Guest Mustang3.8 Posted June 21, 2009 Posted June 21, 2009 Once i get my 'vette fixed we could have a burnout contest let the memmbers decide whos te victor! I don't wanna risk being in the same situation that you're in, Jeff. My car is older then yours. I've gotten her up to 110! The last time I was speeding, I did'nt even know it until I had a county mountie on my tail.

The last time I was speeding, I did'nt even know it until I had a county mountie on my tail. only by a year!!! I've had mine up to 90 and didnt even realize it, it just feels comfortable to drive fast and take corners fast in a c4
Guest Mustang3.8 Posted June 23, 2009 Posted June 23, 2009 Very nice 'Vette, Jeff. Not as intimadating as my sleeper 'Stang. MUHAHA.
Corvette.Jeff Posted June 23, 2009 Author Posted June 23, 2009 I'm gonna need to see some spec's on the engine before i get intimidated here's the stock specs for my 'vette. Hp.-220 RWHP Torque- 290 lbs. per foot Base weight- 3,200 lbs. Those are supposedly what my 'vettes supposed to have, i need to put it on the dyno though so i can see what shes making, especially after i get some taller gears for the rear I may be getting some 2:82's for right now, but may upgrade to some 3:54's later on
Guest Mustang3.8 Posted June 23, 2009 Posted June 23, 2009 I'm not sure what my engine's spec are. Alls I know is that it's not stock anymore. Here's what I do know: Body platform: lightweight Fox Posi trac rear wheel drive Engine: 3.8L V6 with mild upgrades Flowmaster muffler MagnaFlow dual exaust tip Custom scratch built exuast system No cat converter Base Weight: Approx 2000lbs
Rudy Posted June 23, 2009 Posted June 23, 2009 (edited) Looks like you sheared some teeth off of the pinion gear. How, I dont know, but ya did it! Adding the taller gears will make it leave quicker out of the hole, but it will not affect the HP in any way, so it wont make a difference on the dyno, but it WILL make a decent difference in the seat of the pants dyno LOL...... 2.82 is a highway gear. It will be a turd out of the hole, but will only spin like 2,000 rpms on the highway and get great gas mileage. If you want quicker acelleration, get some 3.55's, or maybe a 3.73. Anything bigger any your highway gas mileage will suffer greatly. It is always a trade-off. It depends how and where you drive your car the most. Rudy Edited June 23, 2009 by Rudy

Dana 36 spicer lsd rear wheel drive.(basically posi trac.) Exhaust cut off at y-pipe(a little extra hp. ) Spare tire delete. aluminum driveshaft(stock was steel) falken 255's front and back. option to remove roof, so that takes off 30 lbs or so (that extra weight made up by sound system ) Soon to be carbon fiber roof panel.

