Most successful built seven bolts?

[UncleBens]

You always here about 6 bolt swaps and crankwalk on 7 bolts. Are there any real success stories out there for built 7 bolts? I'm talking about a fast (like 11's and better) 2g with a built 7 bolt that has gone at least 15,000 miles or more and is still running strong with no crankwalk issues.

Im not sure if you would count this but I believe Russ Coxe has a built up 7bolt and is running 9s in his 2g Automatic Red GSX.

 

[KPWSerpiente]

People have run 11's on the stock 7 bolt. You might be next.

Guys on the DSMlink boards have pushed 36psi and 500whp out of stock bottom end 7bolts. I remember one guy pushing 11.4 on pump gas out of one. If your setup is right, IE not a ### Safc, then the 7bolt can go a good while in the right hands.

Well I don't have a heavily modified 7-bolt internal wise but I do have a lot of bolt ons and run around 18 pounds. I have around 105,000 miles and can still roast the tires. Other than replacing the maintenance stuff it runs just as strong as when it was new.

Hopefully my 7 bolt will be remembered as a succesful one. I just had it rebuilt eagle rods, wiseco 8.5, b/s removed, oil squirters removed, new spec thrust. I did my research and hopefully it will pay off. Good Luck to all my 7 bolt brothers.

i have been on my built 7 bolt for a year now with no problems

Paul S has a fully built 7 bolt that ran a couple of 11's last summer.

 

[Red97Eclipseboy]

Yeah, 7-bolts can hold their own. Mine started walking at 45,000 when it was bone stock and it went all the way to 94,000... and still nothing happened from the crankwalk. Got me a 6-bolt now, though!

 

[Steve93Talon]

I've gone 11.9 on a bone stock 7 bolt and a Green, my friend Scott has also gone 11.9 with a 20g. Both cars were '93 Talons, full weight, stock cams on full 2.5". Jim McKeone has gone 11.5 on a stock 7 bolt, Green, lightened car, stock cams, 3". Tort9320g has gone 11.05 on a bone stock 134k 7 bolt as well. These are all 1G cars, but aside from the crankwalk issues, a 2G bottom end should be capable of the same numbers.

 

[1fast97gsx]

I ran a built 7 bolt last summer which would have ran in the 11s for sure if I wouild have ever made it to the track. ( broke 2 trannies before I went to the track on 2 occasions ) I was using ross pistons and eagle rods.

 

[Turbo Monk3y]

Well i had my stock 7bolt last season that started walking by breaking 2 crank angle sensors, but i kept racing it on basic bolt ons and 20 psi with race gas and small 16g i managed a 12.9 at 105 last season... I sold the motor to some guy for 650 told him that i knew it had crankwalk and he said something about every motor has crankwalk lalala i mean i didnt care since i got 650 for it. But now i have new 6 bolt but surprisingly i see that guy driving around in his automatic gsx every now and then with my old 7 bolt in it still running good...

 

[GSX4LIFE]

I originally started with a horror story thanks to Extreme Motorsports. But after having it redone, It has been fine for almost 3 years and about 30,000 miles, including a 2500mile move from Pa to AZ last summer. It has Eagle rods, venolia pistons. No balance shafts. My times arent very impressive, but it does trap over 120 with a beat tranny. And it's still going strong. Hell, I just recently replaced the head hasket that was done with the rebuild 2.5 years ago. It was a stock mitsu(thanks again Glazer).

 

[illeagle_talon]

Tort's talon probabaly the sickest 7 bolt I know of. 7 bolt, internal gate 20g, runnin' 11 seconds dead. Hell of a car. Don't take my word for it though.....

[BacknBlack92ESi]

A friends 2Gb GSX ran consistant 12.0's on the stock 7-bolt bottom end. It can be done. And alot of people have done it. I will be the next

 

[TurboSpoolinIns]

"ecoli" on here has a built 7 bolt 2.4L and has gone a best ET of 10.4 and a best mph of 138 mph. On the 10.4 run, the motor held together, but 4th gear decided to destroy itself hence the low mph(130).

Crankwalk is so overrated. Everytime someone has any problem with a 7 bolt they are quick to blame crankwalk and go running for a 6 bolt. :Sigh

Good luck 7 bolt people out there.

What? Yeah... everytime something goes wrong people blame crank walk. Either you have it or you don't... so if you don't, how can you blame it? I've never seen anyone on here blame something on crank walk when their car wasn't walking. Oh, and unless you have had crankwalk, please stop saying that crank walk "overrated". After the hassles of my motor walking and all this shit, it's a bi*** and a big hole in the wallet. Gee, I wonder why people who have a 7-bolt that walks, go for a 6-bolt? I hope you're not that stupid. Slowboy, Diamondstarmotor, etc... don't even like to touch 7-bolts. They recomend right in their site for 2g guys to use 6-bolts for, my I quote, "crank walk assurance". What do they know? I guess 6-bolts are "overrated". :::sigh:::

I built my 7-bolt and i never had a problem with crankwalk...however i did build it with the MBCAD (main bearing cap alignment dowel) kit from mach v motorsports to help prevent this. We made consistent 550+whp runs on this setup, and is used as my daily driver. I put close to 3,000 hard driven miles on the motor, never without a problem.....then one day my crank dampener decided to separate causing belts to break..eventually catching the timing belt and jump time.....result....pistons whackin the valves and about 4000 grand in damage.......but once again this could have also happen in a 6 bolt.........by the way guys...does anyone make fluid dampeners for our car.......im also rebuilding my 7bolt back to the way it was...check my profile if your interested in my particular mods

Did you ever use the MBCAD kit on a previously walking car after a rebuild?

 

[Da Dymer]

when i rebuilt my car for the first time....it was due to my stupid ass running 30psi on the stock t28 on 93 octane...basically fried the pistons...but there was no sign of crankwalk......for the record i also used an act 2900 6puck disc...and that should be a healthy candidate for crankwalk...but yet....i have never came across that issue...even after a few dozen 6500rpm launches at 31psi with my garret....im a strong believer that the MBCAD kit is worth every penny....cheap insurance anyway

Yeah, I don't know how I feel about that kit. Most people say it might help, but it's not a 'for sure' thing. The only reason I ask is because I have a machined 7-bolt in my basement I was going to use with the CAD kit in there, but I was just too weary about it. I got a full 6-bolt with intake mani and everything I need for a 2g swap for $250... so I'm going to play it safe. I can still use the 7-bolt, but I just haven't heard any real convincing stories about the CAD it. Yours would be great if you had these results if you were previously walking.

True..its def not a "for sure" thing.....id prefer a 6-bolt myself, but im short on cash, so im just goin to rebuild my 7-bolt, (avoiding the expense of the swap kit from slow boy)...hoping it holds up like it has.....by the way...do they make fluid dampeners for our cars.....i dont wanna risk another oem one..and having this happen again

Actually come to think of it...when i rebuilt my motor...the bearing were a little out of spec, and we replaced the crank sensor...also prior to the rebuild...my clutch pedal would stick a little while making turns......but these were all problems prior to putting the MBCAD kit in...i never had a problem with the clutch or crank sensor after the rebuild ...durring the rebuild, i did get a new oem crank (just for the hell of it..spare laying around) and all new clevite bearings
