hey guys i hope this is the right spot to post this, im a newbie on this forum.

PLEASE NOTE THIS IS FOR MY DRIFT CAR (A31 Cefiro, Rb20) I DONT HAVE A CAT SO DONT SAY OH ITLL SCREW UR CAT OR ANYTHING LIKE THAT.

also, please no useless posts, i just wanna know wether to get 1 or not becoz the group buy seems cheap and ive always been thinking about getting 1, now the chance has come.

Just wondering, bee r rev limiters, i understand they are good on the inside motor side of it. what about when ur exhaust is combusting fuel, is it treating the turbo ok? is there any down falls to getting one? im not doing it for wank factor, if u guys all say theres no use besides wank, then i wont bother. but i want a reliable drift car.

I bought one these for the purpose of flat shifting, I have a micro-switch hooked up to the clutch pedal and everything. When I try to flat shift, the gears won't slot in, I've tried doing it at different rpm's but still the same result. If you can't do this I don't see the purpose of them. Maybe this is just my car, maybe its just the way I have set it up but IMO its not worth money. You'd be better putting your money aside for something useful ie. water injection, lots of toluene.

Another thing I've noticed when I normally shift with the micro-switch engaged the knock the level jumps by 8, and this is with a very conservative tune only running on 8psi until I finish the rest of the mods. So if you put this on a motor already on the limit that gets flogged around a drift track I can see the knock value jumping dramatically. And your motor will be more than likely pinging it's tits off ending in certain destruction.

the benefit of the Bee*R over the standard limiter is that it cuts fuel rather than ignition so theres no leaning out in the cylender, but if it detonates in the exhaust housing of the turbo this could cause some problems over time, but it should detonate in there coz its cuts ignition, not to say it cant happen but in theory i guess it shouldnt!

there is no real benefit to them apart from the flames. fuel cut rev limit is not bad, and your engine does not lean out. the rev limit cuts fuel completely so there is no combustion at all in that cylinder. the only positive the bee-r limiter will give you is some pretty flames and some banging.

now its really early in the morning, and ive had too much coffee... but i thought the bee r limiters cut ignition, not fuel.. hence the overfueling and causing the flames.. as a mechanic, i can say that an engine doing 9000rpm, then having its fuel cut is a recipe for detonation.

the limiter is designed for launches.. so you can set it at your desired launch rpm, hold the throttle wide open and it will hold it at that rpm so all you have to do is hold it flat and dump the clutch. im pretty sure you can set it to a certain rpm to act as a rev limiter, aslong as its before the standard rev limit.

just buy it, who cares, id pay $200 to pop a flame.. its heaps fun.. i could do it in my garage all night long! while your at it, get an ecu that can control anti lag and get that set up.. wake every bastard up at 2 in the morning in your street.

just remember, if theres a reason, no matter how small it is, its worth it.

cheers

My car is running it at the moment.. and its one of the best mods I have! It just sounds so aggressive in real life, you tube

videos dont do it justice....

If i banged the rev limiter ready to launch next to a VL or something at a set of lights, i believe hed either take his seatbelt off

open the door and run or jst turn into the nearest driveway so that he doesn't bother...

However, im sure its good for the engine but i just want some clarification on what its like for the turbo... im running a Garret GT 28-76R...

ball bearing.

Thanks

      Duncan's V37.......race car?

      By The Bogan · Posted

      Can you log IAT? Whilst WTA coolers have their place, doing any sort of sustained run is not one of them There are fixes that slow down the heat soak, like ice boxes, which don't last that long, and interchillers, which are fairly expensive, up grades to the WTA cooling radiator, which may require a bigger pump, and upgrades to the reservoir size,  and upgrades to the cooling fans, but, it all still heat soaks, and takes ages to come down in hot weather  For a turbo, that isn't locked into WTA like my PD blower is, can you not possibly swap to a nice air to air intercooler????, it would be better for sustained runs then, and have alot less things that could go wrong in my opinion

      So, the other thing I've sorted is a baseline dyno run up at Unigroup's new location. The auto trans was a little unco-operative by both shifting down when the throttle was floored on the dyno (so Mark had to ramp it up more slowly than in a manual) and also by shifting up at 6,000 even in sports mode instead of the indicated redline of 7,000 Still, on a hot day it made 240rwkw at 16psi which seems about right for 300kw (400hp) through an auto at the wheels.  The shape of the curve is not quite right because it was not full throttle to about 4,500 to stop it kicking down, but until I can get a tune on the auto trans control this was the best we could do.....full boost will be well below 5,000 once that is sorted, I'll get some data logs when I can to confirm For comparison, the R32 made 255 at 12psi (at 4,500) on the same dyno with tune, n1 turbos, cam gears, big exhaust but otherwise all standard so the v37 is likely a little better out of the box. One thing that is very clear is that the standard water to air intercoolers are not up to sustained use at full throttle in warm ambient temps. After about 5 runs (so only a few minutes full throttle), it was pulling boost and timing and dropping 10-15% power. Unfortunately I didn't get that printout and the Unigroup guys are away at the moment, will try and get hold of it on their return. So, looks like a healthy engine to start modifying and the only real area of concern is the w2a heat exchangers which the aftermarket has plenty of solutions for

      I maintain it actually looked really nice in person. So much so that I thought "No, this is illegal" but there it was, clear as day. I think we can easily call the wing and wheels/height to be transformative. Not saying it's better than the GR Whatever, or the 86, or the WRX STI or anything of that sort (the internet says it all bolts up so you can buy best of all worlds?) but it's still at least a thing and not nearly AS bad as people say.

      That's less offensive than the previous gen.....except for all that ugly black tupperware around the edges. Blerck!

      I leant out the window recently and took a picture of this new WRX. It looked real damn fine in person. It's faster around a track (stock) than a (stock) GR Yaris. It's much more practical despite being heavier. It's significantly cheaper. This gen tunes really well, much better than others. .... I think they're probably a lot better than people expect.
