I have had my RB's for over two years and I just ordered the TFT intake kit. Looking forward to hitting the drag strip this spring!

You're going to love it

This is also a good point, BOOST is a common language and SHOULD ALWAYS be monitored. He was excited to get results based on how the car performed that the proper equipment was yet put into place, and decided the reward was worth the unknown.

But to think 48% WGDC is the ragged edge is sorely mistaken, there is no way this thing was making large boost at that amount of WGDC. On the other hand 68-70% (like the competitive car) or more, that is getting up towards the extreme max effective WGDC. This RB car has some ways to go before getting there.

Thanks,
Rob

Beats me man 600 whp was only around the corner come to think of it! To make things worse someone on this forum is selling his pair of RB's from a 1M and those fit my car bro!

Would have at least kept me more than entertained least till the extreme hybrids were being built!

335xi unheard of these part of the world unfortunately

Shipping container.

GTR killer haha those are some strong words. I'd be willing to bet a stock turbo gtr FBO+100% e85 would take it down. Just my opinion and that's stock turbos

Hes pulling off doing a 1.70ish 60' so thats GTR territory, and now hes drivable 100 awhp more.

I call his the GTR 335xi ...... lol

[WedgePerformance]

Can't wait to see the numbers.

What clutch is in the xi?

Several packs of them, it's an AT

Congrats to RB Turbos and Wedge/BQ tuning. Nice torque down low.

[Wes335XI]

Any idea if this kit is out for production? Anyone know the cost? This looks really promising.

Yes the TFT kit is being produced at this time. You can google "TFT N54" and find results.

Thanks,

Do you have a datazap link over this pull? How much PSI were you running ?

Per Post #1:
Datapoints-

RB Car (Blue lines)
E92 XI/AWD Automatic Transmission in 4th gear. Independent results.
RB Standard Turbos with TFT inlets, Billet 15T Compressor, MHI 12 blade clipped turbine, stock charge pipe
Boost- Unknown (entire pass slightly below 50% WGDC)
Fueling/Tuning- OEM HPFP with inline LPFP. E60. Fueling insufficient at this time and to be addressed at a later date. Wedge/BQ Tuning.

Any other questions let us know, as some of the boost curve was over the DME's limits SOME was not (towards redline) I do believe. I will see if we can dig up what is known though, I am curious as well.

Thanks,
Rob

Is the hot side charge pipe really necessary or can we get away with just the intakes? I'm more interested in making power...cheers

Unknown, as the DJ external boost logger was not working.

However here is some food for thoughts . Within the TMAP sensor range limits he put down 528 awhp / 555 awtq same day on 21psi tappering to 18.5 psi @ 6700 rpms with a " sub 40% WGDC "

Now we continued to rais boost just about "sub 50% WGDC" coming to the OP record. This should give you general idea of how much boost was running with a 10% increase of wgdc.

Without trying. My buddy has 750hp gtr with stock turbos, tune and E85

Agree with you 100% that we are not talking about big boost in this pass.

But for the sake of conversation was there any point in the record pulls powerband that we were within the TMAP sensor range limits? Or all over? I was thinking I saw that toward redline it came well back under limits.

This record car did have 100% stock hot side charge pipes.

In our opinion the hot side charge pipes will not amount to much due to the fact that the compressor housing itself has its limits. Not that it still isn't a good mod to extract utmost efficiency, as there are some design deficiencies in the OEM hot side charge pipe… but likely will not be accountable for big power gains. Nothing to the level of the inlets...

Thanks,
Rob

Bro, I totally missed this for some reason....lol. Correct, boost came back within the TMAP sensor range after 6k RPMs

Black out occured just after 3500 RPMs and returned back on to the TMAP sensor limit range just after 6000 RPMs

So the 10% increase of wgdc cooborates to 23 PSI and started to tapper off to 20 PSI just before redline.

When I saw the logs I was looking on my phone and didnt look at the entire log to the end.....lol, thanks for pointing that out. This is the same boost I ran on Ken's(Wedge) car on stock turbos but at double the wgdc

Thanks for the insight, it is appreciated. So just for the sake of being as fair as possible, we certainly were no more than 25psi-20psi taper through redline.

What this means is that we were actually making MORE power than the competition at around 4psi LESS (and 20% WGDC LESS) through the entire power band. Hope this additional information helps.

Thanks,
