could b18c1 puts out 350whp with turbo? - Honda Forum / Acura Forum

aznswtlkr · 03-02-2004, 10:01 PM

this guy claims he can produce 350whp by slapping on a t3/t4 turbo on a 150K b18c1..is he bs or can it be done ? and i'm not talking about internal buildup or headwork.

RedlinePrelude · 03-02-2004, 11:10 PM

If he's not gonna touch the engine than yes he'll produce 350whp for like 5 seconds after the turbo sools up the first time it's driven........ than all you got to do is get out of the car and pick up all that's left....lol

350whp is more than double the power assuming around 150whp stock ........ I think he'd be really lucky if the thing would run for the first 500 miles......it would take around 20psi...and no stock honda can do that stock....

know what happens when metal pieces get tossed into the turbo?
if you want to find out, boost the hell out of a b18c with no engine work

umm ... there are a plethora of stock block b16's with 300whp ... and even a handful with 400whp.

that is with the b16 .. with the b18c1, it should be that much easier, since it has more discplacment.

On Honda - Tech . Com there was a stock b18b1 with a Lovefab SST manifold and Precision SC61 with 300whp at 9psi. So it's all in the tuning, and knowing what you're doing .. and it's definatly possible.

I've seen dyno charts of a b18c1 producing 357 whp on 11 psi.

PM-Performance · 03-03-2004, 05:11 AM

i know someone who has been pushing a stock c1 for a while now , he put down 379whp and like 290 something tq on 11psi

dsrspwr · 03-03-2004, 03:24 PM

look on the vid forum, theres a vid with a white b18c hatch on 22psi, i have a seperate vid of that hatch dyno'd at 750 whp

RedlinePrelude · 03-03-2004, 03:37 PM

yeah but that hatch isn't stock engine.....not doing 750whp

Were talking about stock engines here....no internal work
Somehow I just can't imagine pushing a stock motor way over twice it's wheel horsepower.........I mean you probably can but for how long? one, two days??? lol
and even if it's tuned right.....the stock internals would not take that much abuse for long........
Hey it's just my opinion

dsrspwr · 03-03-2004, 04:50 PM

stock internals, 22 psi on stock internals

j/k

i wasnt sure what he was asking

and you know what about turbo's??? hmm

earlier you said... "350whp is more than double the power assuming around 150whp stock ........ I think he'd be really lucky if the thing would run for the first 500 miles......it would take around 20psi...and no stock honda can do that stock...."

it doesnt take 20psi to make 350whp..... its been done at way lower psi... then you said even if its tuned right a 350whp on a stock block it wont last???? TUNED is the key word.. there are some hardcore tuners out there , and there alot of different sizes of turbo's, ways to lower compression on stock block to handle that much HP, for instance a thicker headgasket.... just my opinion

RedlinePrelude · 03-03-2004, 10:00 PM

Tuning is one thing but even if you have the best tuned car you still gotta thing about how much can your rods hold and bearings hold.......you can have a good tuned car but you're still putting twice horses on stock parts....and some can't hold that much.......

About how I got figured it takes 20psi to make that much power
QUOTE FROM HCI May 2003 page 62:

Suppose we add a turbo to kit to a 160hp b16a motor. Befor we can calculate the power potential, we need to understand that our 160hp B16a is already operating under boost or more accurately, atmospheric pressure.
Our normally aspired B16a operates with 14.7psi of pressure forcing the air into the cylinders when the valves open. This atmospheric pressure is a constant at sea level and a given temperature can naturally affect ultimate pressure.
All we have to do to calculate the power potential af any turbocharged application is to multiply it by a percentage of the aditional boost pressure. If we configured our turbo kit to supply 14.7psi (1bar) of boost on top of the atmospheric pressure, theoretically our 160hp B16a should produce 320hp (2x160). This same formula can also be used to calculate different boost levels. If we only run 10psi then our 160hp B16a would produse 269hp (10/14.7 + 1 x 160). To calculate the power gains at a given boost levels, simply divide the boost number by 14.7, add 1 and multiply that number by the original power output of the normally aspired motor.
If we upped the boost pressure on our 160hp b16a to 20psi, our new power output would be 378hp(theoretically). This same formula can be applied to any motor and boost level, as long as you know the original power output of the normally aspired motor and the desired boost level.

Now you know
So I took 20psi / 14.7 = 1.3605....
then 1.3605...+ 1 = 2.3607....
then 2.3607...x 150whp(on a stock b18c1) = 354.08....whp
I used whell hp..... and thats with a really eficient turbo with the the compressor map matching your engine...

getting stuff from magazine's =

PM-Performance · 03-04-2004, 05:26 AM

dude stock rods can handle alot more thna people think , i have seen stock honda rods go close to 500whp without probs. its the pistons you need to worry about , they are prone for ringland probs.
i doulbed the hp on my R and drove it for a while with no probs and i beat the piss out of it. the only reason i rebuilt is becuase i wanted more power. i didnt have to though.

uoboarder · 03-04-2004, 10:28 AM

To answer the first post...

I was doing some thinking about it and I figured that you'd need about 10-13psi of boost. With that you'll need amazing tuning and a good way to manage the system. Its possible, but I doubt it would last long. Those ring lands would take a dump on him fairly quick.

RedlinePrelude · 03-04-2004, 03:43 PM

Well that's what I ment....... If you tune it right....you'll make it but how long will it take for the parts to give up on you.......on a stock engine
And why getting stuff from magazines is bad????
I read = I learn and I think the guys at hci know more than you
What do I know about turbos? I have one....so I know a little
