20 oz bottle will last over 50 passes at the track with plenty to spare...
guys are getting a full race season and then some out of 20 oz

a 5lb bottle is 4x as much.....
I think it is fair to say it will last quite a long time

and you can get it refilled at any paintball shop

He said 5 gallon which i thought was odd capacity unit for a tank but some air compressors are rated in gallons

5-10 lb i thought would be nitrous sized

I fixed the post... meant to say 5lb...
was just talking to somebody else at the same time about another topic, and accidentally said gallon..

Sweet good deal, i like the idea of 2.5-5lb bottles. Should last me the year as little as i drive.

FYI the Boost Leash is very similar to the AMS, just quite a bit cheaper (2 solenoids, only cares about pressure on top of the gate, etc).

x100 the boost leash is very easy to hook up and controls boost VERY well even based on manifold pressure. I drive mine on the street plenty and the boost leash is very easy to use and is very accurate.

What exactly do you want from the controller ? What array of options ?

The two you mention are largely aimed at drag use. Not just big power.

Well I'm still new to all this. But all I want besides the ability to control boost levels is just the ability to quickly change the boost. If I wanted to slow the car down for a street race then turn around and turn it back up that is what I'm looking for.

stevieturbo

So a simple high and low setting ?

Maybe 2, 3, 4 settings ? ie static boost levels.

Not boost vs speed, boost vs rpm, boost vs gear etc ? These latter options requiring more expensive controllers.

If all you wanted was 2 easy boost levels, then there are plenty of options.

Turbosmarts E-Boost street is a simple one, and circa $300 ( there are of course other sellers and prices, it just appeared on google. Some cheaper than $300 on Amazon )

Turbosmarts E-Boost 2 is popular and bloody good. More expensive, but it will allow you 4 different boost settings.

Seems to be around $450 on Amazon.

The Boost Leash is not just for racecars. It works very good for streetcars too. Easy to use.

stevieturbo

Can it do the above things I mentioned though, which are very very useful on a very powerful street car ?

ie true boost vs gear, boost vs speed, boost vs rpm. Or any one or combination of those ?

Simply targeting and holding a single boost pressure per setting is pretty easy for almost any controller to do and there are a myriad of controllers out there that can do that.

It will do any type of boost control strategy you can think of. Speed, time, time by gear, engine rpm, turboshaft speed, drive shaft speed, tps, gps or a combination of every single one of them.

Offered in a pro platform with full datalogging and gmeter and a base unit which can be updated to a pro at any time.

Lots of street cars are using it and absolutely love it.

All of our controllers can be used with manifold pressure as the supply source.

From a simplicity point of view though....yes boost by mph etc will be easy.

But how does your unit determine gear ? Looking at your site, looks like you still want some sort of mechanical switches etc fitted in order to provide a voltage to your control unit ?


Seeing as it has the ability to accept a speed signal...and engine rpm, driveshaft rpm, whatever

Why not include in the software the ability to determine gear from the information ? Or easier still for a lot of modern cars, if you could pick up the data from OBD sources.

Would really make for an easy plug n play install

NLR

As with any ecu you need to send a voltage per gear for a really easy set up, which we can do. It can accept a analog input .
Doesn't matter if its a motec , pectel, marelli , bosch or whatever. Even if you create a math channel in the ecu to determine gear it is still based on a speed input for information in order to do that. If its something that's demanded we will do it.
We have can bus capability and once we have all the protocols we need if the stock OBD source can send info telling what gear its in then its no problem.

Run air and then not worry about c02. Easy tire pressure adjustments at the track too

stevieturbo

As with any ecu ?? ermm...no you dont.

You send the ecu vehicle speed, either via the VSS sender or via actual wheel speeds. That's a given anyway.
The ecu already has rpm...and you tell it the gearing for each gear.

Then it calculates gear. It doesnt get much easier and that is how most ecu's will do it. Having to add some sort of setup that outputs a voltage in order to determine gear is probably the most awkward way you could achieve it. Just how would you do that on a 6 sped manual for example ?

The only transmissions that routinely send out a voltage per gear are dedicated sequential gearboxes. Not even sure if automatics do it ?

I'm not trying to knock the product, I just hate the fact these companies selling boost controllers claim things, when the reality of actually making them happen is far from those claims, or at best quite difficult.

Ecm always knows what gear and converter lockup status is on gm electronic autos

NLR

I said for a really easy set up. I didn't say for a specific car.
Well Im lucky because we have sequential boxes with gear position sensors that output a voltage per gear on most of the stuff we deal with that would want boost by gear.
I understand how to get gear from engine rpm , transmission gearing, and speed input its pretty basic math. We did not put the math in the ecu because frankly most would want just a speed based control set up rather than gear.

There is nothing difficult with a gear based program. If there is a demand Ill do it .

Most of the queries Ive seen on the forums from people with powerful manual cars ( not specific drag use ), that is the main query they ask about.
