10k Revs of 2.5L Big Turbo AWD Rabbit Madness!

[gabe@bwperformance]

Any dynos yet of the NA setup?

We are taking it to the dyno before we pull the engine this week. Also the updates have been slow recently because we had 3 other engine builds to finish over the last 2 weeks so the Rabbit has been sitting. Other than that we are now just waiting on some parts from Integrated Engineering.

[tay272]

Sounds good, very interested to see the results.

[thygreyt]

Yo do, by any chance a gotten hold of a set of cams?
What's the na set up as of right now?

[gabe@bwperformance]

Integrated Engineering is working on developing a set of cams but to be honest unless you have a short runner with proper software the cams are not really needed.

ok, but you didnt answer...

whats going to be your NA set up?

will it include cams?

[tay272]

Its posted back on the first page at the very top.

[thygreyt]

ok.. found it.

Indeed they are

[gabe@bwperformance]

Eventually we will find out but I have a hunch that with the stock intake cams are not going to make a huge difference in power.

Well, you sold me my United sri... and I'd like to find out what adding cams would do either way I'll be ready for the cams when Integrated lets them loose.

what power do you hope to put down with the above setup?? 200whp?

[gabe@bwperformance]

210-215whp.

[tay272]

DYNNNOOOSSSSS!!! I wanna see some prehistoric **** haha.

[Anile_eight]

awesome!

[LampyB]

so 210-215whp on e85 right? any idea what the power difference will be when running 93? i don't have access to ethanol out here in MA, it sucks...

~193whp with those said mods on 93oct. When I had the evo header I dyno'd 182whp mods were evo header, my handmade cai, and Unitronic stage2 and hf cat with tt catback

Are you saying you dyno'd 193whp, or are you talking about Taylors car?

[kevin FaKiN spLits]

No Im saying the mods the BW bunny has n/a which were EJ header/exhaust, ported polished head, UM im, on e85 should around the said 210-220whp. On 93oct Im guessing 193whp, my car dyno'd 182 with evo header, hf cat, tt exaust, cai, unitronic stage 2 93oct. If I had a intake manifold and some bigger injectors 205whp on pump gas was realistic. On e85 easily 215-220whp. I dont really know how to add the port and polish into the equation I dont feel it'll give much gains for a low revving motor with stock valve without boost, tho I read some guy that did it claimed 20whp gained from doing to his buddies 2.5, so that Im not sure of

[tay272]

Yeah on 93 octane it should be pretty close to 205. I dont have a header yet but Ill be getting one from EJ when they come out with their revised edition. After I get that installed I wanna hit the dyno again and see what Im up to. This E85 flash may be in the future but not for awhile.

[thygreyt]

dyno yet?

Keep in mind he is in Denver so altitude is a big factor.

Please.....

[gabe@bwperformance]

We will have an NA dyno at some point. Please keep in mind that the car is completely torn down at this point so we can't just wheel it over. Eurotuner magazine has asked us to keep things a little on the down low as they want to be able to show the progress in their magazine so I told them I wouldn't update with pics until something comes out from them however I will tell you that the AWD swap is done, Integrated Engineering has teamed up with us on this project as well and a box full of parts just arrived yesterday, and we just ordered the wheels which are CCW Classics, Race Versions. 18" x 10.5" Black shot peened faces anodized black with the lips anodized red.

[kevin FaKiN spLits]

Glad to see you went with the CCW's. They are so cost effective

Im going to pm you later about the wiring up of the haldex and coding. Have you guys thought of using a Gallardo front differential for the rear which should be full time drive. We have one here we got for 1100$ out of an 06 which doesnt have a wiring harness period, and the r32 rear axles should fit... Underground Racing takes these off the Gallardo's to make them RWD, and sell them off unless the owners want them on... It seems it will bolt up to the rear support of the mkvr rear subframe, you just have to make the brackets.

[gabe@bwperformance]

Wow that looks amazing and it doesn't look like it would be too hard to fab up some brackets to make it fit....

[kevin FaKiN spLits]

Well its light too. I dont think r32 axles will fit, but if the Gallardo axles are the same spline they should work. Its was supposed to be used on an Audi project but I may just take it and play around with it. They are good to 2000whp, as seen by UR!lol

Love the idea

and to make the most of it, you'll need a clutch-type LSD since the rear is all dependent on the right shaft output

Not necessarily. UR makes a LSD for the front diffy, just the $109,000 stage3 kit deletes the front diffy all together. AFAIK only 3 Lambo's have kept the front diffy with the upgraded LSD

I mean on the VAG gearbox

with TBD diff, the front-right wheel could lose all traction (lifted, snow, sand...etc) and no power will got to the rear diff

It doesn't work that way for obvious reasons (it is a vw though so who the ef knows what dumb **** they'll try and pull).

Front wheels are connected to the front diff. T-case is connected to final drive and has no correlation with the front diff mechanism (spiders, lsd clutches, what have u).

You certainly wouldn't 3 of your tires driven by one side of a differential...

Side ?: Does that lambo front diff use a viscious coupler or something of the sort?

[EL_3grab]

T-case is connected to final drive

T-case is connected to the right output from the gearbox

[akauf]

T-case is connected to the right output from the gearbox

nope, it isnt, i assure you. Look at the flaw you pointed out Do u think that sounds like a good design? Right side of the front diff gives power to all 3 wheels and left side to one wheel. All that load on one side of the diff would be poor performing and unreliable to say the least.

Now look at the picture you posted. See where it says hollow shaft? That hollow shaft connects the t-case to the diff cage. Inside of this hollow shaft is the front right axle shaft. The axle shaft passes through this hollow shaft and connects to the right spider (or lsd, or whatever). it is a shaft inside of a shaft and I ASSURE U the right front axle DOES NOT connect to the t-case. The diff cage, thus direct connection to final drive, is how the t-case receives power input.

and I thought I knew my **** , thanks for clearing that up, its actually make alot more sense

[kevin FaKiN spLits]

I dont know about the coupler bs, but the Gallardo is full time awd. This WILL handle 1300ftlbstq before it starts to eat the gearing inside. UR makes custom rings for the differential to handle godly amounts of torque and horsepower. I figured it would have to be run with a full locking front differential because it is not a Haldex unit that kicks on when its told the front wheels are losing traction, so why not Also it would be sweet to have full time awd

It is a pipe dream as of right now, we just have one in our posession and I want to use it in something Who knows maybe over winter I will try to locate a transfer case for the front
