Just curious , are boost levels related to hp? like are your highest hp levels occuring with your highest boost levels??

 

No... There's a lot more to it then that. Obviously more boost means more HP, but only if it's tuned correctly.

 

Boost is restriction in the system.

 

correct me if im wrong but u could make the same power at 10 lbs in a bigger turbo and a less restrictive setup as you could in the stock setup at 20 lbs. boost is just the pressure and how hard the turbo is trying to force the air into the engine but with the stock setup it takes more pressure to force the same amount of air into your engine than a bigger turbo/ less restrictive setup. its all about how much air you can get into the engine not what pressure you sit at

 

Related..sure. But not a direct one. On my dyno, I reached Max boost quickly @3000RPM in 4th gear...that's where my Max torque peaked too. The boost held steady all the way to 6000RPM. Max HP was @ 5600RPM. Had the boost DROPPED at all, HP would not have reached the same level @5600RPM.

 

Boost doesn't always mean more hp, theres more involed then just turning up the boost and hoping for 900hp

Getting the right Tuner, Timing, BOOST!, etc. all matters

 

what these guys mean to say is yes, u up ur boost u will get more power, but if u dont do the other stuff like timing and such right to compliment the boost u wont get as much power as u could.

typically in little 4 bangss 1 psi = 10 hp. and if u look at what people are dynoing at 22 psi tunes and stuff, that seems to be more or less accurate. Turbo with more airflow would net u more hp per psi with supporting mods to timing and such.

 

essentially yes, More boost + more power. i know these guys are refering to timing and a tune. but thats all relevant to upping the boost. if i read you question correctly your askign if you change your boost, will it effect power, simple answere, YES!

also horsepower is only a calculation of torque

(Torque x Engine speed) / 5,252 = Horsepower

if you look at dyno charts, Torque and Horsepower curves always cross at 5252 RPMs

 

boost DOESNOT = HP. I have lower boost than I have for the past 2 years and make more power. Efficiency = power....

u changed somthing that gave u better airflow, add more boost now and it will = more hp, unless ur supercharger is out of efficency, then it dont work, but if its not then boost does = hp

if that wasnt the case, lets all take our turbos off cause we can make same hp either way cause boost doesnt = hp. lol come on man.

 

^ exactly. if all other variablies are the same. boost = Power

 

Ok dick. Take things a little too literal huh? Explain how an HPT tuned car, similar mods, similar timing etc. on 21psi made more power (a decent bit more) than it did on a custom tuned trifecta infiniboost tune making 27psi. Same components. Fueling may be a little dif but the afr's were within a few points of eachother. One make 297/324, reflash and run again, made 328hp/366tq. Less boost. Similar fuel/timing. Come on man.

Higher boost also makes more heat. Heat robs power. Upping boost is not always guaranteed power...

 

well in that case. take a S/C'd 4 banger and a big block chevy for a compro. and youre right, but you didnt just drop your boost and make more power

sounds to me like trifecta dropped the ball

 

Ported head. Lowered restriction = lowered psi

 

psi = pressure per square inch.. a measurement of resistance.

 

well 27 psi is makeing alot more heat cause the turbo is out of efficency by a lot so alot more heat soak, more heat= less oxygen in the air charge = less power. and every car is different. alot of 27psi trifecta tuned cares make 330hp and 400tq, so i guess all those little mods u made to timing and such helped the car make that extra power.

And yes i took it literally cause u said it literally. lol explain urself better next time.

 

I did explain myself the first time. Carry on

 

Oh boy, not another boost thread

Boost = restricton

Lower restriction .... gain efficiency .... make more power !
