hey guys I would like to go to the track maybe sometime this summer my car has been running stronger than before, good 'ole lb9! After finally getting some parts tuned, I've definitely noticed a positive difference in the feel of the car.

Good news is I have a job to save some money for (yay!). Not sure what my plans are, but I would like to look into some performance parts, just starting with the basics. Right now I wasn't sure if i should look into a catback as I have an aftermarket muffler (dynomax), but not the full catback. The engine is stock so there's plenty of different things I could choose from!
some things i had in mind..
-slp intake runners (and airfoil?)
-hooker cat-back
-better coil? (hei system)
-polyurethane bushings/front end rebuild kit
what headers are smog legal for Ca? probably not time for headers though, just curious? Any other ideas for beginning to modifiy my engine?

sorry for missing dyno day

- Robby

Hey Robby, yeah I'm sorry we missed ya too.

The best deal on SMOG tube headers are probably the Edelbrocks, they bolt up practically stock and can be had pretty cheap.

Do a full 3" exhaust after the Y-Pipe and it will make a big difference.

catback is a must, 3" also high flow cat and headers are good any time. hooker, hedman, SLP, edelbrock all have CARB legal headers, I'd go with the hookers. airfoil is a waste of money, SLP runners aren't the best but will be great on the LB9(TPI was designed around a 305 so runners don't do much on them). also try a intake manifold. you have the incap coil so their are lots to chose from accel, MSD, jegs, hypertech, crane cam, pentronix, etc. also may want to get an ignition module. oh and with the coil make sure you check you coil to see what color wires you have (red/yellow or red/white)

anything to improve the engines breathing (intake & exhaust) is a good place to start

Glad to hear the car is running better Robby. As others have said, my vote goes to 3" cat back with headers, good luck. Keep us updated.

Let her breathe in and then exhale out, and you'll be on your way to high 15's.

ok, I'll go to the track wed(7/19) to see what I can get for a baseline run now that it's running a little better. Though I wish I could get the car to run a high 15 as is, I would be happy with a low 16, at least something better than the 16.4's I was getting before @ 83-84mph. I mean it's a stock 305 auto unknown on the on the cam/heads really, but assuming nothing more than stock specs. I was leaning towards the Hooker cat-back for first mod, or the runners, similar price, but not for sure which one is most effective right now with a stock motor.

thanks for the replies everyone,
-Robby

ps. Del, do you really think I need better intake/exhaust to hit high 15's?

me and travis will be up there

I'd go with the cat back and cut the airbox and slide in some K&N's(if you haven't done so already)

I think you should be in the low to mid 15's now

eric cut my airbox (thanks), and i put k/n filters in that should supply the 305 with plenty of airflow for now right? oh yeah, does the a/c delete have any affect with letting a few hp up, i did that as well.

yeah a little the whole less rotating mass thing

Depends, maybe your first runs were a fluke as it was just your first time.
I meant something simple as cutiing the airbox/inserting k&ns (which you've done) and a nice full exhaust should knock off several tenths.
If you can hit a 16 flat tonight, I'm sure you can get 15.5's or better with exhaust/headers.

Damn Robby, wish I could make it out to the track with you, I want to see who is faster, some other time I guess. Good luck. Oh, I agree with the others, go with headers and cat back first, it will make the most improvment on your stock engine. Be sure and post how the track times go.

Did y'all hit the track?
Let's see some #'s.

you could always put that bad boy on a diet

think he ment wednesday 7/20 tracks not open on tuesday

duh!!!

oops im trying to scrounge up some money so i can go tomorrow as well..

gotta get my timing and afr tuned it.. mostly timing. and watch me run the hsr and get 14's

rofl, my bad.
i thought today was wed. all day.

you tricked me too



ill go in my ferrari....gonna be about a month before i can afford the rest of my stuff but atleast my heads are in the mail


and robby i can get you a high flow cat for a steal haha...
magnaflow that is a good place to start exhaust. although i dont see what the big deal is i still ahve stock exhaust dual cats and i have decent size anyway with no crimps, so i think the only thing restrictive in my exhaust is my manifolds, and muffler..

