Boost logic uprated box

There is a limit to what they will handle though.

 

You need to speak to boost logic about that and what turbo you are using etc and they will advise if it will hold the power etc.

 

There was a problem before with the front clutch piston going but that has now been fixed.

8,000+ miles, 60+ drag strip launches, track days, traffic jams, a 500+ hp engine, 10 second 1/4's, two oil coollers, 1 oil change and still going strong!!

 

Yeah it's a great box, BL have done numerous 7-8sec passes with one...it's a good box, you've nothing to fear by getting one.

 

Terry S is the man for BL kit.

Called them yesterday say it will handle 850 rwhp aslong as its taken care of not ragged through gears launched properly etc

That's intresting because when i was reading up on if the BL or SP box was better they both wouldn't give a figure of what it would hold. Seems the boxes can hold great power, but can also break on low power too. I belive it's better odd's that they WILL hold the power, but it's a gamble.

PM sent :)

I was looking at the SP Stage 3 not too long ago, I was impressed by their willingness to actually say what was changed rather than just saying "look, it's better, give us money"...

I'm sure the BL is spot on and people seem to have great success with it, it really seems like you have to pamper the modded standard stuff though once the power levels go up, they might be OK for some hard runs on the strip but has anyone used one on in anger on track?

 

I don't really want to go manual, the TH400 isn't very good on a road car apparently and the uprated standard ones are prone to random failure... tricky isn't it.
