Ive heard so much good and bad with porting. Ill give the cams a shot i just talked to Jared and hes going to send me the specs on the BR 280/280 cams

 

The way around 'good and bad' with porting is to demand a before/after flowbench sheet for YOUR head from the porter of your choice. That leaves little to speculation, and head porting at this power level can be worth a substantial power increase (think Honda B-series numbers).

As for the BR '280/280' cams, I assume you are referring to the new cams? Be certain.

 

Is this a Precision Turbo, T67 Turbo with p-trim & t-4 housing? or, is it the same turbo, with a t3 housing machined to fit the p-trim wheel? I think this combination is what is called the gt37r.

 

yea me too... too bad we don't have it here in jersey yet... i wonder why

awesome numbers, and to think they could be improved with some better cams is even better!

 

Flex Fuel make me happy in pants. 9,000 RPM even better congrats.

 

nice numbers.

 

so if I wanted to run E85 in my car for daily driving and tune for a little better power....not lookin for big power...just cheaper mor epwoerful gas.....what do i need to do..??

 

You gotta love a build 2.0, held power to 9k. nice

 

ifarted2 would you happen to know what the duty cycles were at??

 

In doing my research for a higher RPM DSM/EVO camshaft, I have not come across a cam with more effective duration than the BC 280s. I am curious to better understand your judgement of this cam set vs the other cams that are available from the Japanese manufacturers?

For example, to my knowledge there is no way to compare durations of cam A measured at .050 vs cam B at 1mm. So you can't guess that a Jun 272 that has an effective duration of 235* at 1mm likely has more RPM potential than a BC 280 which 218* at .050" My current understanding is that the only way to compare would be to have each cam set and measure them for yourself.

Is someone aware of a domestic grind with more RPM potential than the BC280s?

 

We have quite a bit of meth in there so the DC were at 71% peak.

Plans for the car in order are

-Boost leak check to 40psi
-cam gears set like Ted said than play with them some on the Dyno
-C16 tune with and with out meth
-Cams

If the head ever needs to come off than port work to.

 

Paul boost is not allways the key We could have done 40psi if we wanted but no need if it does not make any more power. When we went from 35-37psi and only picked up 7hp there is no reason to push it harder on boost. We picked up almost 30hp going from 33-35psi.

The turbo is a T4 P trim exhaust. Talking with AMS it looks like we should get over 700hp.

 

Are you guys planning to tune on just straight e85?

 

TedB dam you now ya got us all thinking up here about more power
yeah i talked to Jared and just waiting for a pm from him on spec on there new cams. I just drove 350miles up to Seattle and i did a bunch of pulls to 9000rpm plus and i tell you what it scared the **** out of me in 4th gear at 9k lol

 

Yes I would like to see what it can do straight E85.
