Research continues – part 2

After all was assembled i was very much looking forward for testing and ofcourse – finding good results. But…on first tests there was almost NO changes in the logs, feel. Was hard to believe to have nothing after this big effort…

…and to keep it short, after lots of troubleshooting/checking various things and data a found THIS (see pic below) ๐Ÿ™‚ It’s hard to believe i was all the time having this f@$#er in my ‘ass’. This was the answer to my previous assumpsions if i reached my engine’s intake/head’s flow limit. The answer is hell NOooooo ๐Ÿ™‚

Video talks itself what happens when setup stays the same, but you remove back pressure in the ‘ass’ ๐Ÿ™‚

Ok, didn’t have enough courage (and abilities) to build custom intake, so ended up with a compromise ๐Ÿ™‚ Stock mani proved to be somehow ok regarding equal fill-up so the main goal was to free up the channels so the wave would take longer to travel pushing max torque higher up the rev range. It should help to push more air too ( avoiding reaching airflow speed as high as 300mph). Volume of the intake is a little low, but there is no options to make it much bigger, so increased the size of TB a little – now it’s ~70mm. This should a little bit increase virtualย intake volume @WOT…well, i hope so.

The other main improvment should be freshly built Holset HTX40 – can’t wait to test this combination…. ahh still 3 months to wait ๐Ÿ™‚

Summer review

leave a comment »

Hard to believe, that summer season is over, it was sooooo ‘short’… ๐Ÿ˜ฆ

So, what about oldschoolย ? No major mods, just stiffer WG spring, TFSI COP conversion, some logging/testing.

Was impressed that painting IC in black really helps with IAT when idling ( logs showed some 7-10c drop with same conditions). Intake size reduction didn’t show any noticible spool performance.

Biggest improvment was TFSI coils. With the old ones i had .5mm plug gap and sometime felt very little hesitation in high gear on full 2.2bar boost. Now plugs are set @.8mm gap, dwell went down from 2.8 to 1,8ms and boost is smooth as silk ๐Ÿ™‚

The ol’ lady feels veryy fast, but would like to get above 500hp mark. Not sure if i will ‘bite the bullet’ and go ahead as my analysis shows, that i need to custom build intake manifold and that’s not cheap and easy task ๐Ÿ˜ฆ

Low boost Spring

leave a comment »

Spring is going to the end and only now we are gaining some warm temps to enjoy ๐Ÿ™‚

Besides Brembo BB project did some intake ‘tuning’. Used pie cuts to form odd angles for clearing front bar, replaced leaking valve cover gasket and moved Blow off and IAT sensor before TB. Intake piping was reduced from 76mm to 70mm. This clears very well between engine and front. Haven’t loggedย spool yet to see if any difference was made…later ๐Ÿ™‚

BTW, stopping power is godlike – overkill for a 1300kg+ bug ๐Ÿ™‚

Also got BBS RG II forged wheels – only some good rubber left to mount and no any mods this summer!

Brembo ‘project’ is over!

leave a comment »

It’s over! All calipers have been refurbed and fitted with new ‘Zimmermann Sport’ rotors, ‘TRW’ brake pads and ‘ATE blue racing’ fluid. These are ~2kg lighter each than OEM S8 discs. Time for brake in and testing is coming. Stay tuned ๐Ÿ™‚

Stage 3 rear brake upgrade part II

leave a comment »

Been a long way with brake overhauling and finally finish line in front of me! Rear upgrade finished. Took me 2 year to collect parts and make it work. Based on readings and calculations this should be the best balanced brake setup for the Red hawk with it’s F/R weight distribution, master cylinder and brake proportion valve characteristics. Wanted to use EBC redstuff all around, but too expensive and not sure if need for such a huge stopping power. Don’t have so much power after all ๐Ÿ™‚ . These Zimmermann Sport discs will be used with TRW pads, which are OEM quality – should be enough for spirited street/track driving. Handbrake is temporary disabled. Don’t use it at all, so not a problem.ย Can’t wait to finish fronts and test it ๐Ÿ™‚

Rears are now from 280mm -> 312mm.
