Well,

I finally got my car boosting again this morning... and my gtech pro installed for 0-60 times.... i did a before and after boost 0-60 mph times... well, im definitly not a proffesional driver

N/A - i ran 7.03 seconds
Boosted - 6.2 seconds

i however did notice that i was spooling but not getting boost until around 5500-6000 rpms... i thought that was a little high to be finally getting boost. In the other gears its full boost before VTEC at 5300 ...

now i know its a pretty warm day out, so im figuring my intercooler effiency isnt doing a good job, along with my small pipes...

so i thought the boosted time just sucked, and i figured its because im practically N/A through most of first gear, and considering i get to 65ish in 2nd gear with full boost, i'd like to figure out why 1st gear is lagging so much more than 2nd.

quick specs -

GSR Turbo Greddy 6 psi in 93 civic hatch...

If your boostin starting from 0 RPM than of course its gonna take longer for your motor to get enough exsaust gasses flowin to spool your turbo. And its gonna take a different amount of RPM to spool if your already engaged in a gear to reach max PSI levels too. 4500rpm to about 5300rpm is very common for a Greddy kit to get spoolin. I wouldn't worry to much about it.

There isn't as much load on the motor in 1st as the other gears.

ok that makes sense.....yeah im still a noob to turbo's .. but i'm learning quickly

thanks

wowsers

BB that sucka and you will boost more in 1st

soulrider4ever

do the 0-60 times seem ok?? i wasnt power shifting or anything... i get a fairly consistent 6.2-6.3 over and over.. still havent run 1/4... roads around here are too bumpy and hilly.. even our straight ones... thats ny for ya...

Not that the Gtech is the most accurate meter in the world, but it sounds to me something might be wrong....?

I was getting 6.4 to 60 before I turboed. Low 5's after. Your 1st gear doesn't sound right either. You should be able to roast em up in 1st EASY.

soulrider4ever

You know what, I have a CEL, bringing up O2 sensor and knock sensor ... knock sensor isnt wired to ecu .. go figure.. thats another topic all together.. but im guessing its retarding my timings ....

ok at least someone thinks i should be doing better times...

Afterlife1

aye as been said your tires should e roasting in 1st gear

all my LS does is break em loose anytime i hit boost in 1st or 2nd gear.

If anyone cares, I ran a 5.7 this morning launched at 5k rpm's

To GTECH Pro for teaching me how to launch!

WreckedTeggie

Are you running a p28? Because i know that when i was running a p72 with no knock sensor vtec wouldnt enage bc of that limp mode junk.. just a thought.. If your vtec is engaging then dont worry about wat i said lol

Egg-weezy

GSR turbo and you can lauch at 5000rpm?? Don't tell me you got drags on there or something....if i launch at anything over 1500rpm than i go up in smoke. Unless your burning and slipping alot of clutch to get that desired launch.

sounds to me like something is wrong, the 18g turbo in the greddy kit, gets boost pretty quick. I have a friend with a 00Si that was able to build around 8psi of boost at 6k rpms with his 3-step and it gets to 6psi almost instantly with a 1.6l turbo.

Maybe get a EBC so you can ensure the wastegate doesn't open up until it reaches its boost level.

I have no clue about my 0-60, but I ran a 8.08@87.73 on friday with my b18c @ 6psi in my 92 hatch. Although my turbo is bigger (t3/t40e .63ar, 60trim) i'm getting boost by 4k rpms in all gears.

you can throw your gtech against a wall, and it will likely give you a low 5 second 0-60....just goes to show how accurate those things are

8 sec. run on 6psi....does anybody else see this as suprizing????

1/8 mile track, 24.5x8.5x15in slicks. My greddy profec B spec II has yet to be hooked up, as I was testing the car to see what it would do off the wastegate to ensure I didn't get kicked out for not having a cage.




I was #845, #834 is a supra who recently dynoed at 525whp & 455wlbs at 18psi on pump gas with a PT74 on it. I bluffed him pretty bad at the line, which caused him to mess up some.

I also was building boost off the line with the hondata 3-step.

Oh, ok 1/8 mile run. haha, thought it was a 1/4 mile run at 8 sec.

I think it is fairly accurate, Ive had it in a few other vehicles that are stock, and they end up running what they are "supposed" to run from car and driver reports. i think if its not accurate its because people dont install it right, or dont do it right.

Maybe it was more around 4000/4500, but i let the clutch catch lil bit at a time, not just dropping it... yeah i did that before and all i get it spin and smoke, foot control.. its a brand new clutch too, exedy organic so slowly release clutch as giving more and more gas, i got barely any spin, and it was beautiful!

Egg-weezy

So you are slipping the clutch to get that kind of launch. I don't think that your clutch is gonna last to long. I had an ACT clutch and did that too. The launch was perfect but the clutch life sucked ***.

The G-tech is pretty damn accurate. Its trap times are a little different because of the way it measures them.

The Greddy Td05-18G turbo takes time to spool up, on my GSR 4k rpms to see 7psi. Not instantly like someone else said.

If your getting a CEL light your most likely running in LIMP mode which would be causing your shitty powerband.
