Finally made it to the track today, my first time to a dragstrip ever. Drove up to Milan Dragway tonight, took about 1 hour with constrcution and traffic. Made 3 runs as soon as I got there with my coolant temp between 220-230*, one of my fans decided to crap out on the way up. Air temp was around 90*. ALL times are uncorrected, actual times.
I ran 12.745 @ 104.88, 12.656 @ 106.90, and a 12.890 @ 106.58 (shifted into OD instead of 3rd and had to downshift). I let the car cool down for 45 mins after this, my temp was at 230 and that is way too high.

After letting the car cool for 45 mins, my coolant temp got to about 165* by the time I staged. I run a 12.421 @ 109.00 MPH. I let it cool another 30 mins and run a 12.395 @ 109.53 MPH!!!!!!!!!!!!!!!!!!!! Air temp during this run was probably around 82*. Both these 2 runs had 1.730 60' times.
I am HYPED, 12.395 @ 109.53 MPH on a hot day!

 

Ohh, man! Congrats. That has been a long road with a great destination. I would bet you can lose a few more tenths. Awesome.

I would guess you are the fastest with edelbrock headers. Lets see that car with the bottle. And scan the slips for everyone.

 

Imagine, 11s could be some tuning and a cold day away. Great stuff man

Or wait, maybe i should throw the flag on it in the spirit of recent posts here, lol. j/k

 

Hehe, I'll scan the slips and post later tonight!

 

:hail:

 

Good job.

 

Awesome. How much did that torque converter cost you? Ed, don't you run a vigilante?

 

Here are the slips of the 2 runs with a cool engine:

The Vig was about $700.

 

Yup. Once i got it in i instantly understood why everyone says it's the best single mod you can do. Imagine running 330' like a 12 second LS1 in a stock 305.
And thats why you see me beat people up for suggesting cheaper converters. Nothing wrong with sticking low budget and running something like the S10 converter. Brand new from GM for under $200 and 2400 stall, a good budget mod. IMHO though there is abolsutely no point in spending $4-500 on something that *claims* to work like a vig or yank though. $0.99 and brand X claims will get you 20 minutes of long distance calls and thats about it, lol. If you're already spending $500, don't risk lackluster performance, save the extra $200 and get the real deal

 

great job!!!!! any stangs get to see you??

 

awesome times. someday i'll hit 12s How much hp your pushing with your 355?

 

Ed, I like the Vig too. I did it along with most of my mods, so I don't have any idea how much performance it gave me. From what I read in the mags, I had to have it though.

88 350, yeah, there were about 5 Fox bodies there and 3 new GT's and a new Cobra. They were all running 13's, except for this one Fox body with a wheelie bar. The Cobra actually ran a lot of 14's and one 13.4 out of nowhere. One of the GT's looked like it hooked HARD, but he ran 13.4's all night.

Borla, I'm guessing 400 HP at the crank and 440 ft/lbs. It's a guess.

 

Sweet

 

Oh Poo on you.
Those are awsome slips Buckeye. I've been waiting for you to run it forever. Our setups are nearly twins, but your 219 is spanking my hot cam, hence its upcoming departure. I guess your no tuning is better than my no tuning. Deffinately agree with you guys, nothing like a Yank or Vig.
Buckeye, what tires were you running on?

 

Yeah, IMHO the only thing I'd use a HOT cam in is a MR or LT1 intaked engine, but even then, I would step up to a CC306 instead. Just my own opinion. I know a few others have run well with the HOT cam (Mike Davis), but I have seen VERY inconsistant times with it, and more often than not, they are 13 second times. But, if you had traction, you'd be in the 12's for sure. That tranny can't be helping things either.

I'm running 255/50/16 BFG Drag Radials, on the street and track. They felt like they hooked very well at the track. They hook decent on the street if you heat them up.

 

Buckeye,
Those times are incredible man, congrats! You and I have the same setup except I run a Yank converter. I took my car to the track last month and I ran a 13.15 @ 100 because my throttle cable broke and coasted the last 100 feet or so through the traps, so I know it has potential! I sure hope to run as good as you once I get my car fixed. BTW, what rpms were you shifting at?

 

Thanks, trust me, I'm VERY surprised, I was hoping for 12.6's or 12.7's and tune my way down to around 12.5 maybe 12.4. Now I'm gunning for 11.999 NA. I could remove the front sway bar, I have a fiberglass hood going on next week, and I still have to tune it, not to mention what cooler weather will do, it was HOT Friday, high of 90*. I know 4 tenths may be asking alot, but it's what I'm going to shoot for. If it doesn't happen, I still have the dual stage N2O sitting in the garage just waiting

I'm shifting at 6000 rpm or a hair over. Corvetteforum guys w/ this combo tell me to try 5800 for better times, so I will give that a shot next time at the track.

 

:rockon:

 

Congrats to you BuckeyeROC!! I hope I'll be around that 1/4 mile time using my "two year plan."

Ed, your thread on the Vigilante totally sold me on getting that converter. You should get a commision. I was glad I read about that.

