ran the local 1/8th mile last night
 
well all in all i got it to go 9.033 @81.08mph but my turbo wasnt spooling in good in first and second, next week ill run again and i have to adjust the gain on my boost controller.. it help out by turning it 3 clicks on the greddy pro fec type s

should be in the high to mid 8's if i canlower my 60' from 2.1 to a 1.9

gxl90rx7 09-15-07 02:28 PM

that mph is good for mid 8's at least

boost_its_what_for_dinner 09-15-07 03:15 PM

thats what i thought but i have to tune it still and get the gain tured up some.

Not bad. Where did ya run, Music City Raceway? Your trap speed does show a faster ET in your future. My GSL-SE/TII swap ran an 8.89 at 79mph at huntsville and you are trapping 2mph faster.

boost_its_what_for_dinner 09-16-07 04:33 PM

85rx-7gsl-se 09-21-07 12:29 PM

i meant i wasnt lauching hard. but anywhere from 2.1-2.3 but i hit 84 mph @a 9.011. need a tune still and my tps harness has a bad spot in it or something, it will go in and out some times then if i wiggle the harness it will come back to life??
but turbo doesnt spool fast at a launch ?? thinking the ebc is hooked up backwards. likethe vacuum lines are on the wrong things i.e wastegate vs. compresssor housing nipple? btw its a greddy pro fec type s if anyone has the book of instructions to look at?

85rx-7gsl-se 09-24-07 01:34 PM

Yeah, you could definently pick up some time on your 60ft. I have found that for the most part, you trap speed remains close to the same despite your launch as long as you don't miss a gear or something. I have run times varying from 10's to my 8.89 pass with trap speed being about the same, 78-80mph, with the 60ft being the key. My 10's runs had 2.5 60ft's, vs. 1.9x 60ft with my 8.89 pass. Some Drag Radials could help alot. Thats what cut my 60ft's from a best of 2.3's to 1.9's. Good luck in the future.

boost_its_what_for_dinner 09-24-07 08:51 PM

im not having traction issues though turbo spooling issues...

85rx-7gsl-se 09-24-07 09:20 PM

Hmmm, don't know on the turbo spool issues.

boost_its_what_for_dinner 09-26-07 09:09 AM

well i ran again last night and hit 84.70 mph @ 9.1. 60' is killin me??

any suggestions to help it out

i have traction
launching at 3-4k
slipping clutch off the line
and wfo all the way down

might turn boost up to about 14 psi....

umi415 09-26-07 12:44 PM

Yeah, I might be wrong but I Think you should be running about a second faster with your setup. Practice makes perfect, just keep trying nothing will help you more than getting to know your car. I mean we can give you tips but it seems you already know what to do. Try launching between 4500 and 5000 rpm and see were that takes you. Good luck and I know you will be posting lower numbers soon.

PS. I ran 8.62 with a stock turbo, intercooler, 550/850, SAFCII, RTEK1.5.

gxl90rx7 09-26-07 01:46 PM

ive noticed my bnr stage 3 doesnt spool well in lower gears too. But in higher loads, like 3rd or 4th, it starts to really come alive. i havent had mine down to a strip yet, so i dont know if i will have your same problem though

boost_its_what_for_dinner 09-26-07 04:10 PM

i need a tune................................... gxl90 can u tune pretty well? or do you know anyone around that can?

boost_its_what_for_dinner 10-14-07 05:37 PM

well well well... i did it

this past friday night i went all out and ran

8.3 @ 90.71 mph 2.1 60' and beat every import at the track

would post pics of the after race winners circle but they havent posted it up on the web yet.

rotatech7 10-15-07 08:03 PM

@ what psi boost?????

boost_its_what_for_dinner 10-16-07 01:15 AM

well my data logger (pda rteck 2.0) battery died so the last 2 runs dont know for sure but i turned the boost controller one click (greddy pro fec type-s)from what iwas previously running at 11-12 psi so im guessing im at about 12-14 maybe 15 at some point. will know more nex ttime when battery is full


plans to hit high 7s soon

bbs vert wheels with dr's coming soon to help out

one more thing

if im running 90.71 mph in an 8th mile what times/mph do you think i could get out of the 1/4mile??

im thinking about a low 12 @110+

jkimbro 10-17-07 10:53 AM

The 90mph is a good mph, but I'm thinking not a low 12. An 8.3 is only good for a low 13, high 12 second pass.

Until you learn how to drive, I can see a low 13 at 108

drive?? my car doesnt do well off the line and it comes to life from second to 4th gear so i sure i can almost top 4th gear out in a 1/4. but ill know soon

jkimbro 10-17-07 02:37 PM

It doesn't do well off the line, because you don't know how to launch....IE learning to drive. Not being an ass, just letting you know that you need to work on your launch.

boost_its_what_for_dinner 10-17-07 08:40 PM

im launchin @4500 and im running bbs's with a 225

how much power do you have jkimbro??

ZAN_TUNING 10-18-07 12:30 AM

8.3 @ 90? you will run 12's at around 115 +/- ;)

boost_its_what_for_dinner 10-18-07 12:32 AM

thx i thought i would run closer to that too.
