any one know which track it better? i just got some new toys for the IROC and wanna see what she can do. i know infenion has a good track but i heard sac you can get more runs and they use VHT.

also dose anyone know how to burn chips? the more i read on here it seems im in bad need of a tune

 

**** im trying to get a chip made to but this punk ace dude playing i might just order the equipment myself,i think the sac track is better,what all you have done to your car

 

i got

custom ram air intake ( done being built but in the process of being polished)
TB spacer
ported uppper intake
ported slp runner
ported base manifold
TPIS AFPR@ 49psi
accel 24lb injectors
eldlebroke nitrous noids /NOS fogger nozzle 125hp jets
3 inch exhaust / cutout
alston sub frame connectors
245 khumos 711

 

oh ok coo what u think you'll run in the 13's?,is your motor stock

 

right now im toying with the idea of eaither a lt-4 hot cam or riping down the block and shot peen the rods and get some forged piston. im hopeing to break into the 12s but im expecting a low to mid 13s

 

oh ok thats coo,im have a 383 stroker put in mine round next yr maybe earlier,but for now im going to get a paint,some sub frame connectors,headers and my exhaust done,port my heads and tpi stuff and suspension done and before the end of this yr put a t56 in my iroc

 

I hear sac is better, but I haven't been to infenion in years.

 

nice , i want to do headers on my car but just looking at the passanger side makes me shy away from them. i really didnt think porting the heads on a l98 is worth the trouble thinking you can get some aftermarket ones rather cheap. right now sense it seems not to many people want to help tune i probly gonna have to throw down the 400 dollars and get the damm thing dyno tuned

 

i havent been to sac yet but i know the only reason i got a good launch at infenion is because i was first after all the pro street cars and the rubber was still smoking on the track when i launched. a lot of the tuners here like sac.

 

yea i might leave the heads alone prolly put some vortecs on it,if i knew how to burn chips and all that stuff i would help everybody out im not a @sshole like some people on here,i just got my injectors today and bout to install them later

 

i like sears point sac is a lil far for me but u pay 100 buck and u can race all day as many runs as u want but sears point has a way better track my cars hooks up better

 

ok better question do any of you guys go to the track. i whouldnt mind going with some other thirdgens

 

let me know time and date were u from? im from the bay area

 

100 bux huh

 

I've been going to Infinion's Wed evening drags for a year now; have even nailed two 4th place finishes. It's a great track, BUT........ you need to have your butt in line by 3pm or you can end up taking an hour to go through tech. There can be 200-300 in the street class alone. Last week I got there early, and only managed to get in two runs before they started to pull official runs; plus there was a building headwind and it was impossible to get an accurate dial in time with a couple changes I had made.

Other times, the staff is on the ball and I'll get 5 pre runs before it's time to pull out the white shoe polish.

Usually there arn't any 3rd gen's out there, but lots of Mustangers.

One other issue with the track, is that early in the season there are huge temperature changes between 4pm (97 degrees), and by 7ish, it can be in the 50's and your tyres go up in smoke.

$25 to race, $20 to watch. /and if yer a NASCAR fan, there's nothing like parking in the pit of your favorite driver and then driving on parts of the road coarse.... Nitro

 

i live in vacaville it between sac and fairfield.

 

Sac Raceway? I've been about 6 times to race this year.Sept 28 is test n tune night, Im going and looks like a couple others are going too

 

Hey Chevy Boi, Regarding your L98 heads; Are you able to do the basic head porting yourself????? Allegedly the heads clean up fairly well, but if one is to go to all the trouble to pull them off and can afford it, all these new aluminum heads are a dream! You probably already know that machine shops are starting to charge almost as much to port iron heads as the cost of purchasing a set of low price aluminums and the Vortec's you mentioned are allegedly the best bang for the buck around for budget builds.

I got REALLY LUCKY and have a machinist friend who was willing to do his magic on a set of World Products performance units that I found complete for only about $450 bucks (he's a race car drivetrain machinist specialist and currently doing up a ZZ4 platform for me). Don't mean to give any unasked for comments, nor am I any type of engine expert, but since we're all trying to knock off the same mustangs at Sac & Sear's Point; thought I should offer the info up just in case.... Nitro

Oh, are you adding the 3 inch exhaust, or just adding cutouts to an already existing exhaust set-up? I just had a talk with a friend of mine who's an executive at Flowmaster; When I shared with him that I had a full 3" exhuast on my IROC he strongly suggested I dump it ASAP for a smaller pipe. It seems that for those of us who are trying to build up the low RPM torque/horsepower on the TPI systems, three inch piping robs torque. I guess the larger pipes work better for carberator and high RPM engine's.

 

all the mods have already been installed. i got the cutout mostly for ***** and grins because it only cost me 20 bucks. the reason i went with the 3 inch is because the TPI is already great for low end torque which was making my launch diffcult. i thought it was a good trade off .

no i dont know how to port the heads but my local speed shop guy told me its not even worth trying to clean up. to his prices it will cost me about 400 bux to make thenm flow well.

 

$400 seems to be a pretty good price for now. I've heard of head work on iron heads as high as $1500! I can see what you're talking about with to much torque at the starting line. What rear end gears are you running? I just put in 3.27's but my new 700R4 spins the tyres going into 2nd with the completely shot original L98 and am hoping I don't end up in a great big pile of smoke when the new engine finally goes in. Maybe I should keep my 3 inch till I see what the baselines end up at.
Good talking with you; Nitro

 

the orginal owner said it was a 3.23, but when i was stock i was finishing the 1/4 mile benging of third or i could push the redline and finish in 2nd. that made me think i got 2.77.

 

chevy boi, I'm going to assume that's in a 9-bolt rear????? I just changed my 2.77 to the 3.27 set-up. I noticed that my around town fuel mileage went way-way up after that. I probably won't have it 1/4 mile ready till next season. I'm hoping it'll be as consistant as the G-35 I'm running now which stays: plus or minus 3-tenths of a second.

For those of you who run Sacto track; do you get many rental cars running your bracket races??? We had a guy last season who kept showing up in Enterprise cars. Oddly, one of the corporate guru's was invited to talk to someone at Infinion Corporate and saw one of his rental cars staging and threw a major fit! Nobody knows what the legal situation is, but the track officials were gossiping that he's been banned on Enterprise's computer system for life! Nitro

 

yea its a 9 bolt rear end. what is your rpm on the freeway. mines in the 2k range at 65 ish. if i had a 3.23 whouldnt it be closer to 2500?

 

sacramento deffinately.

 

think you have a 3.27. my Iroc had 3.23 and it would cruise about 2k-ish rpm at 70mph. my formula has 2.73's at 80mph im spinning at about 2k-rpm

 

sac i go like every other wed and i run pretty much all day and i here from others that sac is better....