 

Congrats Buckeye. That looks more like where you belong. With good tuning, I don't doubt you kissing 11s.

Are you using a WB O2 sensor?

 

Not yet, I have not done any tuning yet, I went to the track for a baseline run. I plan on making or buying a WB very soon though.

 

Superram/AFR heads/LPE 219 cam. That's one proven high 11/low 12 second combo! You wanna run fast and be streetable, that's one of the combos to run!

BTW, I'm selling an LPE 219 cam. It has about 200, miles on it from me, but unknown total ileage. the cam is in GREAT shape, no wear on the lobes or journals. $150 + shipping and it's yours. All I used the cam for was to pass emmissions .

 

BuckeyeRoc,

Congrats, your car serves as the benchmark for all owners of thirdgen cars with aspirations of high performance and good street manners...at least it should. And a 12.3 with no tuning, that's ridiculous. What kind of chip and total timing are you running?

Markolc,

I'm convinced after reading this post as well as others that I need the 219 cam. I'm ready to buy, if you still have it to sell. Let me know.

 

Congrats on your times Buckeye!

As mentioned, you have a combination that has been proven to work well by John Lingenfelter. John designed the 219/219 cam to work with cylinder heads that had a better than 70% intake to exhaust flow ratio. A dual pattern cam will work better with stock heads or where exhaust flow is below 70% of intake.

I love to see our 3rd Gens being a force to be reckoned with!

Dude, wow, thanks. I wish I could take the credit. I got this combo (AFR 190's/SR/LPE219) from Beach Bum on corvetteforum.com and some others over there. And GofasterFirebird and TPIGUY put the engine together, I have learned SOOOO much from them both in the past year. I picked a bunch of parts I thought would work well with that engine and put them in the car. As for the actual engine building, that was all them. They also helped me when I was ready to put a sledge hammer through the windshield while putting on a few things. And it has taken me about a full year to finish, with MANY setbacks and frustrating days, that was what Gofaster was refering to in his post. But EVERYTHING, I mean EVERYTHING was done RIGHT, by myself, GoFaster, and TPIGUY, THAT I can proudly say and I think it reflects in the times. They deserve the credit for building one hell of an engine. And lending help when needed.

For a PROM, I'm using a ARAP.bin with the only changes being a 750 rpm idle and changing the switches (such as no egr).

As for selling the engine to my bro-in-law, or anyone else, the price went WAY up last Friday, sorry.

BTW-The engine does run like it's stock with a slightly higher idle, until you put the hammer down.

And thanks to you guys at tgo for all the advice and compliments. I'm shootin for 11.999 NA now. 4 tenths is alot, but I have a few things I can still do to squeeze more out of it.

 

:rockon:

Not only did your car run faster than the M*****gs, it looked and I bet sounded alot better while doing it.

 

Yeah, and believe it or not, I think it looked better than the ZO6 that ran consistant 12.51's.

 

BuckeyeROC, where are you in Ohio? I'm just east of Cleveland. If you're anywhere near me, I'd love to chat with you about your car's mods.

 

I know it did. Third Gen's, IROC-Z's especially, just have it.

 

BuckeyeROC, you're giving me hope man!
I need to get my car running and in tune!

Congrats on the awesome runs!!

 

Were the 58cc heads custom? And if you do not mind me asjing how much were they and were did you get them? That is an awsome motor! My mouth has been watering the whole time I have been reading this post. Did you rebuild your old short block or get a new one? I think I am going to follow your combo and try using the edlebrock runner intake combo. Once again that Motor is AWSOME!

 

Great times! I've got to get back to the track myself.....haven't been in so long.

 

So you haven't even changed the injector constant in the ARAP? I'm assuming your not still running the stock injectors. I bet it's running a little rich. Another fast 165 MAF car! Hmmm, I'm re-thinking that 730 conversion.

 

GofasterFirebird, changed the injector constant. He set the fuel pressure and did a flow calculation to determine the new injector flow rate and thus set the constant accordingly.

 

AFR will mill them for you if you wish. I had mine milled to 58cc also.

 

Woah, david, Buck is on your heels! With your favorite headers!

 

When I get off my *** and head back to the track, I'm hoping for 11.8's around 115mph. Changed valvesprings, no more float and more fuel tuning is in the works. I started to say something about them damn headers in my last post, but I didn't. Just think if he had some long tubes!!

 

BuckeyeROC, Congrats on your 12.395 @ 109.53 MPH. I am running the same cam with 1.6 Crane Roller rockers and I'm suffering from a lot of valve train noise. Have you had the same problem at all? What brand and ratio rockers are you using?

Thank you,

 

S10Wildside, I'm in Toledo.

DAVECS1, the heads were "custom", AFR milled them to 58cc when I ordered them through Car Pro. They were somewhere around $1500. The shortblock is the stock block .030 over w/ the stock crank and rods and TRW forged pistons. I REALLY wanted an all forged 383, but just did not have the extra $1500-$2000 at the time, since I did so many of these mods at once. Imagine this engine with about 40 more HP and 60 more ft/lbs.?

