I want to see what kind of setups people are getting away with on stock pistons and rods, that probably shouldnt be.

250 shots? 10 psi? Post up what you've got done and your RWHP, aftermarket rod bolts?

If you ran a crazy setup until it blew up, say what it was/rwhp and how long before it something failed.

PREDATOR-Z

200 shot dry (~50 passes/year), # 7 rod bolts failed after over 1.5 year, 40K miles.

Put another stock shortblock from a wreck and worse part, I still do it but less often on 200 because i'm Head , cammed too now, so I only need 150 at the track.

LSWannabe

So your probably around ~600 rwhp on the N20. Still running the stealth II cam?

I know there has to be more people who are on borrowed time.

I'm sure there are, in fact there have been threads about it.

YOu aren't likely to get their attention with "Are you crazy" as the title though, anybody you get in this will be purely by coincidence and luck.

I want 450whp N/A on a heads/cam setup from TSP, and 600whp on one of their TNT Nitrous Kits - as big of a shot as needed.

Drive the **** out of it till it breaks! When it does, upgrade. Then repeat.

blkZ28spt

If you can afford the upgrade when it breaks, why not go ahead and upgrade for less? You blow the motor you may very well be replacing things that you really wouldn't have had to, had you built it to hold the power and spend less money in the long run.

I don't see why people do that, but, well, they do.

Is it so you have an "excuse" to buy forged goodies?

PREDATOR-Z

No, no excuses but purely monetary. The stock block will handle up to 550>600 rwhp on juice.
And 450 rwhp NA all day long.
I learned my lesson and put a set of Katech rod bolts on, so far so good.

See over here 01> recent LS1 blocks are fairly easy to get from wreck with low mileage on them.
I got mine for like $2000 longblock (15K miles) out of a LUMINA SS (GTO/HOLDEN CLONE).
Bummer is, I got 2 sets of 241 castings just sitting here, soon to be 3 if I decide to get AFR's for the Vette.

I titled the thread as such in an attempt to try to get people to notice it.

225 shot here. I really should replace the rod bolts but, I'm to lazy. The car is in race trim right now so I'm thinking of bumping it up to a 250 shot to get it out of the 10s next week.

LSWannabe

200 shot, 225 shot I imagine that'll hit pretty hard.

Have people pushed 10 psi intercooled? Or is 7/8 pretty much max for stock bottom end?

people get away with 10 pounds dual intercooled, but most of em don't last long.

Ive had 3 blower cars running 10 to 13 lbs, and never had any problems with any of them and two of them ran past 100000 miles. I did run meth on all of them. On one I bent the pushrods, overreving it, but I thrashed them all every day very hard, every chance I got. Detonation is what breaks stuff. I realize forged is better but i bought them all new and could not see pulling the engine ect new, so i just did the basics. I always tune for less octane than i actually run for safety. The last car I got some detonation and went with 100 sonoco with the meth and its fine at I believe around 650 rwhp. My sig is on a mustang dyno and i noticed a fair power increase when I got the detonation and went with the sonoco, this was after the dyno/tuning.

Not my car, but there is a guy running 13.5 PSI from a turbo that lives near me.
Makes over 700 ft/pounds and over 650 RWHP. Completely stock valvetrain, heads and cam included. So far he has 10,000 miles on the motor with that set-up. Still running strong, but he has got to be pushing it.

CAT3

Completely stock valvetrain? I'd say he needs to be working at any one of the sponsor shops or call he has some very freaky valve springs! Kind of like calling BS, but some ppl can do what no one else has. Thats awesome if he still has stock vavlesprings.


Mine, as Cam only with bolt ons, was running 175 lots, and have run 220shot a couple times. Still running strong and will be back on the bottle soon enough.

Mr. Luos

I know, crazy.

The car is tuned perfect. Probably why it has lasted so long. Stock heads, stock cam, so I would assume the rest of the valvetrain is also stock.

blkZ28spt

You listed your assumption as fact.

Chances are that he at least upgraded the valvesprings.

Mr. Luos

iTrader: (9)

Sue me.

Why upgrade valvesprings though? Stock rev limiter, stock cam. Does the boost put extra pressure on them?? Not familar with boost, so I just don't know.

650RWHP 680RWTQ on a TNT 200 shot been through about 10 15-lb bottles.

blkZ28spt

Yes, it does. FI guys often replace springs in order to control the valve, even with a stock cam.

FYI: When it comes to making claims about what a car is running you should never list assumptions as fact. You only end up making yourself look ignorant and/or losing any credibiltiy you may have had.
