Bunker.... kick *** numbers!


Bunker has the old LE3 cam.... the thing is a MONSTER of a cam. A guy should be posting numbers up soon on a LE1 head, LE2.1 cam and 355 combo that make almost that HP and Better TQ. Actually these are the best numbers i've seen on a head/cam package using stock valves!.... but dyno numbers only count if you are on the same dyno with the same tranny. The newer cams are more streetable because they have more low and mid range TQ.

BOTH setups are done the right way, all the right supporting mods and everything working together.

Kory, The new LE2 cam will peak around 6300-6400 and makes a good aggressive street cam. It's very streetable.

RealQuick.... It's true that the better cams help make more power over a "off the shelf" the real key with something like Lloyds setups is that I work a lot with him to match the cam to his porting. We have worked the LE cams out for months now tweaking them and getting little gains here and there in HP, TQ and drivability. The key I feel is getting the heads and cam to match the setups they go in. You can now get a LE cam for anything from being emissions legal to a LE3 383 cam and that's a matched setup. He can also do a custom for a solid roller, TFS, LT4, AFR, 396 etc... combination.

The matched LE cams REALLY have been working awesome with his heads. This is vs. something like a cc-306, GM847 or some CMS cam. You COULD see good numbers with one of those but we are working on better valve control for more power at high RPM, much more mid range and good drivability considering how aggressive the specs on these cams are. I've very happy with the results on these setups.

for how big the cam is, id say its streetable but you have to learn how to drive it and you need a GOOD tune. 4.10 gears help out as well. but bunker is using 3.73s i think he gets about 300 kms per tank on that cam, and thats not highway.

 

Awsome numbers man...i would love to have an le setup, ill just be saving for a long time.

Hey Bunker, very nice!

Now get in there and do some tuning. As Rooster said, you're leaving more than a few ponies behind.

Nice to have a strong combination cause then you can concentrate on tweaking what you have.

Best of luck.

What kind of flow number did you get from the heads? Also, what are the specs on the cam?

Good numbers though!!!

 

Ah the old cam spec question... It's not one of mine but that puppy is BIG

 

Very nice numbers. I cant wait to see what i can do with the 383 and a shot of nitrous

 

I know how underguessing your setup is. I could have gotten a few more out of my personal car but it did about 40 more than we expected and i was on the dyno for free. (i'd almost rather pay for it so i don't feel bad for using up alot of time)

 

damn thats going through a 12 bolt, awesome numbers

 

Thanx guys, sorry for the delay on the dyno graph its coming.

Gonna answer a few questsions now:

The cam is streetable, I drive the car almost every day, you have to keep in mind that its not a stock cam and you'll be fine. Out of all the cams I drove anything past cc306 feel the same to me LOL, this thing although I can't give out the specs unless Lloyd doesn't care since its the older version I will. It actually has more power down low then the GM 847 did, the idle is pretty nice and it almost passed emissions LOL.

HC = 0.74 Pass is 0.50 4 years ago pass was 0.75. CO/NOX was super low.

Anyways, yeah I saw the other post making 415rwhp which is awesome, I think its pretty equal to my numbers considering he's got a 355 while I have a stock 350 bottom end.

Yes I was amazed all this through a 12 bolt LOL. Thing is I've been tunning some LS1's lately and the upload time for a tune being 27 second vs. 5 mins for us, I don't know if I can stand tunning OBDI's anymore LOL.

My next step is OBDII conversion to speed up upload times, I think I can get a few more ponnies out of her, not too much more but more. Also when you make that kind of power you love the setup so much you feel bad running her hard, then again I rev her to 7k all the time but she peaks at around 6500 rpm and carries it through.

The heads flowed 267.9/197.0 @.600 lift, Lloyd asked me if I wanted to race my flow sheet or if I wanted to make some power, good thing I said power LOL.

I love this guys, recently the LS1s started making us look bad so I was extatic when I saw the numbers.

Whats next? 10 bolt Just joking. Also I'm super impressed by the TQ numbers as well, thats LS1 teretory I'm walking for TQ, maybe I should switch out that tiny MOROSO CAI next time as well.

Anyways as you guys can see keep talking I still can't get over it

 

I think OBDII is a mistake in highly modified LT1's - there's a reason why most OBDII guys swap to OBDI.

 

I'm pretty good at tunning it shouldn't be any different then tunning LS1s, to me I want more options

 

OBD2s don't upload as fast as LS1s. They are quicker but not by a whole lot. At least not enough to justify converting to OBD2. You might make a few HP less with the OBD2 as well and you will need to re-do your WOT air fuel ratio.
There are no more options in the OBD2 either and it's not closer to tuning an LS1. It's pretty much the same as OBD1 with a few differences.

Are you running a 58mm TB by the way?

 

Awesome Numbers!

 

Great numbers!
