What does it take to run under 10 seconds in the quarter?

[Grumpy]

"Chips" have come a LONG way in the last few years ... thats what we use in Melissa's 9 sec GN thats street driven almost everyday NO NOT in the snow!!!

So a stock GN tran will not hold up in the 10's? I am also new at this just trying to learn.How much money are we talking ROUGH figure to get it down in the 10's?

I think some of us on here are just concerned for your kid. What kind of experience does he have driving? I started riding mini bikes/dirt bikes when I was 4, I got my first car at 13. I had an 11 second gn when I was 24 and now I am 34 and have a low 10 second gn. My car now is stupid fast on the street and I have 34 years of common sense about when to punch it. I can see this if your kid has been racing junior dragsters since he was 8 but if not I think you should put the car to stock and give him a few years behind the wheel. Hopefully I haven't offended anyone.

like the man said. call russ

No a stock tranny will not hold up. A good 200 tranny & convertor will cost about $3500.

well my dad's Gn is 10 sec and his other is like brand new he was the first buyer and its only got 7600 miles on it (he keeps track) I just turned 22 and am fishing to buy my own,However he put like 5000 dollars into everything after he bought this one now its like 10.78 and I forgot how many mph.He wont sell it to me either ha.I guess ill buy a fixer upper and do like he did.

I could understand everyone's concerns if the title of this thread was "Gonna let my 14 year old son drive my 9 second GN on the street, good idea or bad?", but it wasn't.

I'm sorry if I gave anyone that impression but I can assure you that I am a very careful parent and will take whatever precautions are necessary to ensure everyone's safety.

Whether or not he ever gets to drive the car on his own is still three years down the roard and all I'm trying to do is have some fun getting there.

Anyway, I'm down off my soap box now so we now return you to the regularly scheduled programming...

 

[johnplogii]

What part of the country are you in? And how much work do you want to do yourself?

 

[syclone98]

I'm in Northern California and my son and I will probably do all of the work like we did with the Corvette.

We had a blast installing the mods on that car and since the GN is intended for him, I'm sure he'll get an even bigger kick out of it.

He'll get an even bigger kick out of kicking your a$$ with his Buick when you get it done if he lives long enough to do so.

Everyone knows that heads alone are only part of the equation!!!! The point I was trying to convey (that you missed) is that forced induction engines are not as sensitive to port shape or cross sectional area as a N/A. engine would be. However, a proper port shape and runner volume will aid in cylinder filling beyond what a hachet ported cylinder head will offer. Id rather make the same power through efficency and run less boost since you can not escape the effects of thermodynamics. Therefore, my statement holds true since anybody can hog out some metal but a true specialist will know WHY and how MUCH to remove.

P.s My two year old son laughs at your overdone faces in your posts.

Kenny Duttweiller is in california and really knows his stuff when it comes to the buick V6.

Gimme 20 grand, i'll build it

 

[dentmasters01]

call Jack cotton......knows everything you need to do it. I've beat on my rpe built motor for two years with only a head gasket once. Like mentioned above, the engine is only the center piece of a lot of supporting parts. If you decide to go with your 109 then you def. need good internals to "beat" on it over and over again ie steel crank, girdle, caps, rods ect.....so your not picking up parts at about 60 ft. I've got several grand in just the engine alone and then with turbo, heads, suspension, you'll spend more than you know quick. Don't forget the brakes !! Its fun to go fast, but I like stopping just as much !!:smile:

New guy!

Hello everyone, I'm looking for a little help here. Just bought an 86 LeSabre Grand Nat. Slightly better than a basket case. In need of a couple of body parts like the ribbed rear side window cover for the driver's side and a few interior parts. Anyone have some ideas for me? BTW, also have a near perfect turbo T.A. and 40K mile 85 hot air G.N. (to be converted soon). I have quite a bit of knowledge about the Regals, but looking for help on the LeSabre, Thanks in advance!

sorry guys, I meant to put this in a different thread (new guy!)

Someone who knows how to take a 109 stock block into the 9's would be Jason at RJC. Go to his website and watch his videos at BG. He can tell you from A to Z how to build a engine and drive train that will handle the abuse.
BTW - he drives his on the street. It's not an all out track car by any means.

i was just thinking the same thing ..

BOOST........and a good bit of it oh and traction helps

Tens are not just a walk in the park. Most GN's can get there with the right turbo, intercooler,fuel system,Dp and a few other things. But to make it live run after run you will need to invest all the right parts. Would I build a motor right off the bat, no. A good top end and a built trans would be a good start. I like to over build and know its safe to beat the snot out it. Parts start breaking in a bad way at those power levels. But things like a air/fuel meter should be top on the list. So much power can be gained with one and keeping it from running lean will save time and money.


Not to but into your business, but you should turn the power up slowly so your son can learn to respect a turbo car. They are very different and go from safe to out of control before you can save it.
