hois making more than 450 stock bottom end??

[4vlover]

hey everyone

im just wondering how many of you out there have the balls to make more than 450 and still beat the brakes off their car with stock internals. as you may have seen in my other post, I think I might find myself in that club!!! haha

[jeffro]

just a ticking time bomb... prob going to spin a bearing.

where are you at power-wise? how long have you been there?

i will be installing a procharger in the next month. i'm hoping for ~430-440. i'm currently on the bottle. my installer wants me to keep the nos, back off the shot to a 40-50 and spray it dry. that just sounds like a bad idea to me!? BUT, if you guys are pulling it off, maybe it won't be so bad spraying once and a while?

I've never been on a dyno but im probably mid 400's got about 2000 miles this way.

[mach1guy20]

I'll be dynoed this month on spray I should be 480-500.

[SHAKN' 04]

Used to daily it but started driving my other car. I prob have about 5k miles with the power its naking now. About 2k before making 455 on 5psi

[SuperMach1]

My car has been making over 400hp for the past 45,000 miles. No problems here.

[jeffro]

how much over? over 450?

[fastlane]

I am at 475/445 since January. I have about 5000 miles this way and no issues to report.

[Thor]

Check the Power Adders thread for supercharged and turbo numbers on stock bottoms.

[BlvdBrzr]

I beat on my car very hard when it was making 460rwhp with 8 psi through and On3 Turbo 70mm Turbo.

[Mach828]

JayB is running 505hp in his.

There was a guy on here a long time ago who had an eaton swap and 100 or 150 shot. He ran it that way for a full season. He didn't blow the motor until he bumped it up to a 175 shot. IIRC. He's about the only guy I think who has blown one up due to power, and not due to other issues, such as going lean, too much timing, or a bad tune in general.

I'm making 452/431 for the last 2000 miles on my 105k mile engine. I don't DD my car, but I don't baby it when I drive it. The only issue I've had is I bent a shift fork on my stock 3650 and swapped a T56 into the car and it's been great ever since.

[32VALVR]

4 years 25k miles and probably 300 passes since going blown with no issues from the motor. A couple of diffs and tranny issues though. Also is my daily.

[SucknAir]

I beat on mine all the time on 11lbs of boost (turbo) 526/538 for 5-6 months with no problems! Got greedy and turned the boost up to 13lbs and beat on it and it hurt a cylinder after about a month. Never had it on the dyno on 13lbs but my tuner seems to thing it was in the 550+ rwhp range when it let go..... lol

[03ABMach]

A local friend of mine has a HCI Procharged mach on 6.5LBS of boost and runs it HARD .. 494hp for a few years with no issues!

[Newskool Mach]

I made 442RWHP thru a stalled auto... (Close to 500 if it was manual) 40,000 miles later and maybe 150 balls to the wall drag strip runs and it never missed a beat as a matter of fact I sold the stock short block to LOOKandGO and he is rebuilding it for another project. After the teardown it was clean as a whistle. Had 100,000 miles total on it. All in the tune and no overrevving think the automatic trans really helped. NEVER missed a shift. lol

[rcodemach1]

Never noticed any issues with mine at north of 470 rwhp. The car was going 121 mph in the quarter. This was with a non-cooled Vortech at 10 psi. But I did have some butting of the top rings. Keep in mind that the stock gap of the upper ring is around 0.011". That is way, way on the tight side for any kind of power adder. I never broke a ring land which is usually what happens when the ring ends hit, but there was some light scuffing in the upper part of a couple of the cylinders. I had it apart to do a "wellness check" and to replace some valve guides. I was able to hone the cylinders and run it (naturally aspirated for now), but it'll get new pistons and rods prior to the next power adder.

[04JUIC]

461rwhp/455rwtq with a D1SC at 10psi for over a year now, multiple 1/4 mile runs and highway runs (in mexico of course).. I use to DD it, but now its my nice day car but still not easy on it to say the least lol

nice i had 530rwhp for bout a year and a half stock bottom i started to get blow by thats about it. pistons are not gaped for boost . but it was a bad boy on the eaton surprised plenty.

[Bincky]

Stock motor all around (other than injectors and MAF). 500 rwhp / 426 rwtq for 9 years, and almost 40,000 miles. Daily driven in nice weather.

The only things I've ever had to replace included the rear-end and the clutch. The car has never broken. I've owned it since new.
