Hey guys, got a few pulls on the dyno the other day.

'00 B16a2
MemoryFab whale ***** intake
new stock NGK iridium plugs and blue wires
'01 spec ITR intake and exhaust cam
DC 4-2-1 header (2.31")
Megan resonated test pipe
Greddy Ti-C catback exhaust

untuned whatsoever on stock P2T ECU



What do you guys think my next step should be? Should I be dissapointed with these numbers?

I know I should get some kind of management but I am completely lost in that area. A lot of people praise the s300 but honestly, all of the parts on this motor combined cost less than what an s300 cost. So at this point,that is just out of my budget. What others should I be looking at?

Also, I am located in the Tampa area. Which tuner should I consider? This dyno was done at proven power and i must say, they have a pretty competitive price for N/A tuning. Any advice?

Thanks everyone

 

Well I'm no expert by any means, but If I had to take a guess I would say that those numbers are kinda low.

If its a stock ecu then you would most likely benefit from lowering the vtec point a bit so its a smoother increase in hp.

do a run with vtec disabled figure out where hp starts falling off, put vtec at that point... simple enough.

the runs look pretty consistent although on a stock ecu what do you expect

I'm a neptune RTP fan, www.hrtuning.com will help you there, although to be honest for what you want you can get away with s100, but Honestly if you wanna learn a bit more then just have someone tune it, id recommend a option that allows you to do it yourself such as NeptuneRTP.


You could probably get away with adding some more ignition timing at top end and keep adding it until HP falls off.

you can also benefit from some more low end grunt "not sure if thats possible with a b16" but have a more agressive ignition ramp up between idle and where ignition timing starts to flattin out twords highrpm and load.

Comments always welcome good or bad.

The guy at the shop said the same thing,"add more timing at the top end" and "lower vtec engagement"

How do you do that? That can only be accessed with a management program right? I mean you dont actually move the distributor?

 

Where should i look for these chips? I see a whole bunch on the local forums like "chipped P28" etc etc, is it safe to buy used?

 

You need to buy a tunable ecu.

Neptune RTP is one example www.hrtuning.com
S100 is cheeper although you cant monkey with the tune later without special hardware.. No bueno for me so I wouldnt get it.


basicly a chipped p28 will allow the tuner to open up the ecu remove the rom chip replace it with a romulator make changes to the tune once its dialed in and all peachy write that program to the eeprom and replace it back into the ecu.

generally there is a huge price difference between a chiped version and something which allows you to connect a laptop to and tune yourself.

Stay away from EBAY chips, Stay away from SAFC's, Stay away from Gredy Emanage.

these are all fail.

Its probably safe to buy used if you buy on here in the correct locations.

--Edit The only time you would move the dizzy is to set base timing correctly, after that hands off... I suppose in a pinch you could advance it a couple degrees but that will advance your ignition map globally, you might see gains but this isnt an option for tuning, its a bitch fix.

 

I see....

so would it be cheaper to buy a virgin P28 or something already chipped?

 

Virgin p28 no, chipped yes.

I would recommend buying it all at once like NeptuneRTP with a already modded ecu.
I'm not affiliated with HRtuning in anyway, I just like the tuning package a bit!

If your thinking you will get crazy gains you wont, but its a good base if you plan on adding a turbo or building NA.

Personally I wouldn't build an NA b16 run low boost less then 8 pounds. and tune your ignition timing very conservative!.

 

How much power do you think I can extract from this set up? 10 hp? 15hp?

Should i make any part changes before getting it tune?Different header? Should I invest in an IM/TB?

 

well I have no idea how much power you can extract, I am not a B16 expert someone could chime in here.

having some 4-1 headers with a large collector will probably open up some top end power, you will probably see tq go up slightly too, although having 100lbft of tq on a b16 is really really lacking "I think"

I'm not really sure what gains you will see with a larger throttle body.. I'd search around or maybe someone else can chime in to see what the max hp/tq numbers are for a b16.. I only know the H22 side of things.


I don't want to start throwing around numbers as gains you will achieve because I just don't know.

I do know however it makes a huge difference having a proven good set of headers 4-1 style with large collector, good intake "high flow filter" and everything else in working order.


good luck.

 

cool, thanks alot for the feeback man!

 

Sure thing.

But see now I'm curious what kinda power people actually get with a b16A with only bolt'ons

 

Your car is probably making 140 whp SAE corrected on a dynojet.
You cannot count the little hop at the top of the dynosheet, you also shouldn't really be reading uncorrected numbers.

If you really want to have the car properly tuned get your self an obd2 to obd1 ecu jumper & a chipped obd1 ecu & have the car dyno tuned on ectune :-)

I am guessing the wideband print-out you have isn't accurate on that dyno sheet.
You will not gain gobs of power power from tuning a simple setup like yours. The gains you will see will probably be some midrange & top end power. I would want to see an accurate a/f output from the dyno.

 

^that is quite disheartening to hear. From your experience with these motors,would you say that figure is low?

Would you say that 160whp tuned is a reasonable number to reach for with these components or should I make changes?

I was thinking of ditchig the intake for a vstack and maybe go with a hytech replica header.

And yes I should be picking up a chipped p28,harness,and a tune from you guys soon. And package deals you have going on?

 

I would have to see a real a/f output that is accurate to give you an opinion.
Most stock b16 engines only make 150-160 whp on a dynojet sae corrected.
Put them on a dynapack & they will make 160-175 whp.

Concerning package deals, everything is priced competitively, there are no bundles until you get into a hondata system etc.

 

WOW stock meaning as it came from Honda,not even bolt one? Does that mean my numbers are 20hp BELOW what this stock motor makes?

 

i think he meant internally stock b16s.
the numbers he mentioned are pretty common, anywhere from 150-175 whp depending on setup and dyno used.
Torque numbers look about right. Stock the b16 is only 110lb/ft at the crank so getting 110 at the wheels is alright. With a tune you might pick up a bit more torque across the board and 5-20 whp depending on many many variables.

I would recommend getting a tune though, it will have a huge effect on how the engine "feels" and things like responsiveness and fuel mileage.
