S15 Splitfires (NEW), Gfb Bov S15, Mars LED taillights (Dmax style)

28 December 2017 - 02:38 PM

Fresh S15 Splitfires, never installed or used. Can ship anywhere in Aus. $400

GFB Mach 2 adjustable stock location BOV for S15. Only used for a few thousand kms, still very good condition. Can ship anywhere in Aus. $130

Mars S15 LED taillights, no globes included. Working when taken off car, pretty good condition. Just too pimp for me. $170, ceebs shipping unless someone twists my arm. Can meet up near Knox City or Dandenong depending on time of day. Melb Western subs possible if you're not in a huge rush.

Any questions just PM

Borgwarner Electric Superchargers

Anyone reckon something like this could be snuck into a Silvia engine bay to squeeze more street-friendly bottom end out of the SR or is it just another pipe dream? Guessing it would at least be more compact than a belt-driven option.


Comment from their facebook post:

"The 48V eBooster cannot be used with just a 12V battery, however we do intend to develop and release (in the future) a specific 12V version for low-voltage applications. The eBooster couldn’t be a suitable turbocharger replacement in most instances since it makes a fairly low pressure ratio and runs out of flow capacity midway through the engine speed range. However, there may be some niche applications where these constraints are OK. Generally speaking, the eBooster and the turbocharger are intended to work together in tandem with the eBooster taking care of low speed operation and transients and the turbocharger taking over the primary duty once the engine has achieved the target boost pressure, including higher engine speeds. Hope that helps answer your question."

Effects of custom dump pipes larger than 3"

19 August 2016 - 02:50 PM

So I've been searching around for ages and haven't been able to find much info about dump pipes larger than 3 inches on a single turbo application (T2/stock mani on Sr in this case, for arguments' sake).

My inspiration for this question is from a facebook post by a guy who does lots of fab for JZs (post is at: https://m.facebook.c...655171301421342 ) His results going from 3 to 4 to 6.5 inch show the boost delivery getting proportionally earlier in the rev range.

There's heaps about split vs. bellmouth but I'm curious to know if anyone has ever seen any solid gains below the curve with an enlarged 4/5/whatever inch dump pipe on a single turbo application where say the dump ID expands after the flange where possible - similar to the dumps in the facebook post. I know that post is about twin-turbo and with a completely different style dump but his dyno results plague me with the question of "what if?"...
I would gladly fork out money for such a simple exhaust mod that gives significantly more response without having to commit to a high-mounted twin-scroll setup.

So, have I missed this info somewhere or does it just never come up because it is known to be completely useless?
