**NEW RECORD** most powerful 9b car ??

Wow no exhaust either.. impressive! How much did you change timing?

I have a PitRoad M 4" Titanium Cat back, however that is fitted too a 2.5" test pipe lol. The Down pipe is stock as are the pre cats, although the JDM pre cats and down pipe are empty they are not as free flowing as pre cat eliminators.


I am running around 20-22* at 4000rpm (peak torque) and climbing to 28-30* at peak HP/rpm

Got a pic showing how low the u coupler puts the post IC pipe?

Thanks for sharing timing numbers.

Hi jeff,

I'm not sure I understand your question.

The U bend is pre IC, it runs along the front of the car in 63mm black silicon where it's fitted to a 90* bend which then meets up with a Y pipe before joining the two turbo hot sides.

The cold side comes straight off the cooler with a 90* bend and straight up to the throttle body.

My theory behind this routing was A, the hot side wanted to be longer to allow as much heat to dissipate before going through cooler.

B, the cold side needed to be as short and direct as possible.

C, I wanted as little pipe work as possible in the heat soaked engine bay.

My setup MUST work as it is the cheapest eBay core I could find yet with some ducting and custom pipes I see a max of 15c above ambient at the throttle even when pushing the 9b's way into hot as hell air zone lol

How far below the bumper is the pre IC pipe? From the pics it looks like none. I really like no plumbing around the timing belt area. It also has the pipes routed away from the turbo's hotsides. I love it!!! Just really wondering about ground clearance.

I misinterpreted which one was pre and which one was post IC. Your explanation got me back on track. Thanks.

The pre piping sit INSIDE the bumper skin so nothing protrudes at all. The nice thing is also the car looks nice and stock without loosing fogs and no visible pipes hanging out the front bumper.

Also with the engine by routing as is I an replace spark plugs in 20min with only the throttle pipe needing removing.

The front turbo hot pipe to the y pipe is actually the stock rubber one that would go to the stock side mount normally and the rear one is another stock y pipe hose used connected to the upper custom section.

If you need any more pics let me know

Here is a post made by Andre proving what I've been saying
all along.

Ok, I have watched this thread revolve around uk FWHP vs us AWHP, trap speed and weight (pretty accurate in my book), US power producing similar speeds to UK power etc.

If trap speed and weight are taken to be a pretty difficult method to create inflated power figures, here are some examples and how they work out using this online calculator

Matt M 168.5 mph 2920 lbs = 1090 hp, dyno'd 1093 hp
Me 158.48 mph 3256 lbs with a slipping clutch = 1011 hp dyno'd 1057 FWHP
Me 147 mph 3568 lbs = 884 hp dyno'd at the start of the season at 832 FWHP
Me 143 mph 3620 lbs = 826 hp dyno'd a couple of weeks before at 832 FWHP as above
Mikes95rt 101.35 mph 3390 lbs = 275 hp dyno'd 275 AWHP 325 crank
Mikes95rt 112 mph 3390 lbs = 371.7 hp dyno'd 372 AWHP 435 crank

I think this kind of proves the point Elton has been making all along that for whatever reason (and I don't really care what it is) the UK FWHP is pretty much equivalent to US AWHP. In fact, the biggest variance is one of my runs where the car was making around 50 hp MORE at the track than it had dyno'd earlier in the year. Atmospheric differences between dyno session and track session? I don't know but it is interesting that the UK dyno number was less not more after claims of inflating hp numbers by reporting as FWHP has been suggested earlier.

By the way, my dyno numbers were produced on the same dyno as Elton's by the same dyno operator.

Anyone care to add their KNOWN car weight for a given trap and dyno plot?

André

Hopefully I can now finally enjoy my record without needing to justify it anymore

Ps, I'm going back soon to try make more as I know there was around 5-8whp more when we stopped last time. I had miss fires in high boost and ran out if fuel correction to lean off any more than 10.5 afr at the top. Both issues have now been addressed

I have just drawn on this pic to show where IC pipe runs. No cutting at all required to bumper and stock undertrays fit back on fine.

From what I'm gathering the pipe literally sits or hides in between the bottom of the bumper? Pretty good idea, I would never have thought of that.

Yup, in between the bottom if the IC and under trays.

Here are some pics of my spare bumper skin showing where the 63mm pipe would fit
