Stock Pistions on Spray

drunkinamustang · Sep 14, 2004

From what I hear they come with steel forged pistions that can handle a nice shot, but what about the rings and stock heads w/ oversize valves and 1.7 rr, 7angle vavle job.

i'm sure that stockheads can handle it but i'm pretty sure that we don't come with stock forged pistons. biggest shot guys run on here is 100 i think, being safe. btw: killercanary is in the low 12s with the stock b- na though

correct... we do NOT have forged pistons... we have some hyper crap pistons in our cars.

T_5.0_N'works · Sep 14, 2004

A guy I know sprays a 150 shot and has for over 2 years and it was fine on the hypercrap pistons. I might spray a 150 shot prety soon to get my numbers, then settle back down to a 100-125. I defenitly wouldn't go over 150 on hypers, but that's just me.

You guys have hyper pistons in your cars and you can spray them just fine.

Joes95GT · Sep 14, 2004

First of all, the pistons aren't hyper. They're hypereutectic.

Secondly, you can run (a larger shot of) nitrous if you get the car tuned for it. I wouldn't put a 200 shot on the motor without a wideband.

Not if, but when my car goes at least 12.0x, I'm going to hit it with a 200 shot and see if it'll go 10's. This is all assuming I don't blow it up in the process.

I run a 125 shot on mine..... 2 years of juice (starting with 75 shot and working my way up) no problems so far.

Hey Joe, worry about getting to the 60' first at least before crossing the 1320 @ 12.0's

wytstang · Sep 14, 2004

You can spray a stock 5.0 with a 150 shot and be good (with supporting mods of course) I personally won't venture higher than that.

Ain't that the truth too.

After further examination, I lunched a few spider gears in the posi, bent the left axle 0.013" out of round, launched the driveshaft, knocked bolts loose on the driveshaft loop, busted the rear seal in the trans up, and boogered my emergency brake cable up.

Luckily I hadn't got the recall on the E-brake, so that's going to be on the list. Along with bulletproofing the 8.8. The new Detroit True-trac looks like a real sweet piece, so I'm going to look into one of them.

Once the car's back together (and if it stays in one piece), I wonder if I can hike the front end up on a completely stock suspension?

You're an excellent example of what someone is capable of doing, and I respect you for that.

Most guys take everything at once and grenade it. You started slow, learned, and tuned as you went along; something most don't have the patience/know-how for. Hence the reason why I always say keep it under 100.

before i bought it, my car had been molested with a NOS dry kit 5115. the valve floated in #4 and shattered the piston spraying in 5th on the highway....

all the other pistons were fine when i pulled the motor and the compression was good, to bad the former owner did a shade tree rering on #4 and it would knock on the wristpin. thast why i had to replace the shortblock with my D&D with a few forged goodies

Sounds like you did a number on it. Beefing it up is a good idea if your gonna be racing it with a tire out back. Stock T5 still??

ps- I just ordered my accufab 75mm TB I felt the car was too fast and I wanted to slow it down a bit I also ordered a 30lb pro m 80mm maf to replace the 24lb one im using now. The 65mm accufab and 24lb pro m should be for sale by next week

Someone will take them things up in a heartbeat. You won't have a problem selling them. The 75 will kill velocity though, especially with the TFS heads.

Yep, still the stock T5. I swear it's Pro-shifted or something. I learned to drive on this car. I've learned to power shift on this car. I've missed so many shifts in this thing, it's not even funny. I've got probably 250+ powershifts on it. It's adopted the name "Nails". I'm just waiting to see how much more it can take before I bust the input shaft.

Joe was kidding. We both know the 75mm TB is perfect for my car and his I can't wait to get it on! I was looking at my 65mm and how the c&l pipe bolts to it and its hard to explain, but its clearely a restriction and it matches my TFS opening perfect

I'm gonna spray a 125 dry shot when i install my 5115 "cheater" kit

94TURBO5 O · Sep 14, 2004

I used a 100 shot on a stock internal motor and never had a problem. I didn't blow the stock HG's until I ran 12#'s of boost with the S-Trim.

Thanks Joe, I was at a dyno shop the other day... they had just installed a Zex Wet kit in a 02 SS for their accountant. Guy has NO knowledge of nitrous and they ran the 75 shot first (got 66 to wheels out of it!) and as soon as they did that, they said - lets try the 100 shot. Which meant the 125 would have been next.

I jumped in and said.... how about he drives it like this for a month or two to get used the power. I used wrecking his car as an excuse, but I was really worried about the motor too. Some people see something easy and take too much advantage of it. I ran the 100 shot on my stock engine and could hear and feel the car was at it's limit everytime I sprayed it. That's when the injectors and other upgrades in my sig came into play. Good thing too. I was lean as a mofo on top end. The 125 shot would have been the end of my motor.... no doubt about it.

125hp compucar wet kit here for a year and a half...tore apart in the search of more power. Never broke a thing...cept a few hearts
