My friend has a stock ls b18 motor(no vtec) with few mods obx intake (short) and a obx muffler, how much power do you think he has ?

 

Not much.

 

Im guessing about 115hp blah weak !!!

94 and up LS's have 140 hp and i believe 130 torque (not %100 sure) stock, so im sure he's got a little more power than that.

 

OBX products proabably decrease performance

Anyways Ricer way of adding it up

140+ ricer mods = 157 hp y0

In reality not much

He's talking wheel hp.

Even then thats not much whp my buddies ls has about 128 whp i/h/e, plus he didn't specify whp.

 

i did a baseline for my 93 integra bone stock so i could get an idea of what i was looking at, and it dynoed at 123 whp and 118 tq,

and a baseline for a 92 gs-r bone stock was 141 and 110 (i forgot the tq, but it was around there)

we dynoed a ls motor in a civic w/ stock exhaust, stock cat, and stock intake and it put down 98 whp.we dynoed an integra w/ an obx muffler, obx cold air and high flow cat and it put down 128 whp.

 

word its kinda hard to **** up an intake.

 

B18a 130hp at the flywheel and B18b 140hp.

 

speaking of rice, just run with open throttlebody, and open exhaust, i'm sure the buttdyno will yield good gains.

Wow, that cat must have been really clogged.

Assuming a 15% drivetrain loss the LS should dyno around 119 or so to the wheels, stock. I'd say your friends numbers with boltons are pretty decent.

i think the b18a has 130
and the b18a1 is 140
all b18b are 140

Misinformation.

90-91 b18a1 = 130hp
92-93 b18a1 = 140hp
94-up b18b1 = ~140hp.

you stated exactly what he just did.

 

Thats only a 6% loss. I doubt the TQ number was that high. (Damn thats sad 110WTQ is to high) I know you are not trying to spread bad info so Im not trying to bash your numbers. I do know that the TQ on the B17 and the B16 are close so the number was probably closer to 100TQ-104TQ

I know I sound petty but I think 110 is just too high....

141/160 = 11.8% loss
110/117 = 5.9% loss

 

no, the 90 - 91 b18a1 was rated at 130, but for some odd reason, the 92-93 b18a1 put out 140. Technically the same motor, same code and everything, but there are minor changes that brought about the hp diff. like the 90-91 has a diff intake manifold/throttle body than the 92-93

 

The Integra has a drivetrain loss of 13.5%. So this thing should make 128 at the wheels. (5HP worth of mods).

The 13.5% works for the HP conversion from CHP to WHP - the torque conversion isn't linear.

Can't you read?

 

a b18a will only barely make over 100 whp
maybe like 110

 

Everyone who keeps putting the bhp numbers at 90 to 110 is full of **** and don't know wtf their talking about the ls b18b makes about 127bhp so kid don't listen to all these haters and idiots that run their mouth and are of no help.
