Grand National times possible

[IThinkImFast]

Hi,
just wondering if we could ever see the times in the 1/4 like the top GN cars [img]graemlins/burnout.gif[/img] see. Well i guess a turbo kit would have to come out first, but if it does would it be possible with forged internals? And valentines day is the worlds most god aweful created holiday ever!!!!!

Well the GN cars are setup totally different then ours. I think a strong 3.8 with forged internals and a turbo could be very fast. But I dont know anybody that has done it yet. A stock GN is fast but not that fast. But they are very easy to mod and make go fast. I have seen GN's run 8's in vegas. If your asking if your car can every run 8's with a turbo, probly not.

[SLOWBRAEATER]

I disagree, with the right amount of money a 3.8 fbody can see 8s with a turbo, ALOT of money though

[IThinkImFast]

what about a decently moded Supra TT or one big turbo....if we had a kit could we run with them?

I think that alot of the deal with GN's are they were just so darn well built.. motor wise that is.. also from what I understand those really bad GN's with crazy 1/4 times aren't exactly streetable..

I think if you built up the motor with the strongest stuff you could find within some kind of reason and managed to put enough boost into it, then yeah you'd have the power to make it to some low numbers but you'd be running some kind of super high octane race gas, and such a funky compression that your power would make the car pretty unstreetable, still if you had the power to throw down some really low numbers the rest of the drivetrain has to hold up to the beating..

Anything is possible if you spend your money in the right place and actually research and be knowledgeable about what you are doing.

Our blocks are stronger than GN blocks, our crank and rods and pistons need replacement depending on the duty if you're going to extremes.

supra will probly beau u out, just cuz of 4v per cylinder, lighter block and head, and just overall design of the engines make them better. but, i'd love 2 see someone prove me wrong about this :D

The GN (turbo) blocks aren't any different than the normally aspirated 86-87 V6 blocks available in the cheap Regal. The same goes for the rods and heads, while the crank comes from the 4.1L V6 out of mom's old Estate Wagon. The blocks use only 2-bolt cast mains and have a 1/2" hole drilled in a boss that is precast into the front of the block to allow for the turbo oil drain line. It's not so much a block strength issue as a lack of headbolt count; with only 8 head bolts in the stock configuration the real challenge is keeping head gaskets in the vehicle when dipping into the mid 10-second range. Tuning becomes very important, yes it does. In my case, the motor coming together for my GN uses a stock block with a 3/4" plate steel girdle and steel mains.

With some work we've seen a few individuals crack the 9's on stock block & rods, ported heads and in some cases a steel crank. But, durability becomes a factor at that power level, so most step up to a Stage motor (thicker block webbing, better main caps, 14-headbolt configuration, etc.) at that point.

Hey Morgan, you're from Yorba Linda. I'm from Corona. Cool, were almost neighbor. Sorry I didn't mean to go off the post.

According to the January issue of Hemming's Rods and Perf. #15 that the block they used for forced induction was the same block in 1978. I believe ours is no different. Ofcourse the issue of oil problem is no longer a case for our engine. Forging the internals and lowering the compression to 8:1 would make it a good candidate for high boost such as 15-20psi. Our stock engine can handle up to 9psi and with that we are well over 330hp (with just that). And yet still be safe. Ofcourse we have to deal with blow by.

Our 3800-II's run crossbolted 4bolt main blocks, however the nodular iron crank might eventually be a weak point for us.

What do 600, 700, and 800HP Supra's have in common?

This is one of the first questions I asked when I joined this board.
Why hasn't anybody taken the GNX approach to building an F-body?

I think one is the cost involved, the V-6 F-body has always been the little fat kid everybody picked on. So nobody ever bothered.

I once was told "you know what the best thing about the v6 in a firebird is?" A V-8 fits in the same place.

Popular mentality has always been why build a six when you can build an 8?

The GN/GNX was different, it was factory fast, a family car, and developed a loyal following of hot roders who needed a fast family car.

I think it is just a matter of time before somebody does apply the turbo Buick philosophy to a v6 f-body, then watch out.

I have to believe that an F-body with the same motor/trany/rear combo as a GNX would be faster due the CD factor.
