stroker kit?

[Installshield 2]

also forgot to mention...what Gen1 talked about comes into play when picking a compression ratio...generally, as long as adequate means of tuning are available, a higher compression ratio can be run with a lower rod ratio engine...mostly because of the small amounts of TDC dwell time...with less dwell time, and a very high compression ratio; you are squeezing a mixture of gasoline and air very tightly...igniting it...and then sitting on it; not allowing the piston to retreat back down the cylinder...some really funky thermodynamics come into play when you do that...and eventually the engine owner gets s*** thrown at him...(mostly the head bolts get stretched, or the head gasket gives in...or both)

But on the other hand lower rod ratio's tolerate higher compression ratio's because the whole "sitting on it" thing is avoided...it is safe to say that inherantly less power will be made with a given compression ratio than on a higher rod'd engine...But with 12.1:1 CR, I was making just under 190bhp...and I wouldn't be suprised that with the right tuning, an FS should be able to handle 13.1:1 or even a little more and keep it streetable...that may not be possible on the stock rods though...

Ya, that's true. I wouldn't want to rev on the street like you did on the dyno, but the FS rods should let you run some pretty high static compression. Get some aluminum pistons(like you have), and detonation resistance would be awesome.

BTW, you can call me Josh, Install......

Uhh, yeah. I'm with twilight and Gen1GT. Our stroke is like a 92 or so while our bore is around an 83. Our engines are about as stroked as they come. I wouldn't want a stroked FSDE if it were free.

Sounds good...you can call me Jamie, Josh...ha...as well as anyone else who remembers...

 

[Installshield 2]

You figure the FS goes from the FP's 85mm stroke to 92mm...you would be at about 99mm if you stroked it another 200cc's...Which is just about a Spec V's stroke length...which has one of the higher current gasoline engine strokes ...But that engine also has more bore width, to make it 2.5L's...It would be pretty bad, but would definately make good lowend torque...I wouldn't plan on revving any higher than 5500rpm or so though...

Yeah I didn't do all the work on the pistons...I was hoping to keep a little beefier ring land to them, than what these gusy machined out (I had no where near enough experience to completely make those, I helped...but mostly watched)...so with a puny ring land, I am probably making great power...with higher cylinder pressures, and thus heat...so the detonation resistance most likely isn't quiet as good as it could have been...but its more powerful this way too...but this is the test mill, and this is what its for...

Nice links guys! Learned me something today. (thumb)

What'd you dyno?

There is the whole thread on it...it was on a brake dyno...and with some possible room for debate, which is all mentioned...

But 188bhp at 7450rpm was the best run...mods are listed in thread...

a specv's redline is also considerably lower than many inline 4 engines.

It's also a 2.5litre(spelled LITRE, not LITER. Comes from the word METRIC, not METERC. ie metre, not meter. I thought I'd fill you Yanks in, since you don't even use metric, I see no reason to change the spelling (silly) )

Nissans new philosophy is to make engines bigger, like the big 3.

the Yanks that know SAE sucks use it

vote 1 - america join the rest of the world with measurements!!!

 

[Gen1GT]

Know what's funny though? Jamie, what's the first thing they teach you when you get to college there? Metric....

 

[Installshield 2]

8th grade chemistry was the first class I ever had that forced us to not use any Standard measurements...the teacher hated standard...and I do too...I never use it...But one thing I don't understand is that tire and wheel diameters are in inches in almost every country...but they use metric for everything esle...

 

[twilightprotege]

yeah that's one thing that i've never understood....wheel diameters still being in imperial but everything else is metric....weird

 

[Gen1GT]

Ya, the tread width is in millimetres, but the rim diameter is inches...kinda stupid.

Did you know the metric system is based on water? 1cc is 1ml is 1gram.

 

[twilightprotege]

certainly did

i think the best thing of the metric system is that it's easy - everything is in groups of 10/100/1000 etc.

10mm = 1cm 100cm = 1m 1000m = 1km
1mg = 1g 1000g = 1kg 1000kg = 1 tonne

much simplier than 12 inches = 1 foot. 3 feet = 2 yard 2000 yards = 1mile
i have no idea about weights or volume measurements (ie gallon etc)

Cool, I didn't know that.

Way to be OT.

 

[twilightprotege]

certainly way OT yes....

i think we're all in agreeance - DONT STROKE THE FS