ill do my best to try and close up the shop early hasnt been happening lately been frickin drama i was there until 6 last night fixing one of our latest master tech f**ck ups damn him, hes gone by tommorrow he stinks... so ill be there around 6 how about you robby you gona be there

I'm really going to try to make the track tommorow. So look around for me. I gotta do some errands in the morning though, so we'll see.

yes Eric I'm going, what's the ferrari, I know you really don't have an actual one working at the smog shop. At the track I hope someone can help me out, cause I can't get my hood adjusted right, so I can't open it barely, it takes forever for it to click and unlatch, crap!

ferrari enzo aka 87 pontiac grand am aka daily driven


ill bring my ratchet with 10 mm...well try to get your hood adjusted...

Why would your hood be out of alignment, did you take it off?
My hood used to require a little shimmy everytime to pop it.
I sprayed a little WD-40 on the entire latching area and adjusted the circular black *****/bumpers in the front and mine pops without fail everytime.

okay, after going to the track w/ a few of you guys I was able to break into the 15's with a 15.9x@85.xx. Best mph was 86.1x but only a 16.01 et. Good baseline for the stock motor, now we'll see how I can improve with some exhaust work. Thanks for coming out guys, had fun!

- Robby

'atta boy, that's awesome.
did you do anything different from last time or has your cars overall condition just improved?

anybody else run?

since last time things I have changed: Accel 8mm wires, Accel cap/rotor kit/timing/tps/tv cable adjustments, a/c delete, k/n filters, dynomax muffler(not catback).

Travis' car ran high 13's @99.xx, urbanhunter(tony?) ran high 13's/low 14's i think, and that's it I think.

thanks for the compliment Del, is your GTA ready for a 13.xx soon?

Amazing what having a car in good tune w/ a few adjustments can do.
1/2 a second improvement is sweet.

Well I feel pretty confident that my runningwaytoorich is the cause of my lackluster time & hope to have it corrected before months end.

I'm sure Travis will agree that having a car outta tune sucks, especially after investing in the Stealth and not seeing a better timeslip.

. ..stay tuned

ya HSR sucks.. well ya know.. spend 700 dollars on the swap and run a tenth second slower then before the swap..

thats right i couldnt muster anything better then 13.9 and i had like 9 runs in no joke. and i had to wear a helmet for the first time damn ******.. i can run 13 flat on nitrous no problem but 13.9 uh oh lets bitch traviz out and make him wear a helmet. lol

same mile per hour too..

but hey i adjusted my timing from -6 to +6 and i lost half a second but for the first time in history i hit a 100mph trap!

i'll take the hsr off your hands?

no way! i decided that losing torque down below was expected so thats why my times sucked off the line.. and because stock heads cant flow with the HSR.. i didnt gain enough top end to make it worthy so thats why my times are the same.

new heads and cam are coming quite soon!

3 months im expecting.

what kind of heads and cam?

iron eagle platinums and as of today ive changed my mind again and now i think i wanna go with the CC 0x-503-8 grind

aka 503/510 lift 224/230 duration

XR276HR

hmm im running these brodix heads (p&p)http://store.summitracing.com/defaul...h.asp&N=400033 and a zz4cam

wow all brodix heads. plz pinoint which ones lol..

*** it i hate links

dang, 9 runs? haha.
what were your 60's looking like?

2.1's

Nice job on the times Robby. I want to get out there so bad and see what my car can do, work is taking up all of my time on those nights for now though, gonna be a while before I can make it out though.

Travis, sorry to hear about the dissapointing times and improvments with the hsr, that sucks man. Sounds like you just need better heads and cam though to take advantage of your hsr. Good luck, see you this week at work. Oh, my dsl is working now so I can keep up with you guys again.

gratz!@

now whens the party?

party? where? when?

Me, vinny and 3.4 are heading back to the track next wednesday - I know I'll break high 13s now that I fixed the rev limiter problem (tranny was filled too much causing it to not shift fast enough).

ill go to watch.

no reason to run i know my car is slow.

Travis, party, not sure on that yet. Don't worry, it will happen though. Give me a few more weeks and I will start planning something.

Good luck at the track guys, don't forget to post those times.
