core intercooler used under some PSI.

Mechanical Load

With the pulley ratio on the primary belt, the input shaft on the twin blower gearcase is spinning at ~12,000 RPM. With the pulley ratio on the secondary belts, the input shafts on the blowers are spinning at ~15,000 RPM. The Vortech step-up ratio takes this up to ~50,000 RPM at the impeller. These are big numbers, and belts and bearings have to be able to cope. We have found that it helps to split this load up between three short belts, but we still increased the size of the bearings in the gearcase and switched to ceramic balls.

Cylinder Pressure

At 1800 HP you have to ask how much more cylinder pressure can the engine stand? I would really like to see a robust 12 cylinder engine developed for this application. 50% more cylinders to share the work and 50% more holes to push the air through. On such a platform the goal would be 2000 HP @ 6000 RPM and 15 psi.

I guess it's a sign of the times; I'm starting to value reliability more than speed.

Just finished some testing with Tom Robinson of R-Tech.
Very inteligent man, great guy to work with and great product that really works well. We will post some number's once we get some more data. But it was really nice of Tom to take the time to drive here from Canada and be a part of this.

Below is a picture of Check300's engine pulled out for the winter for cam research Hence testing intercooler's at the same time. Old cam we started pulling and making boost at 1,750 Rpm's, New cam we started pulling and making boost at 1,850. R-Tech's product really increased the bottom end and mid range too. Boost can be made low and the throttle response is NOT lacking in any way shape or form with this set-up!

Anybody pursuing intercooler's etc., really need to get in touch with R-Tech !!

Thanks
Jon

Are those Dana's exhaust manifolds that you modified?

Nice! :cool:

Hey cougarman, what are the turbo specs?

Gino, How bout a pr. of these 540's ??? Plenty of hatch clearance, don't need any scoops on top. They run on 87 octane, and they made 1350 hp. @ 11 lbs. Totally turnkey. Add a few more lbs to em, put in some 93, and they'll see way over the 1500 mark.

They were run on 110 with I believe about 17-18 lbs, and they did around 1850.
If you're still lookin, call me and I'll hook you up with the guy that has a few pairs of them just sitting waiting for a boat. As a matter of fact, he'll be in Fla this week for the boat show, you can talk to him in person. One pr. are 598's, and I know another pr. are 540's, not sure about the 3rd pr. I know that one pr. already has gone into a 40 Skater up here, but it was'nt till Dec, and lake Michigan was gettin too cold for testing. Another pr. "might" be spoken for to go in a bigger cat, but it's not defineate as we speak.

Yes but he doesn't want to put scoops on his hatches.

Who builds it?

Yes they are. :drink:



Jon

68 mm turbo's, and with the 7 pound spring in for cam testing and R-Tech testing it's making 7 pounds of boost at 1,750 Rpm's :drink:

When we put the the normal 21 pound spring in it is making in the the area of 10 plus....pounds of boost at 1,750 RPM's:eek:

As Earhart would say she's ready to HUNT :ernaehrung004:


Thanks
Jon

Are you hoping to sell the motor package above???

No matter how much power it might make, it looks like poo...:eek:

Have you tested this package in anything other than a 30 Checkmate????:rolleyes:

If it is brought to market, cosmetic's will be brought up to meet the market demand's. This engine has been in use for well over ten years and function was priority over any thing through all the development years.

This is straight off the dyno, and going back in Bill's boat.
Main agenda is to let people know there is a Turbo package that finally works despite the beliefs associated with turbo's.

This one is in Check300's 30' V-Bottom
Earhart has one in his Eliminator Cat

And there are a few more being built for Offshore and I believe you will be impressed with the new packaging.:drink:


Thanks
Jon

Gino,
You have 1500 a side now with those Sterlings. The Vortechs and Prochargers are not the way to go. Joey learned that the hard way with those 1700's. I honestly think you need to go turbine if you want more than 1500 hp out of an combustion engine in a boat.
