how much whp do you guys think these bastards will put out with full bolt ons I/E/H/DP????

 

well i wouldn't say that...the catback i have has been proven to show over 15rwhp on the dyno. Of course our muffler is rediculously restrictive and our exhaust was purposely made to drain some power to keep gt sales up...if you look on the ford website, the same 4.0 makes 260 ft lbs in the explorer and sport trac instead of 240...same specs same everything, except for exhaust and tune. detuning anyone?

of course i have a much larger motor than any 4 cylinder so that also helps, you are generally right for a four cylinder application. and you're right cams are in no way bolt ons.

 

intake and a completely new exhaust (H/DP/EX) will NOT give anything more than 25 hp.

155+25=180 (and 155 is generous)

You guys must also remember that when companies advertise a "10 hp gain", they are not talking about peak HP. They are saying that SOMEWHERE in the powerband, there was a 10 hp increase

And once again, cams are not bolt-ons

 

multiple people have said that. if you are responding to my post, this axle back (not even cat back) has givin people over 10rwhp gains at peak so it is definately possible without forced induction, and that is independent dyno time, not company dynoing. i agree with you tho that it is VERY unlikely that 200fwhp will be made on a 2.4 with just bolt ons.

 

Damn everyone chill !!! not once did I say a cam was a bolt on if I did please show me the post so I may feel like and idiot lol

anyways I put up a poll so everyone please vote !!!!!!!!

the pull is based off of a full bolt on 2.4l

-INTAKE
-HEADER
-DOWN PIPE
-EXHAUST

 

i dono man kinda seems like seth is freakin out for some reason. Are you talking tuned or not?

 

hmm lets say untuned


although what would a nice tune add whp wise ???

 

guys...enough with the ricer math...that is not the way it works. No one single bolt on mod will EVER gain 10-15hp alone...the point of bolt ons is so they all work together to get the engine flowing better. A CAI may net you little gains with a stock exhaust...but better gains with a full engine back exhaust...full exhaust alone with stock intake will probably net you ZERO gains..maybe even lose HP and TQ because stock intakes are very restrictive...etc etc...

either way im sitting at 171whp from just an injen CAI and magnaflow cat-back...so say stock 2.4's do dyno at 155whp...thats only 16hp gained to the wheels.

where these cars really stand to gain some power is from a good tune because they run VERY lean and high compression N/A cars like to be just a bit rich to make full power

 

still 16whp is a great gain ...what do you estimate you might have with a downpipe and header ????

 

you will see more of a gain with a header due to the fact you are upgrading from a manifold to a header..

with a CAI, and full engine back exhaust (header, DP with highflow cat, catback) i would say around 25-27whp in total.

with a good tune i can see these cars getting 12-14whp alone on top of full bolt ons...

 

My friend BigWorm has a 2.4 with tune and downpipe and header and that **** pulls pretty good. I was surprised.

 

Wow thats more like it lol


just a spit shy of 200whp....

 

All you need to do now is throw some neutral balance shafts and a underdrive pulley into the equastion

 

Its hard to judge since all dyno's are different. My dyno was on a mustang dyno w/ injen cai and shop made axleback exhaust was 149whp and 144wtq, that + tune is 159 & 150. Some people have higher numbers with less mods but that doesn't mean they have more power.

Depends on the dyno. MIkes car maybe a bit under 200whp on a mustang but would prolly hit 207ish on a dynojet.

 

I doubt you'd get much of anyting from a tune. Maybe a Vector tune?

And not 200hp at the wheels with "full bolt"-ons either. And of course it depends on the type of dyno.

 

these engines are easily capable of 200 whp or more but i think limiting it to bolt ons will barely get it close to 200 but no one really knows for sure yet. lets wait to see what mikes cammed car can do.

 

ya but from the looks of mikes sig hes missing a Header and Downpipe which would probably
be good for another 7whp or so................

 

Avro my Vector tune was worth about 20 whp with an Injen CAI. My car with Injen alone was 142 stock after Vector tune it went to 165-168whp!!!

now add a header dp, looking at probably (conservative) +10 whp exhaust maybe another +5whp and cams +20whp.

So that conservatively is +35 whp with a tune onto 168 which should give ballpark of 200-205whp and torque shuld be close at high 180s-190s!!

Another thing everyone is missing is area under the curve. Although PEAK HP and torque numbers may go up by 20-30 whp or so the area under the curve may be even more especially with tuning on the cams!!

 

well on Jan the 05 we will see,brandon is exactly right though if one dyno is done in Ontario where its cold and another in Florida, its a good bet that the car in Ontario will get better numbers,plus some guy might just show up at the dyno shop in time for his appointment and his car is already"hot" there is also a good chance that the car that had a chance to cool down first might get better numbers

 

I can't throw these boltons on the car to after the dyno,cause it will throw off the gains from the cams

 

wrong...have you seen the A:F ratio these cars have?? VERY lean...straighten that out and it will boost power pretty good and flatten the torque curve even more in the low-mid RPM

id say EASILY 17-22whp from a good tune PLUS a more fun car to drive by turning off all torque managment.

the car pulls timing while shifting hard

 

i would say throw on every performance part you can before dyno so that we know what a certain setup is good for if you can afford it right now

 

so far its a tie in the poll between 20whp and 25whp try and get all your buds to vote i want to see what kind of of #'s we can come up with

 

Whats there to vote for its all an opnion. Even if two guys have the same parts on the similar cars the numbers are going to be different due to differences in the car (they are still massed produced), weather conditions, dyno, dyno operator, etc. Most on here have never even gone to a dyno all we have is a handful of guys who have and most of those didn't do before and after dyno's. They just went to see what the car puts out.

edit-Just take a look at celeica's dyno's. Those were done on the same dyno i believe, one to simulate a mustang dyno( with load) and one to simulate a dynojet (without load). Same car, same dyno, different dyno settings and the difference is 28whp and 22wtq.

 

With my GMPP intake alone I dynoed at 161whp, don't know what it was before the intake. I am "thinking" with intake, catback, high-flow cat, header, downpipe, cams, injectors, and a tune would put out to 230whp. This is a guess but it sounds about right. This is also what I will have eventually on my car.
