These setups are so simple but yet so efficient.

Slightly off topic but what clutch do you guys run with these 350-400 hp setups? I'm interested in a smooth and not so harsh engagement one that can handle that much hp/torque.

garagelu

Wow this is such an old thread and overdiscussed. The clutch I have and love is dxdracingclutches.com. The engagement is like stock and will hold 450-500 horse.

number80

Ooops I did a search and didn't see the date. However an over discuss thead is a good thread IMO.

((sr)) kelly

im getting my car tuned next thursday... ill post the numbers


sr20det
2871r .86
hks step 2 264 cams
hks dual rated springs
nismo 740cc
greddy fmic
apexi pfc
hks evc6
255 lph
z32 maf
apexi SS filter
3.3 inch catback
3 inch outlet and dp
Greddy intake mani
Vibrant tubular exhaust mani
no a/c
ARP studs
apexi metal HG
Z32 fuel filter



hoping to hit 400 whp with 20 psi, and bumping the rev limiter to 8k

350 may not require 100 octane or higher fuel...but for those of us who live in arizona and nevada where it reaches 125+deg in direct sunlight in the summertime...that 100 octane is REAL important in a proper tune out here

every cali tuned car ive seen come to vegas always has either A) cooling issues or B) fuel delivery problems that only occur when they arrive here

i can understand back east where the level of octane at the pump can reach 94...but for us west coast people that live in extreme heat with HORRIBLE ambient air temps outside and lack of oxygen...and we can only get 91 at the pump...100 octane is one major reason our motors dont go explodey when reaching higher HP numbers and using em in the summer

Yea i did 353whp on 93 octane pretty easily. Also clutch i use is a Exedy Stage II. Its a little harsh on engagement but very drivable. ACT Extreme Street/Strip would probably be pretty nice.

Good point! I certainly never considered this at all.

I'm certainly not comparing the east coast to your area (I've been in the dead of Summer in Death Valley, White Sands/Bliss, Hood, and Iraq, so I've got a good idea of dry heat), but you're also looking at an area where I live that does see mid to high 90s/100 in the summer, but also at obnoxious humidity levels. However, even with us having 93 (94 is getting harder and harder to find), the majority of us with decent power either:
-Don't boost around during the heat of day, and wait till night
or
-Have water injection.

As much as I hate to say it, I don't understand why more and more people don't have water injection...SOOOO much cheaper than race gas...

can't believe this thread is still going on lol. I guess I'll update on my car. I got the sc61, BC 272 cams, 810cc injectors, new tune, ect put on. Had problems with it for about a month (thought it was the tune). turns out that megan FPR's are inaccurate as hell. It was running lean at 60psi of FP. put my stock fp back on and ran perfect afr's. Still had some slight problems with the way it was running. driving home from a friends, car dies and wont start back up. Turns out one of the comp cam valve springs broke on me, bent a valve and dinged a piston. So now I'm looking to fully build my block and 600hp

Also turns out that BC cams require cam gears due to being degreed wrong or whatever causing low compression numbers. I only had 90psi of compression across the 4. My friend had the same problem, bought cam gears, degreed the cams and got all his compression back. So a heads up guys using BC cams!!!!

jobestudios

Looking for some insight as to what to expect with my setup.

Stock S14 SR20DET (stock manifolds, stock head, stock block) (zenki)
GT2871r .64
Apexi Power FC w/ Commander
740cc Injectors
300zx maf
Apexi Power suction air filter with 3" intake piping
2.5" charge piping on a Vmount intercooler with 18x11x3 core size
Apexi AVCR set at 18 psi
3" turbo-back straight pipe
255 walbro


Think I can clear 350whp? I haven't seen too many people with 2871r on a s14 sr post up?

I know venom injectors aren't the greatest, but should I even consider running them temporarily until I can source some better ones?

Are you seriouse? Is it only the 272's? This would explain a whole lot. How did you come to this conclusion??
How did this affect your A/F's before the gears?

Just swapped in a 2871R....no real engine mods, except for 740ccs, greddy divided turbo outlet, greddy rspl front mount, etc.

