Excelerate Performance - tial 770 build!

[XLR8 Craig]

B5 S4 owner's are always upgrading and this car is no different. Customer came in with his rs6 powered car looking for more kick and tial 770's
were exactly that. Along with that will be a motor build and many existing plus added modifications will be going into this car to make it run like new.
Below is just a short list of what is on the car and what is to come! We will be updating as the build moves forward.

Currently in the car

• O.E rs6 turbos
• ASP stage 3 fueling
• 034 3.5 inch single turbo back
• 034 motor mounts
• Apikol transmition mounts
• Front mount inter cooler
• APR's Bi-Pipe

To come

• TiAL 770's
• Silly Rabbit Motorsports manifold's
• Clutch Master's 850 twin disk
• Ferrea valve upgrade
• EPL's fueling / tuning
• Custom in house Tial 770 down pipes
• Built BEl engine with I.E rods and Mahle Motor sports pistons
• Full rebuilt transmission from JHM

Coo build.

But why do you say "Fully built JHM transmission" when its just a stock rebuilt trans? Just seems misleading unless you are doing an aftermarket gear-set or dog engagement.

Changed the wording around as it isn't to mislead anyone. The Transmission is getting the full rebuild with upgraded collars.

Just FYI its Mahle Motorsport....not Molly.

What's the final displacement of the motor going to be?

No cams?

EDIT: Thought this was a shop car build... now it makes more sense.

[MikeyB3]

!! Whoo hoo! Cant wait to see! Are you going to try and talk Tony into tuning it?

customer car and they are staying 2.7 and o.e cams as of the moment.

yes as far as i know European Performance Labs will be doing the magic on the dyno with this car!

[Mark00s4]

cool look forward to updates.

[zatch_303]

sweet! definitely going to be following this.

[XLR8 Craig]

This is one of two we are currently building right now. We will start a separate thread to cover the build process of the other one at some point. Thanks all for following. This car should be quite fun when its done. Good power without going overboard. :) Reliability is a key aspect here.

In westchester county NY here. Looking forward to updates. E

Are the pistons the mahle powerpak or powerpak plus? If they are just powerpak there is no reason to change the pistons while staying 2.7 since the OEM pistons are a stronger alloy than the powerpak pistons.

Even with all the horror stories that have been popping up about them?

I don't see the reason for changing pistons at all for 770's to be honest. New rings, with slightly more gap maybe if the person is really gonna run the crap out of the turbos. But it doesn't sounds like they will since they're not even doing cams, heads or any thing else like that.

Build it once and do it right is the mentality here. It is easy to swap the heads after the fact but still, doing it now would be highly valuable to the customer. The build is not 100% set it stone yet either, things can change. The black car we are building changed every two months, so I would like to avoid those play by play changes by sticking to a build schedule. This should be finalized this week. But we are getting the jump by getting the motor out, making some mock ups so we can start fabricating the downpipes before any major work does on. This way when the motor is together it can drop right in.

Thanks,

Greg

Aren't stock heads a restriction for those big turbos?

Many report that the ~550hp barrier can not be passed with stock heads.

General consensus, yes. Build sheet should be finalized in the next few days after fabrication of the downpipes is completed. I think there are some small things on the list that can be left off to make room for the 2.8 heads and cams. As always this thread will be updaetd with progress as we move forward.

[XLR8 Craig]

Little bit of an update with this project.





Good things to come.

Thanks,

Alex.

[james 408]

Looks pretty sweet guys.

Stock head build over 550whp.

[XLR8 Craig]

Just another little update for everyone.

The car will now be getting 2.8 cams and heads.

Thanks,

Alex.

[Mark00s4]

very cool build. im in the slow progess of building a similar build just with 605.2. im in for updates.
can i ask you a few questions about what machining work you did.
what size pistons did you go with? were torque plates used?
what kind of main and heads bolts are you running? oem or studs?

scott mackey made 715hp with 2.7 heads.

[tasinb5s4]

Is that costumer interested to sell his rs6 turbos ? Turbos only

[oppositelock]

He says heads have mild porting.

Not quite sure I will check with the customer.

Thanks,

Would have made more with 2.8 heads...

the ports on the 2.7 heads are tiny

that wasnt the point though.. someone said the limit of the 2.7 head was 550hp+/-

Ah you're right not sure how I missed that.... and obviously wrong.

[armageddon-]

I made a question not a statement ...but whatever you say

[james 408]

Don't stress it, nobody's throwing rocks.
As stated: it's not a hard limit like 550hp (depending on the turbo/motor selection). It merely shifts the torque curve to the right -- increasing horsepower, but reducing turbo spool. Same as larger manifolds. Both are restrictions of sorts at higher rpms on larger turbos. Some elect to leave some restriction there to widen the power-band. Although it depends on the specifics of the build (including max rpm and turbo size) and the application as to what best suits your needs.
