Are those times corrected for elevation or not? Where did you race and how was the weather conditions? With that MPH and some traction a torque converter and some slicks you could be in the 12's I think. Its true was my engine builder said today, "Why do you want all that power when you can't plant it? You better off spending your money on traction mods and setting your suspension right." This is what he said when I told him I was going to add a D-1SC Procharger like yours to an engine he's building. 383 AFR heads, Miniram, DFI, Long tube headers, all the goodies probably 450+ NA h.p. I'm now considering spending my Supercharger money on mini-tubbing my 87 Trans-am GTA.

What heads, cam, chip calibration, rear gear, transmission are you running Maniac?

 

dude your car is flyn....cut a good 60' and your in the 12s easy

when i went 13.0@110 i had a 1.97' 60 which is still crappy...but i had 2.77 gears

get a drag radial and mild stall and the thing will fly

 

Awesome Maniac,Like said before cut a sub 2 sec 60ft your there.I cut a 1.79 on my 12.60 run.Hows your fuel pressure under boost and how much are you seeing.How much boost?Just get some dam drag tires Whats the elevation at the track?I think NED near me is 400ft above sea level.Im going to cal you thursday.

With a stock TPI (stock cam, stock heads, stock intake, stock chip) with SLP 1 3/4 headers, stock tranny with B&M shift kit, 3.23 rear gear, ATI Procharger 11 lbs. boost, BFG Drag Radials, I ran 12.76 @ 112, with 1.9 60 ft. time. Temps were around 70, humidity at 70%. This was at Kansas City International Raceway, which is about 800ft. elevation. I ran all sorts of E.T.'s but always ran around 112 MPH in the quarter. I'm sure that with some slicks and gears my car would have ran low 12's with that high of a MPH. Dyno'ed at 350 rwhp, 413 rwtq. Hope this gives you an idea of obtainable times and E.T.'s.

 

Hey 383TAGTA, Sounds like you are building the same combination as I have. I have: 383, AFR heads, Mini Ram, DFI, Long tubes, etc, etc.

Haven't started it yet, the motor is all in and wired up. Just finishing up the 8 pt. roll cage. I'd like to compare notes sometime.

 

actually NED is less than 100 feet above sea level (I asked them). I Believer they told me it was 40feet above sea level...

but those are sweet times

 

I thank *** I saved my money and just bought airflow heads instead of a procharger.

Maniac, are you a little dissapointed in your times or, at the very least, your mph. I have to agree with GoFaster, although he is a ****, that you would have done better with a set of AFR's and a big cam. You would have also saved yourself 2 grand to spend frivilously.

the reason why Maniacc's times are bad could be resulting from massive rich condition

also the efficiency of the D-1SC impeller at that low of boost level (10psi) isn't that good and its spinning very slow

Thats why with a p600b and the same boost level would probably hinder higher levels of power because you are spinning it much faster

with my procharger i went a full 2 seconds faster and gained 19mph

did your heads/cam do that?

 

TPIguy,

No, i'm not disappointed at all, the times that i ran are on bald street tires @ 30 psi, i drove 45 mins to the track, went thru tech inspection, and jumped right into the staging lanes, I was shifting @ 6000 rpm's and I also have to let completely off the gas for the trans to shift into drive. I feel with drag radials, and a better track(Milan sucks!!!...everyone claims to run 2-3 tenths slower there), and learning how to leave better, and fix my trans 12's will come very easy. then i can put on some AFR's and a cam and shoot for 11's...i picked up 1.1 secs and 11mph from my previous run without the blower. I have now only made 6 runs total on a 1/4mile track so i'm still a rookie with alot of learning to do.

89prochargedroc, i am not experiencing a rich condition, to my knowledge, accrding to my auto-xray, i was running at 744Mv. @ WOT

To each his own. But why stop at just heads? Let's compare your times with my 305 (without a blower).

