Has anyone had any luck with limiting their boost in each gear or any other method to get traction on the street?What controller are you using and how do you like it?
Thanks

 

I'm using a rheostat, it is infinitely adjustable and it works great once you figure it out. I mounted it on the floor and I control it with my right foot most of the time.

 

Two quick options that come to mind are the boost-by-gear supercharger application from Dallas Performance and also for turbo cars by the Eboost2 with the DP switchplate.

I've been doing alot of reading on this lately to decide how nice of one I want. The HKS EVC VI or something like that (its the expensive one) or the turbo smart seem pretty adjustable as far as being able to adjust to throttle position, rpm, or mph (think you can adjust for 2 of those values as well). The Eboost2 does the same I believe and it's in the shape of a gauge which is prob better for most. Lastly, check out the one by exile. Basically from what I see is that you get into the electronic ones at $300, and the multiple adjustable fancy ones for about $6-700 USD

and a place that sells alot of boost stuff:
http://www.horsepowerfreaks.com/sale...st_Controllers
and I found this one on ebay. it's in the $300 type range. Cool thing about this one is it has a pretty sweet looking gauge, and the controller is hidden. Website is kinda hard to read, so just search for it on ebay and there are some videos and stuff of it. It's an Aussie one so if you have an APS kit it will feel right at home lol

Im using the EBOOST2 like Chris and about to setup the switch plate so I can use that deature.

 

I've heard a lot of good reports on Eboost 2.I like the fact that it's a round gauge.My Blitz controller comes with a ton of options but it's hard to read the screen and mine doesn't seem to be working right.I have the black and white screen which is an older version but the coloured screen is probably easier to read.

Has anyone actually setup their controller to give a certain amount of boost for each gear or have it timed?I'm thinking a 800+ HP car that won't even hook with drag radials.Last year my Nittos worked great in the day with warm pavement but were a problem at night when things cooled down.
Thanks for all the responses

 

The new blitz I-color is pretty fancy. It's expensive tho.

I was running a 305 Nitto Road race tire and was breaking em loose so I'm convinced with anything over 450 hp your right foot is all you got lol.

btw im still mad you sold those heads lol. i'm actually looking at some PRC so it's all good lol. merry x mas.

Ken I am going to buy an expensive boost controller and "try" setting it up in the next month or so and will let you know if it's managable. Car should make around 700hp lets cross our fingers that I'll have enough fuel.

 

Signing up......1st 2nd and top of third are all pretty much worthless for me now.

CMEFLIBI -- Try a drag radial (Nitto). I was at 500/521 and they hooked GREAT on the street. Couldn't do a dump obviously but they weren't willing to just let go either. How far beyond that I couldn't tell you other than an extra 250 RWHP easily overpower them.

 

 

Geez.Now I got the military on my ***Well.I didn't really sell the heads.I told you that as I knew you would buy something betterJust kidding.You got the parts Nick.It'll fly.Get the NLR unit.I'd like to hear how that one works.Keep in touch.
Merry Xmas to you.
Ken

 

I have a turbo LPE car with HRE controller. It is an older model, I have left it off since it there is no traction in 1st, 2nd or on the lower end of 3rd. this is with nitto tires on. Please let me know if you have any success.
thanks
Michael

 

Dont you just need an rpm and speed input for the EBoost ?

Then it can determine which gear you are in from simple maths ( you inpout gear ratios etc ? )


Although TBH...on a high powered turbo car, I feel boost mapped against throttle position would be a far better approach. As thats where the big issue lies. Whether the throttle is half open or full...power delivery tends to be similar when on boost. If you could regain control over power delivery via the throttle like with a n/a or supercharged engine, traction would be more obtainable.


A smaller TB would also help massively in this respect. It baffles me why people insist in fitting huge TB on FI cars ( blow through ), and even more so on turbocharged ones. They dont help, even more so on a street car.

 

Yeah you better watch yourself Eh? Sorry had to throw in a canadian joke. I can pick up some prc's which according to PRC will lower me down to about 9:1 comp ratio which I find hard to believe. I think I will call up one of these guys like ECS who know their stuff and see what they would do. I don't want to pull that engine to replace those pistons.

So what is the NLR unit? I will google it and check it out I suppose.

Merry x-mas ken and all.

 

**warning long post***

Mods, if this is breaking the rules, sorry i was just trying to provide everyone with some popular options that are out there. I put alot of work into this post so please leave it up as I my self would like to reference it.


I'll do a complete review of a few of the popular ones so we could hash out the differences. Please not I didn't put every one on here. I found most of the information off horsepowerfreaks.com under boost controllers:

Never heard of the HRE unit but here is what the HKS one says as far as adjustments for the HKS EVC VI:
Map Correction Mode
Boost pressure can be fine tuned for: Throttle Position, RPM, Vehicle Speed, Throttle Position + RPM, or Throttle Position + Vehicle Speed.