Rudy Seems like some 3:55's are the best choice! you the fifth one to recomend those! I dont know how I managed to break some teeth off i figured it was just because its old
Guest Mustang3.8 Posted June 24, 2009 Posted June 24, 2009 You still don't intimidate me, Jeff. I still think your 'Vette is awasome.
Rudy Posted June 24, 2009 Posted June 24, 2009 you want a real eye opener then get your car onto a chassis dyno and get some real H.P. numbers. quoting factory numbers or what you "think" it has or is making never get's you anywhere . i'd be suprised if the 'vette has anything more than some 2-series gears in it currently. if you've got it apart and can swing some 3:54 or numerically higher i'd do it at this point. be wary though that most GM carrier's have to be changed to accept higher numerical numbered gear sets. meaning if you've got a 2-series carrier, you may end up needing to buy a new carrier to fit the new gears too. if you are lucky and already have a 3-series carrier and gearing, you could possibly have some high 3:31's or something similar then the swap to 3:54 or 5's or 3:70's or 3's should be okay. Dave I just got finished butting a new bigger blower on my Fox mustang. The new whipple 3.4L. Also some new Ford Racing 80 Lb injectors, a Pro-M mass air calibrated to the new injectors, 160 mm monoblade t/b. At 26.5 lbs of boost she made 768 Rear wheel horsepower, 737 ft/lbs off rear wheel torque. That comest around 940hp at the crank. I had a heat exchanger that was too small and dmaged, so we couldnt push it to hard on the dyno. The intake air temp went from 0-170 degrees in 9 seconds. And with the incoming air that hot, you wont make any more power, just less, the computer will pull timing, etc. I know with some good C-16 race gas in her she has 1000+hp at the crank, and over 800 rwhp. I will be needing a new parachute at the track this year, she should go 9.0's to high 8's in the 1/4........ Oh yeah, this is a STREET CAR!! I have literally seen a chassis dyno make people cry...... "oh it makes 500+hp"......... dyno spits out 256 LOL....... You lose around 20 percent of the horespower made at the engine, on its way to the wheels thru the drivetrain. Transmission, etc. But in the end, I always have to tell people, we race CARS not Dynos! 1,000hp is the new 500. Everybody has to make 1,000 hp. I see cars with 1,000 hp all the time, but if you cant put it to the ground with the correct suspension, tires, etc, it is all useless. Rudy NEVER GIVE UP...........................
Corvette.Jeff Posted June 25, 2009 Author Posted June 25, 2009 That is a BIG motor!! Just the valve covers look intimidating! I'd love to go in the low 9's one day, but thats a very long way away I eventually want to do a ls7 swap with a six speed, then switch to a straight axle, but that will come as soon as I get my rb powered 510
Corvette.Jeff Posted June 25, 2009 Author Posted June 25, 2009 You still don't intimidate me, Jeff. I still think your 'Vette is awasome. I wouldnt be intimidated by me either Just because i have a 'vette doesnt mean I know how ot drive it Your mustangs pretty cool, i didnt even know they made a mustang in 83' at first I thought it was a capri now you just need to find a big block to stuff in there
Corvette.Jeff Posted June 25, 2009 Author Posted June 25, 2009 Yea dave, we have california to thank for that. They made Chevrolet put a 305 in the 'vette in 74' then in 82' they said corvette's didnt pass emisions for that year, so no corvette for 1983, if california hadn't messed with chevrolet for so long in 2009 it wouldv'e been 66 years of straight corvett's and they already said they are making a corvette' for 2010, so that would have made 67 that is utill the government takes over and shuts down GM performance
Rudy Posted June 25, 2009 Posted June 25, 2009 (edited) Jeff, you know the Mustang has never missed a production year since being introduced in 1964 the Corvette however has. the interesting part as well to Rudy's big engine is that it's actually not as big as it appears! he's producing all that sick horsepower with less than 300c.i. Dave Dave is totally correct. The Physical "size" of the engine, is actually bigger than a SOHC 427 big block. But all that size is in the heads. Each head has 2 cams, and 4 valves per cylinder, totalling 4 cams, 32 valves. The actual displacement, is only 281 cubic inches. IMO it is one of the top 5 (maybe top 6 or 7) engines to ever come out of ford. The key to being able to make all that power, is from the factory forged steel crank, and factory forged Manley H-beam rods, and that the heads breathe over 320 cfm of air, bone stock. Ya gotta have the bottom end to handle it. Seeing as she is built well from the factory, you can just stuff it full of boost, without having to beef anything up, to a point. I have never removed a valve cover, and the only mods to the engine are the bigger blower, long tube headers, and a tune. She will live at 1,000 hp, but that is pretty much the limit of the bone stock stuff. But I would have to say that is pretty good for stock stuff! THe LS7, ls1, and LSX swaps are super popular right now also. Chevy hit a home run with that one. I know about 5 guys right now running the same car as mine at the track, with LS motors in them. They are all in the 9's on motor, 8's on spray. ###### "crossdressers".......... But I like anyhting that runs well, and it works, so why not!!! Although I am a ford blue bleeding purist and would rather not see a chevy motor in a ford, but they do that to us all the time with hot rods! I wouldnt do it, but it seems to work well even on a fairly low budget. I just love cars in general............ What is the story with the car on jackstands next to the vette? I cant remember what it was now, I looked at it a couple days ago. Was it a Z? I forget, I will have to go look now..... I will say, that being young not too long ago, (only 28 now) you should only try to work on one project at a time, and you MUST have something else to drive while you work on your project car. Come up with a plan, and STICK WITH IT. Changine you plan and eventual goal for the car will only end up costing more money in the end, and possibly not getting one car done, let alone 2. DOesnt mean you cant hold onto a car and keep it around until you are financially ready tho! Rudy Edited June 25, 2009 by Rudy

Prob around 2700. Light nonetheless! Hp for the 3.8L in 1983 is 105-120 hp, but you say yours is modified. JEFF- I have the same worries you do about this. I hope they dont shut down the performance division. This is why I am glad Ford has been able to avoid govenrment help thus far. I fear they want to kill every cool V8-rear drive car and truck and turn us into europe, with a bunch of little 1200lb 3 cylinder smart-car like econoboxes. I hope not.

DOesnt mean you cant hold onto a car and keep it around until you are financially ready tho! Rudy That is amazing! Now i know why people like the old mustangs I had a chance to buy one not to long ago, i think it was a 88' but it came with two motors, one was a racing motor(the guy that had it was loaded and loved drag racing) and the other was teh stock v8, i cant recall the ci. numbers because the guy had a shop about 60' by 70' filled to the brim with restored classic muscle of every kind! needles to say i was a little preocupied checking out so many pro street cars in one place Im pretty much the same way about cars, I'll lover anything that can go fast lol. wether it be a traditional rod or a Import(as long as its not all riced out) My favorite car growing up(besides corvettes and first gen camaro's) was a mid 80's supra, i dont know what it was aobut those cars, they were just so cool. Yea the car on jackstands next to the 'vette was a z, I got that after i sold my "fairlady z" it was a 83' turbo, pretty rare actually, it had just about every factory option available, t-tops,five speed manual,power windows,turbo option,drivers side light cleaner,the talking lady(that tells you when somethings open lol) the only thing it didnt have was power locks and a factory car alarm. i was stripping it to make a pro street z but lost interest after i got the 'vette. The corvette was suposed to be my first car, buyt now that ibroke my pinion gear i may end up selling it and getting a 72' datsun 510 like i originally wanted, but i really dont know right now. I mostly want to do the ls7 swap mainly because it hasn't been done yet(not to a c4 at least) and i think it would be pretty cool to break loose at any speed
Guest Mustang3.8 Posted June 26, 2009 Posted June 26, 2009 I wouldnt be intimidated by me either Just because i have a 'vette doesnt mean I know how ot drive it Your mustangs pretty cool, i didnt even know they made a mustang in 83' at first I thought it was a capri now you just need to find a big block to stuff in there Thanks, Jeff. I would'nt have bought her if she was a Capri. I've put alot of work into her. She's even got an AOOGAA horn. I'm still lookin' for a good solid 302 donor car.
