Pretty obvious it's Darren. Those bagging the builder are jumping the gun a little I think... if he doesn't know what fuel is being used or how competent the tuner will be it's more than reasonable to keep the static cr low.

I'll illustrate using your example. If you want to compare acceleration then we assume the instantaneous wheel speeds are identical with one producing 320Nm at the crankshaft at 6000rpm and the other making 320Nm at the crankshaft at 1750rpm. To produce 320Nm at 6000rpm engine 1 is making 201kW To produce 320Nm at 1750 rpm engine 2 is making 59kW Lets assume a wheel speed of 1000rpm (this speed is not important). Engine 1 will produce 1919Nm at the wheels Engine 2 will produce 561Nm at the wheels. Given Engine 1 is producing 3.4 times the wheel torque (proportional to the difference in engine power) despite engine torque being identical it's immediately obvious which will accelerate at a greater rate.

To add to the discussion a bit of a comparison. Obvisouly only torque is multiplied with the speed reduction so wheel power = engine power - drivetrain losses (but not considered here). power 400 kW wheel speed 1000 rpm engine speed 6000 rpm engine torque 637 Nm wheel torque 3820 Nm power 300 kW wheel speed 1000 rpm engine speed 4500 rpm engine torque 637 Nm wheel torque 2865 Nm power 400 kW wheel speed 1000 rpm engine speed 4500 rpm engine torque 849 Nm wheel torque 3820 Nm

Zebra, your argument fails. Do the maths, tractive effort at the wheels is directly proportional to engine power, torque is multiplied by the drive ratio together with speed. If we didn't have gearboxes your argument might have some merit.

The journal bearing borg warners are 1k (where did you get 2k from??), so hopefully these come in sub 2k US. The wastegate is in line with the exh flow, rather than at right angles as per normal turbo internal wastegates- what part of that tells you they won't control boost well?

Shipping in the first weeks of December so not long to wait. According to Geoff at Full Race they've been doing a lot of testing which we should see the results for post SEMA.

Such a misleading statement! The relationship between power, torque & speed is fixed, I'll take the one that creates the greatest tractive effort (force at the wheels) over the operating rev range courtesy of that thing that sits behind the motor.

The quiet hint a few pages back didn't work so I'll leave these links here... http://www.motoiq.com/magazine_articles/ar...efr-turbos.aspx And more info http://www.full-race.com/articles/borgwarner-efr-turbos.html

Agreed, the acceleration in your 430odd kw animal was quite special. I need drag radials to put the power down anywhere near as well, so as a street car they don't compare. Then again my gearbox isn't worth 10k haha.

^I had the same problem haha. Plenty of people bagging nangkangs but they are a very soft compound, and with a tall profile offer a lot of grip.

Theres a fair bit of buzz around some new borg warner turbo's due to hit the market soon, ti exh wheels, billet comp wheels, dual bb etc. I'm told the 8374 will be a sweet match to the rb26 for us 35r converts. Why would you use crimp fittings with the teflon hose when there are screw together fittings designed for the job?

Sold.

I have one ATP exhaust housing, T4 twin-scroll footprint, 1.06ar to suit GT35r. New/unused. Cost around 600 delivered from the US. 400ono. PM or email [email protected]

List the full specs mate.

Sean at All Star Garage or Lumpy, but Glenn is a little hard to track down at times. I've used both to tune my sm4 and would use either again without hesitation.

Courtesy the helpful guys at Injectors online, the 11mm caps for indy blue's can be had at any aznew distributor (#ick138). The cap needs to be drilled out however.

Makes sense, thanks. I've emailed injectors online regarding the 11mm caps, see how we go. I grabbed a 14mm rail from mrparts for the others considering machining jap rails. Quality looks on par with the hks rail it's replacing.

Hi Ryan, Excuse my ignorance, but I've got some 1600's to go into an rb26 and obviously the pintle cap is too large. I have a 14mm rail to suit however. Is it as simple as pulling of the pintle caps? I gave em a fair tug but didn't want to damage brand new injectors. With the 11mm caps these injectors will slot straight into the injector port with no other mods - correct?

Check the t4 flange is flat, mine wasn't!

I used the orange stuff to shield a teflon braided oil feed that ran very close to the exhaust manifold (<5mm clearance) and on the turbo drain covering blue rubber hose. After less than 1000k's I've pulled it all apart and the shielding on the drain looks fine however the hose underneath is charred while the orange stuff has dried out and crumbled on the oil feed with the teflon line also blackened. Don't assume this stuff does anything! Hardline and a good air gap are the way to go.

SSR's, black w polished lip inc centrecaps 18 x 9 +16 18 x 10 +11 c/w 225 & 245 rubber New cost for all this was well past 4k. Rims present as new with only a few small marks on the lip but no gutter rash. Will clear gtr brembo's. 3k ono. 0409711428 [email protected] Buyer pays for delivery if interstate. Will deliver Perth metro.

Few pm's asking for a pic - one attached.

I have one HKS fuel rail to suit rb26 for sale. Includes all fittings, mounting bracket and stools (was installed with SARD# 195500-0830, 700's). The rail is unmarked and in as new condition. Can be supplied with either a plug or -6 fitting for the centre port depending on intended use (dual or single feed). $300 delivered. PM or email.

Manifold sold. Exhaust housing still available.