Made 305 ft-lbs and 318 hp at 17 psi.....tuned pretty conservatively by Jeff Evans in PA.....He said cams should add another 40-50 hp no problem. Power band feels great.

Like codyace has said, flooring in 1st and 2nd is almost useless...even from a dig in 2nd, flooring it results in traction problems, sometime in 3rd too!

I am running PFC D-Jetro....god it is so nice to not have a MAF....the response is so much better and the car runs way smoother

keep in mind his is on a DYNO DYNAMICS Dyno...

BC Stage 3 cams

dont mind the spike, the boost controller wigged out on this run....

A lot of power, but seems lag-a-riffic to me.

Evans uses dynopack dyno..., where the hubs mount directly to these splined axles that spin inside this hydrauliclly load-changing device.

^ How does dyno dynamics numbers translate into other types?

Dyna-Packs are good dynos.

They can do most of the the things the Dyno Dynamics does without overheating with overheating

so in comparison they are not as good as an overall investment imo.

for tuning and power pulls it should be fine, but they overheat pretty easy.

We did 291 HP 280 Trq at 15.5 psi on Jordans car with a stock s14 long block.

what tires do you have that you are breaking loose that easy? do you have a clutch type LSD? should help a bit.

Take your dynodynamics number multiply it by 1.16 = usually equals Dyno Jet number.

Dyna-Packs are usually like 5% less than Dyno Dynamics depends on some other factors, including that the mass of the wheels is actually

removed from the equation.

yeah my setup is a bit laggy. if i used smaller cams and stock intake plenum i could avoid that but i prefer the peaky powerband.


from what ive seen personally Dyno Dynamics read 13-15% lower than Dynojet #s.

Steve have stock VLSD which fails, I know

Also, have 245/40/17 Kumho MX all the way around, with a 220 treadwear rating.

I need to fine tune my AVC-R to make the boost come in smoother.

Either that, or lower the boost in 1st and 2nd.

On the highway, going 80, downshift into 4th, and she pulls like a bat out of hell

Yeah HP is fun huh, wait until that isnt enough.

It will be on most road courses.

but the addiction overall never goes away when messing around

Did you have any problems with the Crower Stage 3 cams? That number seems a little low.

__________________

Brian W.

no problem with the cams and ive installed them in other motors too.



you really think that # is low?


it would be almost 440whp on a Dynojet.

and im running 93 octane pump gas.

Evans does great tunes. Hes a real good guy he tuned my brothers car that made 650whp on race gas. We also took my brothers car on a dyno dynamics and we got the same numbers on that dyno. He also can weld sick intercooler piping i hope that i will get tuned by him in the future.

jspaeth

So according to Steve's calculation, to go from Dyna-pack to Dynojet numbers, you should multiply by ~1.21

hmmm...i like the sound of that!

Jeff is incredibly talented at what he does, and is as honest as one can get with advice. He's not one to deal with BS, and is usually pretty reserved, that is unless you start picking his brain.

He is certainly one of our countries Top (if not the) Honda Tuners (and tuners in general).

Haha, boost= crack and crack=kills

Don't get tooo caught up in the numbers game with these dynos. Get it to the strip and give us a trap speed Wait till you get some cams in there, you will be very very very happy (get JWT s3's heheh)


And 440 whp on that .86 Brian W? Seems a bit high to be estimating like that. Not doubting, just would love to see an actual number....with that said, are you guys the closest DynoDynamics to me (Poconos PA)....I may need to take a trip to satisfy Steve

evans has a pretty nice dynapack... My one friend got tuned with his ls-vtec 2.0L with a 3076r - made 420whp on 17psi-pump gas

hes mainly for hondas, but will tune almost anything. And his dynapack might read high - we took same exact car to a dynojet and it made 385. coulda been the weather or some other factor ???

hes always booked pretty solid or at least he was last summer.

Naw, more like 1.16

Yeah I would say more like 420 range

Whe I did 375 on the DD I did 419 on the DJ

And a great shop. Very clean and professional. His Dad's T-Bird shop is awesome too!

I've seen it read that way as well on some cars, and then damn near equal to D/J numbers on others...

he's always booked a few weeks, sometimes months in advance. again, great tuner for anyone in the PA/NJ/DE/MD/NY area....
