hedman 1 5/8" long tube headers $110 @ summit
2.5" - 3" dual exhaust with h-pipe $300 @ local exhaust shop

gave me 50hp with air pump delete($180), k&n($don't remember), cut air box($free), minor porting of the plenum behind throttle body($free). don't know if i forgot anything else, so look at the sig.

 

hey, take it easy! We were all new here at one time. If everyone that was new were treated this way, there wouldn't be a forum.

lighten up.

 

Craigo!
Long time no talk. I've been away for a bit. Do you still have my vacuum pump? Just kidding. :lol: Can you please answer a question for me, what the heck is an OUTLAW MODERATOR?

Sorry for the Off Topic guys.

 

will do my best although I am by no means an expert.

Im not even an expert on plug terminology, so dont laugh at me :lolg:

on the end of the plug, where you set the gap between the electrde and the bent wire, cut the bent wire at the "bend".

Use a file or emery stick to smooth the edges of the wire you just cut.

What this does is "open" the spark to the combustion chamber and allows a more efficient fuel burn. Claims of 5-10 hp have been made, but plug life is dramaticaly reduced.

 

Good description Phil, I did this on my 88 as part of a reqular tune up July 2002. I expect I'll have to do it again this July. Used AC Delco plugs. If you do an internet search you can find pictures of cut-back plugs if the desription doesn't help. It was peppier, but I haven't had a dyno done, won't have one either until I get my exhaust replaced. It will be over $100 and I'm hoping for 20 - 40 rwhp. I'll be happy with that.

 

Thanks guys for the help.. Ive beena Corvette fanatic for 10 years and Im learning and I want to get that 89'-96' Vette. So IM trying to learn all I can..

Thanks everyone

 

IM trying to learn about vettes dude

 

THanks for the help. Im just trying to learn about the C4.

 

RAY!!!!


Yup, the pump is in the garage!


Outlaws is the Texas group of CorvetteForum.com junkies! Kinda like Florida Misfits....

I figured Outlaw Moderator sounded cool since I'm a mod!

You gonna make the cruise-in a fourth year???? :eek:
it's up in the air for me, but I'm always planning on it.

 

That was funny, I'm sure they will Matt. Telling the women about your recent TB bypass upgrade gets them everytime. :D Even if it doesn't, some people say the TB bypass is worth 5-7 horsepower.

Sure they will! Telling the women about your recent TB bypass upgrade gets them everytime. :D

 

ok spanky. I got an 89 Auto coupe. I run 13.52 in the 1/4 mile with the stock 2.59 crap high way gears. I am the king of RIGGING shizil to work.
the L98 is loaded with tons of stuff you don't need....for instance a charcaol can and EVAP emissions....EGR valve, water pump frisbee, the coolant going throught the TB.... tons of FREE HP on the L98....just a matter of getting your hands dirty! i'll list a few mods for ya.

-Cut the factory air filter lid with a dremel around the edges and use a KN filter
-Use a Dremel and port the ever living shizil out of the factory air box int he throat area.....tons of improvements there. dont be shy....go to town. round it out.
-160degree thermostat and a fan switch. 165-188degrees is good running temp.
-REMOVE THE HEAVY weight frisbee "THING" on the water pump pulley...useless POS. GM should of saved the money.
-get a heater hose connector and some hose clamps....bypass the water going throught the Throttle body.
-get a 3 wire Bosch O2 sensor from Autozone....forget the part number. its 49.99 roughly in price and a TPS harness from the zone too and make a "heated 3 wire" O2 sensor instead of that 1 wire POS.
-relocate the IAT sensor from the underside of the plenum to the air box on the side....and use the LS1 IAT sensor....Autozone.... LT1 works too i think. and just use a PCV grommet and large drill bit on the air box.... solder some wire to extend the factory harness.....and then trim the harness edges to fit the LT1/LS1 IAT sensor. BIG improvement spanky!!!!
-NGK SPark plugs.....good god did they HELP out!!!!!! NO BOSCH plugs...platnum is BAD..... NGK coppers or V grooves are GOOD>>>> NO PLatnum. standard NGK's man!!!
-run tru dual exhuast....2.5"...no cats, H pipe....40 series flow masters.
-Stg 2 BM shift kit...do it your self Pu%%y...... lol i did mine....hell i do everything.
-MODIFY the MAF sensor. (just get a new one from TPIS) your old one might be bad. TPIS.....
-TPS enhancer
-Air pump eliminator kit.....but beware....you'll snap your alternator...i welded a bracket to fit like OEM style.... easy.
-port the Plenum to holy Hellls
-24lb/hr Accel injectors....but you'll need a custom chip. Hypertech can suck my DIsick. talk to jesse on here..... Ski_dwn_it
-Hypertech coil kit and MSD 6AL box
that should do the L98 some good...and most of that is free...or very very cheap. put me running 13.52 and thats with a missfire....msd wires cracked. just run AC delco wires. you better be able to rig and do all this yourself.... b/c no garage is gonna do this for you. just remember....throwing money at a car.....and parts won't make you go fast. i whoop up on C5's and HIgh dollar C4's with those magazine $$ drivers.....hehehehe..... and mines pretty much stock....jsut some slight mods...to the factory parts. cya

I knew you were a moderator, but thought outlaw moderator was something new.

I do intend to make the CI again this year. Who do I see about getting the CRUISE IN III under my name like you do. I have the Distance Traveled Award on my wall. That should be enough proof.

Take care, hope to see you in BG in May.

 

This site is always very helpful http://vette.ohioracing.com/. :seeya i do agree that the picking up chick post was odd. :eek:

 

Take it easy fellas...

I see that stingray has finally responded to one of his threads. Please accept my apologies for calling you a troll. It is true however that there is a lot of knowledge tied up in the archives of this Forum. The current Search utility is much quicker than the old one and is a great tool imho...

heres what i did to my 89 coupe and the results i got:

- 100% bone stock: 13.9 at 99mph with 2.0 60ft
- flowmaster cat back : 13.8 at 99mph w 2.1 60ft
- cut lid w K&N: 13.6 at 100mph w 1.9 60ft
- free mods (frisbee delete, ported plenum, 160* stat, descreened MAF), airfoil, AFPR: 13.4 at 1-2mph w 1.9 60ft
- MAD front ypipe, DRs, bumped timing: 13.2 at 104mph w 1.8 60ft

since then ive done a throttle body coolant bypass, installed TPIS cold air, and am in the process of installing a 2500 stall converter. i should be seeing some 12.8s at 106 with these mods this Feb when the track reopens
