**OMG-VRUS TB shows "wicked" Dyno Results**

Well - Im go'in nuts wanting to see the graph's
Chris @ C2Designs dynoe'd the car today w/VRUS 80mm TB installed - Results are thru the roof!!
On 4 pulls Chris said the best #'s as follows:

528 RWHp // 595 WRTq (not on the same pull)

Of course we ?'d why such a drastic improvement? I'll list as follows:

-Pre TB -------- 80mm TB
457/519 ------- 528/595
95 degrees ---- 70 degrees
A/F "Pig Rich" -- A/F near Perfect

He stated that the Dyno was the Dynojet "Large wheel" for bigger
powered cars and this machine although maybe a "tad" high,..he does
say the car runs like it is making this huge power!

Chris @ C2Designs has repeatedly said now that it will "leave tracks"
from 50-60 mph. -No Sh**! Says the car is "ridiculously fast"
and he feels the car is "dialed in" about perfect!
I'll post Dyno graphs as soon as I get the file!

Kudos to you Victor (VRUS)-GREAT Mod!! and especially Chris @C2Designs in Tampa!!
I fly up to Tampa next Monday to pick up the car & drive home. Full report to follow!!

HeHe, I'm just like you.

Get ready to defend the dynos. Also, get to the track ASAP.

Believe it or not I just got back from a trip to the track and for the second consecutive time they closed the track at the last minute.

Congrats Ken!!! That's great man! These 80mm TB's definitely are a great mod that produce huge power.... power you can definitely feel! Hands down the best $2,500 mod you can do (well at least for us K2 guys).

Ken,

I do not trust my butt dyno or for that matter, any dyno. I think trap speeds tell the real story when you're talking performance modifications.

But to answer your question..........Yes, I feel a significant difference. As a matter of fact, my ESP was engaging tonight when I would stomp the throttle at 75mph.

Ken been away from the TB thread - can quickly you tell us your set up before the TB was added - are you stock, K2 or what ?

I'd love to see what the TB alone did - anyone have that?

Thanks
Phil

That's awesome Ken!! I am so happy your car is nice and healthy!

JakPro1 was showing 559rwhp with his TB & SLR cam combo.. and he was a K2 car before also.. Your car with 528rwhp is right inline.. The SLR cams we guestimated were good for 20rwhp - 25rwhp which is close to what the gap is.

Have fun & enjoy that monster!!

P.S-> My car went super lean when I finished with the TB but I had a good A/F to start.. Your car with a pig rich A/F, the 80mm TB was just what the doctor ordered to "dial it in" as Chris said..

It's the VRP special sauce that makes the extra power.. That and I install an in-line mini-flux capacitor to increase the voltage signals on the TB... Oh yeah.. and the special porting using those carbide-diamond-titanium special bits that were found on the surface of the moon.. Those are really hard to come by.. but I have 2 of them..

Nice gains! This TB really helps out with cars that are already modded - its like fixing a deviated septum! Now you're breathing nice and easy. Anyone get a dyno on a stock E55 with the TB yet?

Yes...but be aware the air temperature and A/Fuel ratio are major contributors
to the VRUS TB showing such Huge difference in power!

I'm normally not a doubter, but there is no way a TB will give 71 rwhp..... tuning could make quite a difference though....

are the pulls SAE corrected? should that take care of the temp difference?

Ken... let's try it out at Moroso... finally some decent weather here....

Fikse...To a small degree, my initial feelings also.......but
My 457Hp was Pig Rich in 95 degree weather and uncorrected
The A/F ratio was close to 10:1 and I never got the ECU re-programmed f/Klemmann before the TB install. When I study before/after..a few thoughts

1.) 25 degrees cooler(today) on FI motors is worth 20-25hp alone!
2.) A/F going f/10:1 to 12:1 is probably worth another 15-20Hp
3.) That means the TB realistically is giving me 30'ish Hp(that's believable!)

I knew going in I would see a Huge jump because my new K2 w/o being re-programmed was showing only modest gains.
Most on the forum are 470hp - 500hp "tuned" --w/K2...I was @457 "untuned"

Yes... the track will be the proof - I'll be out there the first chance I get.
I'm sure there are a few sceptics...but the law of engine physics does
suggest this to be at least possible. I'll post graphs as soon as I have them.

Ken,

Great explanation and I agree 100%.. Makes perfect sense..

The next restriction in line now is the airbox and tubes... Gee.. I wonder what is coming off the assembly line soon to take care of that problem.. LOL..

Thats what Im thinking. I think a K1 or K2 car will show greater gains than stock.

Your right...but my K2 ONLY netted 46rwhp
Please understand......my K2 was not tuned but the TB, 25 degrees cooler, & VRUS 80mm TB worked wonders for bringing the A/F ratio to almost perfect!!

If I would have tuned my K2 originally, & done a dyno pull in 70 degrees.....
the REAL Hp # would have probably been more like 490-500Hp
The TB did not give me 71 HP......................but everything
else coming together at the same time netted me a TOTAL of 71Hp.

Please see my explanation a few threads above this one.

My tuned K2 w/VRUS TB(K3VRP) ..... is now in line with everyone else!

Oh no way?? I thought you leaned out the A/F yourself while the car was on the dyno. The TB alone brought you down in richness? Thats awesome. Does that mean you were running that rich the whole time with K2? I would think that by stage 2 Klee would make some adjustments to your A/F to even it out... Very impressive gains nevertheless. I need one of these TBs.

That's correct!! When I put on my K2, it was while the world cup going on, and everyone was tied up do'in the "German" thing while ECU files set on a computer somewhere. One thing led to another...I did not want to wait....so I went ahead and picked up my car w/out it being properly tuned. The extra air from the new 80mm TB brought everything in-line where it should be. I should have the dyno graphs in my hand this morning to see everything exact!!

With that much power you should have no trouble pulling 125MPH traps which would be very impressive....
