sup guys, i know there is a b18b turbo thread already but there are like over a thousand posts and i cant really find my answer since everyone has stock setups for the most part. i need to have an idea of how much power im making and maybe other ls turbo guys can help.

3"exhuast
1.8l b18b
fully built block 8.7.1
stock head with 3 angle valve job
skunk2 intake manifold
big intercooler 2.5 inch piping
cast log manifold

t3 t4 60mm intake and 63 exhaust turbo
gsr tranny 7k rev limit
pump gas

at fontana speedway i got a 2.303 60 foot, 8.4 1/8, and 12.76 1/4 at 109.5mph using all season street tires 195/50/15

how much whp give or take do i got?

hmmmmmm 325-350? but i would imagine you would run faster than 12.7 if you had that much

 

No way to know until you get on the dyno. These "guess my hp" threads aren't aloud, and they are terribly stupid.

 

He ran a 12.7 cause of his 60 ft. (Tires def didnt help). But did you not get it dyno tuned?

 

i doubt that he tuned the car which he should do before ever even thinking about taking it to a drag strip

 

275ish

 

im sure he is pass that i was hitting 13.8 in a eg coupe ls turbo with 231 whp

 

I like how the OP gave minimal info on the setup just that it was a built B18B1 with a low compression ratio, with a 60 trim and SK2 mani. No mention on fuel set up, how much boost, or more important to the OP's question what car the motor is in. A CRX with this combo will be much faster than a 4 door Teg.
Oh that 60ft time sucks, need to work on that and get better tires.

 

I would say under 300whp with that trap speed.

 

The other thing I dont understand is why do a 3 angle valve but dont pnp.

 

a 3 angle valve job is a normal valve job.

 

We would need to know the weight of the car with you in it on that particular day but just a rough estimate with a trap speed of 109mph and we will say 2900lbs the car is making about 290hp if it weighs less then its making less hp for every 100lbs its about 10 less hp

 

Yep a 3 angle valve job is a standard valve job. Only one of the angle gets resurfaced on the valve and the valve seat. A lot of times grinding the valve is not even needed just a quick valve lap to clean up the seating surfaces. If the valve got burnt or the valve or seat is pitted then grinding is needed.

 

i personally tuned my own car on the street by looking at spark plugs, uego wideband gauge, hondata s300 with my laptop, and the way my torque feels and although this is very hard on the street it is tottaly possible especially after driving my own car since i first got driver lisence. ignition is conservative and air fuel ratio dips to low 11s in boost to be safe(91 octane).
i figured if i payed a **** load of money to buy a program that i can tune with my own laptop then i might as well use it to my benefit instead of spending 200 to 350 for every tune that almost never comes out the way you like it. air fuel ratios and the car reacts differently on the rollers or dynos then in real life with varying temperatures and elevations. and cmon people, dont be afraid to tune your own car, how else do you think tunerz learned themselves?? its called lots of research, reading, trial and error, and basic math skill

 

3 inch exhaust
750rc injectors walboro fuel pump
7 psi first and second gear
17 psi in third, fourth and fifth

and its a ebay turbo with 60 intake and 63 exhaust t3 t4 turbo(dont give me **** for the turbo people, its literally lasted over 2 years and came off my old b20v turbo swap and still pulls strong and never smokes)

and bro how can you ask what car its in when theres a video of me racing and im clearly not the slo *** hatch that got a 18 sec quarter mile .

2330lbs integra (truck scale)
130LBs Me driver(bathroom scale lol)

 

 

damn he beat me to it...

I cant believe all the people even guessed without knowing how much boost

 

lol @ TheShodan.

why did you go 8.7:1, i dont get it...


get some good tires, loose some weight in the car and then come back with updates

 

Well, since you know how to tune it, it should only cost about $75 to do 3 baseline pulls on a dyno just to see what it's making.

And any shop with a dyno will let you rent dyno time by the hour, so you could even pay like $150 and rent the dyno for an hour, make probably 6 pulls and make minor adjustments as you do the pulls, and then there would be no guessing games.

And if you were to have a shop dyno tune it, it would cost more like $500+....no sense in that if you know what your doing, just rent a damn dyno for an hour and tear it up.

 

if its a 60-1 its really a bad turbo and doesnt have a good efficiency range. also the efficiency range is quite narrow.
