I've searched and searched for le1 h/c track times and haven't found any. So i was wondering what you guys were running. My goal is 11's.

 

It would take MAJOR weight reductions for the average LE1 LT1 with required upgrades to hit 11's. Not gonna happen on the average car w/o power adder. LE2 is much more able to hit 11's.

 

There were a cpl of guys running 11.6/11.7 (Skinnies with BRE LE1 cam, T/A LT1 with older Joe O LE1 cam) but they had a4 cars with good converters cutting 1.59-1.62 60 fts and they had 58 MM TB, 1 3/4 headers, good exhaust, etc.

The average 3700 lb 6 speed car getting 2.0 60 fts are gonna be in the mid to low 12's.

Ugh... I just don't get that.

I went consistent bottom 12's with multiple 12.0's with just a bitty cc503 cam in a full weight full option Z28 back in 2003.... why wouldn't a heads/cam car be able to hit at least high 11's consistently?

 

there was a thread about the fastest le2 a week or 2 ago. I think it was bottom 11's. But most were mid 11's @ 117-120. Id say most le1's are good for bottom 12's to high 11's. A4 cars with 3.73's and a 3600 stalls are different as they are setup for drag racing. But your average m6 guy with 3.73's or 4.10's will have a hard time getting into the 11's, unless his car has some qa1's(or other drag shocks), 12 bolt, etc.

 

Another thing to think about is that a lot of guys getting the LE1 don't drag race. They just want a fun/fast street car. If drag racing is a primary concern then more than likely the LE1 isn't going to be your first choice anyway.

 

i like to drag race as a hobby not a sport and i have stock h/c... i would LOVE to have the LE1 heads with the 227 cam that i am installing but i'm a poor fellow...

le1 with cam and all the other bolt-ons would put you around 370-390 rwhp...
i could definently see a a4 with a 3k stall and dr's going 11.9xx on a good day but i don't think it would be consistent...

 

I know what the LE1 is capable of, look at my sig, but I'm just saying if drag racing is your primary concern for upgrading to a H/C setup then more than likely you want something more than a LE1, most people don't daily drive their drag car. You drag as a hobby and I see that you went with an even smaller, though proven, cam than the LE1. That's my point.

 

I'd say 370 rwhp max with an M6 car and the 227. Probably more like 350-370.

 

i meant the le1 cam... sorry for the confusion... i'm hoping for 340 rwhp. would that put me at 400 at the motor?

 

Notice I was implying that the "average" LE1 package would have it hard to hit the 11's. That's not a knock on the LE1 at all which will be banging low mid 12's in street trim like clockwork. Now throw in a power adder or weight reductions then things change.

11's consistent requires a bit more cam and overall power IMHO. Sure you can get the right weather, dead hook, tailwind and position of the moon etc. and tap an occasional high 11. But occasional 11's and consistent 11's are two different things.

 

Well i guess my primary concern would be a high 11 second street car. My reason for going LE1 is there obviously is alot of power there, look at ulakovic22 numbers. I would think that by taking the money that i would save from going LE1 to LE2 and putting that money towards suspension and a stronger rearend, high 11's would then be in the hands of me driving it well enough.

 

I think it's funny that people talk about full weight full bolt ons hitting mid 12s easy. Then add a cam AND heads and only go a couple tenths faster!? I don't buy it. LE1s should hit 11s.

 

Who has a full weight and full bolt on lt1 running mid 12's??? i'll buy it!

Edit: i could see someone from a drier cooler climate maybe getting there with full bolt ons, full wieght and with 3600 stall, slicks and 4:11's... and when i think mid 12 i think 12.4-12.6...

 

I had near full bolt-on LT1 before I did my new LE motor. I did not have electric water pump or long tube headers, however my headers are still 1.75 primary and are not shorties.

Best ET I got on a full weight vert was 13.2 in the 1/4" on street tires. I have read where some are hittting mid 12's on full bolt on but I am having a hard time belieiving it on a full weight car. Sorry.