You (350): 13.51 @ 102 mph
Me (305): 14.071 @ 98.004 mph

Keep in mind that my engine was built to be blown, so IF it was built to be naturally aspirated, my times would be better. So the difference is in reality closer than the numbers themselves. Proof of this comes from Tim Burgess' wife's 1984 Berlinetta. It has a fresh 305 TPI, automatic with stock converter and 3.42 gears. It has a completely stock TPI intake system, ported STOCK heads and a Crane 2032 cam (same as mine). He has run 13.80's. Kind of makes AFR's on your 350 seem rather.... slow....

You: 12.33 @ 114.83 mph (Nitrous)
Me: 12.05 @ 116.62 mph (only 10 psig boost)

You neglect to mention how much nitrous you are running????

Maniacc's results are on a STOCK engine and driveline. I feel 106+ mph shows a high potential for decreased ET's.

Willie,

Did I mention that I have a stock long block?
Stock runners?? stock TB? Besides my centerforce clutch and redline oil my driveline is stock. 3.23 gears? 100,000 miles? Only a crappy Hypertech stock replacement chip?
Or that I have only almost 9 to one compression? Sure your car probably has low compression but it is a blower car so it doesn't count. Your mention of an 84 camaro running 13.80 in reality means little to me. Without a mph figure how can I really judge the power of the car? Stock runners can only flow so much air at atmospheric pressure. Think they are holding me up?

Also, my times are at Milan dragway(2 or 3 tenths slow right?) All I am saying is that my N/A times and mph are a poor indication of the afr heads performance. I purchased the heads for use on a larger motor so that is why I have low compression. I have 305 runners. Cams really don't come that much smaller than mine. Hell, your little 305 has a bigger one in it! And finally since 99 percent of us are on a limited budget going fast for cheaper seems better to me. The only thing that I have that cost more than a part on your car is my afr heads. My car would be faster than your car if I had 500 bucks to throw at it and I still would have far far less money in it. But being a 20 year old college student it will have to wait a bit. Sure your car has power all the time and you are going the different route with a 305 and all but when it comes to 1/4 mile performance my car was built for cheaper with similar performance. I am not saying that I went the fastest for cheapest because I am sure there are those people that have far exceeded my cost per mph ratio. Judging from what I have seen from your car and larry's car going fast for cheap wasn't in the game plan.

 

also, how can you be TPI guy without a TPI? Does your "TPI" stand for something besides "tuned port induction/injection"?

 

Gofasterbird,Willie times are very good considering the factors involved.And Willie forgot to mention to you the track he runs at is over 3000 ft above sea level,so yours and his times are much farther apart if you consider this.When I first bought my P600B back in 1996,when you were about 15 I might add,I went 12.6 at 111mph at NED,on a bone stock Iroc,A/C full emmisons,weighting in at 3860lbs with me in it.For $3000,the amount I spent on the blower kit,AFRs and a big cam would not even touch what I ran considering the high weight of the car.And considering the car had never even had the valve covers off in its 65,000 miles.Do the math,my weight VS. 1/4 mile mph,easily 400hp you wont touch that with just heads and a big cam,not even close.Really I dont know why you would even waste your time pulling off the stock heads just to put AFRs and not even consider the other parts of the intake system.But you do fail to mention what I will now here,your car was originally a TBI 305,right?Consider the $$ for the conversion to 350 and TPI and the $$ per HP is about the same ,maybe you spending more to get where you are.Im sure All of us Supercharger owners are happy as this is my second one,if you would like to praise the benifits of N/A cars their is a forum for it,its called "You will always be second best forum" Have a nice day!

Dude, I pulled a motor out of a wrecked 1990 iroc and I paid 1100 bucks for it. I then sold my 305 tbi for 550 to some dude that put it in his truck. Expensive huh? Also, I do not have a big cam as I have stated and stated again. Maybe you should read slower.
As for pulling my stock heads, my car is a work in progress and when I get money I will bolt on an intake. Also, since my car is not naturally aspirated then how can I be on the "second best" board? And it seems that Willie's times are corrected just judging by his sig. Also, I am not sure the point of telling me that you purchased your procharger when I was 15 other than the obvious math involved in that statement.
Also, I doubt your car weighs 3860 unless you are in it. And if that is a weight with a driver, it really isn't that heavy for a thirdgen.

