I just want a real world Idea of how fast this guys mustang maybe. its about a 91? (mass air flow 5.0) 5speed gt with 3.73 gears, underdrive pullies, offroad h-pipe but, stock mufflers.

I raced him before because he claimed he beat ls1 camaros so I had to put him in his place and shut his stupid *** up
but, now I guess he has a problem with getting his *** handed to him and I mean handed! he kept asking me to race him and from word of mouth he bought a nitrous kit and plans to race me with it on. I don't know what shot he has I can only guess he will use the biggest one in the kit 150-200? what should he run? I just want to know because if he wants to play like that I can too just would rather not but, he keeps asking me to put money on it like 500.00 he seems pretty cocky and needs an *** kicking

with those mods I would say high 12's maybe mid 12's it all depends on what shot he is using . I would say take the 500.00 bet and put your own nitrous on it and stomp him,but you have a 400 and I definetly wouldnt recomend spraying on a 400.I think he should take you unless you are running more than a bone stock 400.Your sig only says 400 tpi so I am assuming so I still bet your running a low 13 or high 12 depending on your gears so its your call wether or not to put money on it.good luck

if he's running a 200 shot on that stang good chances are it's gonna sling a rod out the side of it. if he's smart he's running less than a 100 shot even then he's only putting around 330 hp out.

good luck and kick his ***!

A 5.0 can safely handle a 150-175 shot from what I have seen, and have also seen a 225 shot on a stock 160,000 mile motor.

As his car sits, he should be in the low 14s or so NA and with the nitrous, I would say low 13s to high 12s also!

Good luck.

What was the difference between speed density and mass air flow? I know the L98s had speed density for a year or two, was it 1990? Thanks. That Mustang should have a good chance on you if you have a midly modded 400. With a low revving 400 and TPI, he will kill you top end. I am going to say that this comes down to the length of the race. No doubt it will be close, but it's all you for at most an 1/8th of a mile. Once your TPI hits its threshold and he sprays, you'll just see the stang's taillights. Unless i've completely missed something... Just let us know your mods.

There's been a few guys around here that I know of to get away with spraying 250 shots through stock motors. The transmissions are always the first thing to go under that much power though. Most people around here tend to run 125 shots and I'll guess that if he can get traction, it might be a mid 12 second ride.

Yea and I wouldn't spray on a 350 either ?? If you have a 4-bolt main 400 screw it shoot that sucker up with some insane go-go juice. I would say a newly rebuilt 400 could handle atleast 150 without any problems.

I'm not sure why everyone gives the 400's a bad rap. They are just a SBC on steriods. Go have some fun with the dual torque master set-up you have (400 SBC and TPI).

Later, Garrett

brodyscamaro

you seem pretty confident....
what are all your mods - or better yet a ET and MPH...

it would also be helpful to find out how big a shot he is spraying

anymethod

no one knows about the speed density and MAF difference? I'll just ask on the engine board.

he is spraying 150 I found out today, he is such a ****! he still keeps talking ****. I will use my 150 shot too then. yes it is a 400 with the 4 bolt mains and I have forged pistions in it. IF IT WAS ANY OTHER PERSON I WOULD NOT CARE TO EVEN RACE. I figure I wooped him with out nitrous so it should be about the same thing. I run a low 13 well 13.35 N/A lots of tire spin. when we made the bet he said he did not have nitrous and he only wished he did. so I guess he kinda messed it up when he came in and had nitrous today.

let em run around usin that spray everywhere for a couple weeks then race em to like 130mph so his engine blows apart. let that moron ruin it for himself and help make the streets a little safer.

Nic

In a nutshell: speed density uses a pre-programed table in the computer based on MAP sensor readings and intake air temp readings to control fuel delivery whereas mass air operates off a hot wire. The air coming in through the sample tube in the MAF cools the wire down, and the voltage it takes to maintain the temperature tells the computer the volume of air coming into the motor and then it adjusts the fuel delivery accordingly. On a stock computer, MAF is better because it adapts to larger cams, better flowing heads, etc. better; however, once you go to aftermarket tuning, the SD system is more desirable.

brodyscamaro

Those motors can take a 150 shot.

anymethod

Thanks Nic, I somehow understand that. Reason I asked was cause a buddy of mine has a 90 IROC with a speed density L98. Thanks again.

If you got it buddy, use it. No mercy.

yeah when used properly, this dude sounds like an idiot. probably is on the nitrous button from the stagin lanes to the return lane at teh track.

brodyscamaro

Although he doesn't sound smart, I't can't make that judgement yet. Just because he talks **** means nothing...
There are a lot of people out there that talk a lot of **** that know what's up in the sport/hobby...

well, I raced him today. he was surprised I brought the car and was asking the other guys what I did. they played dumb and said I put turbo blue gas in the car and I said I would take him with that , towards the end of the day I asked him when and where we were going to race and if the 500.00 was still the amount he got kinda quiet but, still keeping his cool said he did not care. he looked like he did not want to race at all as he could not come up with a road. I said I would race for free because I didn't want to take his money.

We went down a road that was dual lanes and at 50mph we nailed it I kicked sideways alittle (not much) and took off with a good sec. of squeeling tires, we raced from a couple slower rolls with about the same result (I took off like hell everytime) then we went out to a back road and ran from a stop he did use his nitrous off the line but, we stayed door to door through 1st then second gear I had my nose ahead of him, I figured hell with this and armed the nirtous and just took off like crazy. I ended up with about 4 cars between use when I hit the mid of 4th and stopped.
he asked me what I did and I only replied I did the same thing as you. he laughed and said he could not figure why I was leaving him like that. I didn't act like a jerk just kept it cool and then I went home after talking
It is gona suck for him at work because he talked all that **** and I took him. everyone else will just talk trash to him now but, I guess he has it comming with the way he acted.

A 150 shot on a car like that should be in the 12's easy on street tires and trap around 110 or so. I have stock gears and just 6-7psi of boost and ran time in sig. My cousin dropped .6 in the 1/4 and gained 8mph from a 75 shot spinning bad. All depends on the kit and whether it is set up right. A local tool in town rna a 150 shot (dry) and was slower than my cousins car with a 75 dry shot. You need at least 800psi bottle pressure, max of say 1000 works good. BTW.. NOS brand dry kits are flywheel HP gain, most of the wet kits made by other companies are close to the RWHP gain in there rating.

Spend the bux on a blower. It will be worth it in the long run as long as your compression isnt too high. That way, when he runs out of juice, you always got it on tap.

I like my sC..got it used..my total im mods are like $1600 or so...