Steve10, I have flowmatched 24# injectors from TPI Tech that I bought when the stock ones crapped out a few years ago. As TPI Guy mentioned, Gofaster did change the injector constant to 23.9, sorry, forgot that he did that.

Colt, I haven't had any valvetrain problems. I'm running unidentified rockers right now that I had a guy put in A LONG time ago when I needed engine work done. He was like, "Hey, you want some roller rockers in here?" I said will they add HP? He said Yes, a little and I said "do it". It was when I first bought the car and knew nothing about cars. I think they are 1.5 ratio Crane or Comp stamped steel rollers. They were non-self aligning, though Which is what I need now w/ the AFR's, but they should have been self-aligning on the stock heads. I might end up with Harland Sharp 1.6's sometime in the future though, I don't know, but these are doing the job for now.

David, your car should be smokin' fast. I can't wait to see some times. What do you think my car would run w/ some Hooker Super Comp's? I've been considering them.

 

Hey BuckeyeRoc,

On your 12.3 run where was your base timing set at or do you know how much total timing you were getting? The AFR's like a lot more advance than most heads, from what I've read.

To BuckeyeRoc or anyone else with AFR's,

I'm kind of confused about my roller rockers and the use of them with guideplates. The rockers are GMPP self aligning roller rockers for use with 3/8' studs. They're the same as the crane golds. I was told today by a AFR dealer that I could run these rockers on AFR's that have guideplates. He said that the guideplates would serve as extra reinforcement for the pushrod. On the other hand I've got the impression that if I run these rockers, I will need to remove the guideplates and replace them with durable washers. So what I want to know is can I run these rockers with the guidplates that come with all AFR heads and not have any problems?

 

Thanks for the info BuckeyeROC. These type of posts seem to be far and few between on this board. This is good content. I took down notes and trust me the things said here will be heavily considered this winter while I am putting together my engine. And rest assured I will post my problems and successes so more may follow in our footsteps. Nothing beats the style and grace of a fast thirdgen

 

My car picked up a solid 4 tenths over the SLP 1-5/8" Tri-Y headers with the long tubes and a 3.5" Mufflex. I would attibute most of the gain from the headers. There's definitely more left in her!

 

holy sh*t this looks like the same damm combo im going with in my iroc very soon. Im putting in afr heads(milled to 58 cc) comp pro magnum 1.6 roller rockers, lpe 219 cam, full superram intake ported by total engine airflow, and a 58mm tb, and 24# injectors. Wow if i can drop a full second in the 1/4 with these mods ill be more than happy. This info makes me crazy that i dont have the stuff installed already. BuckeyeROC, who did your prom burning, and does that cam make the car really loud, or does it still sound close to stock. Im still amazed at what u ran and theres still room for improvement but that 60' time is damn good too. later

 

Gofaster, TPI Guy, and I are burning our own PROM's together.

The car is not really that loud. My wife says it is loud, but when I was at the track, the guys who came over to talk with me were astonished at how quite it was. It has the 3 chamber Flowmaster muffler, so it's not very loud, but it rumbles nicely. It has a little lope at 750 rpm idle, not alot. Those 60' times might change. I'm considering sending the Vigilante back for a 3000 stall. Although I will carefully consider how this will affect both my ET and MPH, and how it will affect the car on N2O. This car is mainly a street car (although I am now hooked on the dragstrip) and I think a higher stall will make my street traction a lot worse, that will be a factor as well. I ordered a 2200 stall, but I think it's closer to 2400. It's hard to gauge the stall accurately b/c on the street it just spins the tires and revs to 6000 rpm at WOT, and at the track, I was watching the lights.

camarojoe, intial is at 8* with ARAP timing tables on the PROM. I did not touch anything while at the track, I just wanted some baseline times. I just let the car cool down between runs.

 

After a quick glance at a bit of data that BuckeyeROC had logged, the ks seemed to pick up quite a few knock counts (40 +) over a pretty short time interval. I think either the timing curve is a bit aggressive, or 8 degrees mech advance is too much. Also, his car is running rich from everything I could see.

 

TPI, I would have to argue against this. I know at part throttle non-PE the car has rich blms. This would make the car "lean" under WOT where it locks the blms at 128. Yet without a WB O2 I cannot determine if this proves true. The most I can really say is the tuning is decent, as indicated by the trap speed, but I am POSITIVE it is not ideal.

As far as the timing, I agree. I know the ECM is pulling timing. The ARAP bin has highly aggressive spark tables and this may be the cause. It may be as simple as turning down the base timing as you suggest.

Im wondering what suspension work was done; if any.

Congrats on the impressive times.

 

Spohn subframe connectors, Spohn LCA relocation brackets, Spohn adjustable LCA's with spherical/poly combo, Spohn adjustable panhard rod with poly bushings, Jegster torque arm, Energy Suspension poly sway bar bushings and endlinks. Stock IROC springs and shocks. All adjustable parts are at the stock settings as from Spohn.

 

Damn. Spohn got some money out of you, huh?