 

TPI GUY, I'm new to this site. I was looking over your signature and found it ironic how close our setups are. I was running 14.1's in my chevelle until I added a 248 252 .510 .515 cam. Now my car turns out 12.70@109 on street tires. I shift@6000rpm. Before you do anything else I would get a bigger cam. For some reason dart heads respond well to bigger duration cams. I hope this helps!

 

Gofasterfirebird,

As you can tell, Willie and Darren have become very good friends of mine, thanks to 3rd gen.org. Hell they probably know more about my car than i do!!!(j/k)

Anyways, my car has 60,000 miles on it, there is no reason at the moment to replace the cylinder heads, valve seals maybe. So i thought i might as well get the s/c now and as time and money allow i will replace the things that break with Hi-po parts, like my trans, which i will replace this winter along with the converter(Pro-built 700r4 and a Precision Industries approx. 3000 stall converter.) this car is not my daily driver so if it does break, it just gets parked until i get around to fixin' it.

My game plan is not to be a 1/4 mile racer, just have a BADA$$ car that, looks good, and is somewhat dependable and whips most peoples butts on the streets (and not for money), and is a RUSH to drive.

Basically its just a big toy.

I'm very happy that your car is faster than mine, it doesn't really matter to me, as long as we all have fun, and share some good quailty info and a lending hand if possible, when needed.

Have a good weekend all, see ya's all monday.

later

Hey Sting Ray, do you have your heads ported. If you know anybody that has ported the Dart Iron Eagles, I'm looking for info and pictures as I plan on porting them myself. They flow pretty well up to .400'', like 208 cfm, and .500'' they flow 209. Anyways I have to say that Maniacc did pretty respectable considering a stock cam and heads, and that if he says 1/4 mile times don't matter, that's really just sour grapes. Also you have to admire GoFaster's times with a 206/212 cam. There aren't a lot of college kids out there (myself included) that are willing to pay for school and trade beer money for a few mph's.

 

Gofasterbird,I dont understand what you came here to say.Maybe you dont have the whole picture.You say Maniac should have spent this money on a big cam and AFR heads,your times are 13.5 at 102.Maniac has told you he has some issues to work out with his car that are totally dependant on what his car turns in the 1/4 mile like a slipping trans,turning those times on street tires,plus first time at the track for starters.He has told me and reiterated it here that he doesn want a 1/4 mile car his car is fast for the money he has spent,I have been there before,my car had a tranny that wasen't slipping,drag radials and this wasen't my first time at the track,still don't believe me click on my link in my sig and go to my pic page,there is a pic right there capturing one of the numerous 12.6 runs and you can clearly see the mph,this was an improvement over a 14.6 at 93mph stock.If you want to judge this way,you would not even touch such a combonation for the money.The car mine and Maniacs,idle like stock,run like stock,ac and creature comforts work well no emmisions problems but the power is there when you put your foot in it.You still havent told us how much of a nitrous shot you are running?In the long run the nitrous you are using will become more expensive(bottle refills)then what the blower kits cost.So your argument of a n/a combonation outpowering a supercharger kit,and doing it for less is skewed.Take all the facts and the truth emerges.What anyone doesnt want here is someone having there combo nit picked "because you thing he should have spent money on big cam and heads"and he is "slow for what he spent"Cmon a congrats is in order for this thread to begin with.Congrats Larry! I think we can all find something to agrre on.

Isnt that a tad bit lean?

I'd shoot for AT LEAST 800mv.

Just my opinion though.