I found the info here:
http://www.hksusa.com/products/more.asp?id=3208

The Blitz I-color seems pretty sweet for the fact that it can take inputs for A/F leaving me with having only two gauges in my car (my meth kit controller displays boost). I'd like to get more info about the blitz gauge on how it works for controlling the power. I guess I need to see some ones who has the sensors and everything hooked up for fuel pressure, boost pressure, egt, and Wideband A/F. That would save from having 4 gauges!

I found the NLR which will even do launch control. This bad boy looks pretty serious for drag racing. There is no way I could see my self putting that thing in my car. It's a $1000 boost controller damnit!

Here is what they have to say:

Multiple operating modes are available to the user: Time Based, Shift Based, and GPS (Gear Position Sensor):

Time Based One to six timed stages are available with this mode of operation. Each stage has an adjustable timer to control the duration. The Ramp Rate (rate at which the pressure is applied) is adjustable from 0 to 100 psi per second. A Ramp Rate setting of 0 does not disable the stage. The target psi will instantly rise at the end of any timed stage with a 0 Ramp Rate setting. The target psi can be increased or decreased over time to achieve the desired Boost Profile.

Shift Based One to six stages are available and are controlled by a shift-input signal. The Ramp Rate for each stage is programmable as well as the Target psi for each stage (gear position). The Ramp Rate settings perform the same functions as in Time Based mode.

GPS Based One to six stages are available and are controlled by a 0-5 volt analog Input signal. This mode is for newer sport bikes or any vehicle that produces a different voltage for each gear position. A switch that produces a different voltage for each position can be used to select different boost profiles (up to six) on vehicles that do not use a Gear Position Sensor system. The Ramp Rate for each stage is programmable as well as the Target psi for each stage (gear position). The Ramp Rate settings perform the same functions as in Time Based Mode. Data logging is NOT available with this mode of operation.

Read on!

-Billet aluminum enclosure and all parts are specified over an extended temperature range.
-Vibration and weather proof.
-System software can be erased and reprogrammed by the factory for future software updates.
-User settings will remain for up to 20 years with no power applied. No back up batteries are needed.
-Factory default RESET available in the options menu to restore controller to state it was out of the box from the factory.
-Launch mode programmable to range of selected MAP sensor.
-Scramble boost to apply an amount of pressure that you program to the gate, thus increasing boost no matter where in the main program you are currently at. Think of it as an emergency boost button (kinda like a shot of nitrous) Remove the signal and it goes back to current target psi. Can be used as a single stage of boost.
-Reduce boost which works the opposite of scramble. It will remove a programmed amount from the current target psi. If you spin stab a button and it will reduce power instantly.
-Delay timer for Activation in Shift Based Mode and First stage of Time based mode may be used as a delay timer.

Multiple operating modes:

-Time Based (up to 6 stages) programmable to ONE one-hundredth of a second.
-Shift Based (up to 6 stages) programmable to ONE one-hundredth of a second.
-GPS (up to 6 gears), self learning, can be used on anything with a voltage output to indicate gear position -- programmable to ONE one-hundredth of a second.
-Programmable Ramp Rate to control the rate at which the pressure is applied. 0 to 100 psi range.
-Dual output channels available or the auxiliary channel may be used for live boost pressure data viewing and data logging. Basically there are 2 controllers in 1 box. You can control multiple waste gates , valves, blow offs on supercharged systems thus giving you boost control.
-Integrated Dual channel data logger with 35 seconds of record for each channel. Graph view of logged data. Logged data will remain until it is erased by user.
-Graph view of programmed settings.
-Display backlight and contrast is user adjustable from the options menu.
-Help screens and setup wizards to help with setup.
-Most inputs can be configured for + 12volt or ground activation.
-All inputs have input protection diodes. All outputs have integrated noise suppression devices to clamp fly back voltage from solenoids.
-Outputs short circuit protected and over current protected(7 amp Maximum)
-Reverse battery protection.

Apex-I
The AVC-R is a digital boost controller with the following functions: RPM based boost and solenoid duty cycle control, Scramble boost, gear based duty corrections, self learning, 2D map trace mode, analog display, real time mode, peak/hold mode, and up to 60 sec data log. The new AVCR's super high-speed processor increases boost response and stabilizes erratic boost curves. The AVC-R also allows the user to control virtually every parmeter of boost controlling whether it is RPM based or gear based. Since many factory turbochargers lose peak boost due to inefficienty factory wastegates, the RPM based duty cycle adjustment can help squeeze out the maximum amount of stable boost pressure.

Sorry for such the long post. I was just trying to put up all the options . I know I missed many, so if someone can help me out and put up the info to the others. This was basically to help everyone make an informed decision so we can see what the best way to controll the power. I bet we could find some good info from the supra guys. They have high wrhp turbo cars???

Btw, here is my meth kit. I has a pretty sweet controller: http://www.labontemotorsports.com/st...how/VCS3G.html