 

Yup, Maniacc. Sounds like your fuel pressure is dropping off somewhere and you are running lean. I had the same problem as you. I never really noticed it on the street because i'd really never get into third gear on the street at full boost, well because i'd be doing about 110mph

BUT

When my in tank pump was dying and i was losing fuel pressure, my times were almost exactly like yours. Check to make sure you aren't leaking any fuel around the FMU and by where the fuel lines connect to the rails and make sure your fuel pressure is going up with boost, you should be at about 80-100psi in third gear. If not you HAVE A PROBLEM

 

89ProchargedROC,

I had adjusted the FMU some, playing around on the street, but like you said, it's hard to get the car in 3rd at full boost in the city, i just need to adjust the FMU alittle bit more, i was seeing around 60-70 psi @ the track, and no leaks to be found, i do have the stock intank and the ATI supplied pump.

TPI GUY,and that if he says 1/4 mile times don't matter, that's really just sour grapes.
HAHAHA...that's funny. But I really DON'T care what times my car runs, if i did, i be at the track every wednesday and friday, spending all my money to go faster. I rather just go to car shows and cruise the streets of motown, as a matter of fact the car is getting put away for the winter very soon, and out comes the sled (snowmobile for sunnystate people)

Ah, but see, you do care because you took the time to make a post. Then you engaged in discussions about how you can get your times lower. Then Willie and 89prochargedRoc proceeded to beat GoFaster Firebird about the head and facial regions for suggesting that Maniacc could have taken $5000 and gone much faster. I have to agree. For $5000, I would have returned my 1LE driveshaft (I know who you are) bought AFR's, a miniram, a zz-409, a stall, a trannny rebuild, and had cash left over. Don't get me wrong, I'd like to get a D-1 also, but I think that you put a power adder on AFTER you have reached the naturally aspirated power production capacity. If not, you really aren't doing justice to the power adder itself. When GoFaster pulls up to Maniacc on the street and puts 8 car lengths on him at the end of a .25, he makes the rest of you with D-1's look bad. Don't get me wrong, I'm all about the D-1, but you have to help it work for you.

 

I have been asked and e-mailed countless times asking me for 1/4 mile times, not to mention quite a razzing at work. So i went too the track and BAM. I have Times for all to see.

this is the reason for this post.

Yes i am quilty of asking how to make my et's lower, but i'm just getting ideas on what i should do next (besides fixing the trans)

As for the D1, i love it and would recommend it to anyone, this is not a only AFTER you have reached the naturally aspirated power production capacity mod. this blower would not be good on a 13:1 motor. Now that i have the blower i will build a motor someday that can handle 18 psi of boost. but not until my 350 goes poof!!!

When GoFaster pulls up to Maniacc on the street and puts 8 car lengths on him at the end of a .25 I'll pull up next to him, smile and tell him hes got a badass car!!!

And please dont think that i paid $5000 for my blower

well it's been fun,

Unless you got some promotional deal b/c you were one of the first with a d1, that blower was quite pricey. I know b/c I seriously considered buying one identical except for the polished intake. I applaud you for actually going to the track unlike so many and teaching many people that running fast is more challenging than just bolting on a blower.

 

i dont understand your problem gofaster

i bought a blower and 24lbers for about $3200

all i had was headers......with 2.77 gears

i went 2 seconds faster and gained 19mph

DID YOUR HEADS/CAM DO THAT?

thats all i'm asking.

 

Do you actually read the posts? I just complimented Larry.

 

Just ignore the crap slinging Maniac and keep wrenching. After the tranny is fixed and the other bugs are worked out, and the A/F ratio is tuned and timing dialed in + you get some traction you will be balistic as well as styling.

nice times Maniac...with some better traction and tunning 12's are in your future...to everyone saying "Oh you should've bought this...should've done that"..its HIS $$$. He's running a bone stock engine...bone stock tranny..again with traction he'll be low 13's. I think an order of congrats is in store...Maniac just ignore some of the ignorant *******s.
