Just a well put together package. The heads I used were N/A heads so that might of helped a little. Instead on looking for crazy CFM numbers we capitalized on the lift that the cams had (.473) and made the heads flow very well for the low lift cams we have. I learned that for whatever reason my car loved to run really rich on the Q16 and that picked up a decent amount by itself. The other thing we focused on was keeping the IAT's as cold as possible for each pass. I would drop .3 on my 3rd pass just because the 20lbs of ice would be melted and the water would be like warm by then.

Ok well leave your car stock, add drag radials and you could run 11.7 with no modifications except drag radials.

You see how crazy that sounds.... If you want to go sorta fast add Kleemann mid headers, a 168-175 crankshaft pulley, split the cooling and add a tank up front for extra cooling capacity, a set of k&n filters and a really good road tune or atleast a dyno tune. That setup should be good for 11.3-11.6 @121-123 depending on driver, track prep, and DA

Hammer Down

The numbers that we achieved may not be the numbers you achieve with same mods. All cars on the list trap between 127-133. All different setups, lightweight wheels & breaks, no interior with racing seat, no rear exhaust, just drag radials only, lightweight battery, 180lb driver to 250lb+ driver

The only way to find out if your car will run 10's is to run it. When my buddy got out of my car when I took him for a ride after i modded it he said man that really surprised me, I'm impressed. I then said yeah it's a 10sec car and he said have you run 10 seconds yet? I said no not yet he replied, well then it's not a 10 sec car until you run it. My setup is really similar to Hulk's and he ran 11.1

Why could the NA heads have helped? Maybe a smaller quench in the combustion chamber for higher compression and or milling of the heads is my guess.

Nice work on the optimizing your airflow for the stock cam lift. The fuel thing sounds good too. C16 sounds like overkill for our motors, especially with stock internals. MS109 sounds good though.

All makes perfect sense. Icing down the supercharger and keeping your trunk tank ice cold has always been one of the main keys for our cars to run the lowest numbers at the track.

Maybe some weight reduction wouldn't hurt either. Thanks for sharing!

Hulk

Your buddy is a real assh0le lol, no but seriously, like you said many factors can come into play with times and mph, so just because you have someone's exact setup doesn't mean you will run the same

Hulk

I have never tried Q16, I just don't like leaded fuel. That's my opinion, look at lowpro he ran with MS109 and did very well.

Hotsauce55

I hear you but your missing the point of the recommendation. Its to give people a general idea of what it takes to run in those time brackets. Its not an exact science and will never cover off every combo, track variable or driver variable etc... It would also put a stop to a number of basic performance questions that everyone new to the platform has. Your thoughts on what it takes for 11.3 to 11.6 is perfect for reference of roughly what it takes! Again just a general gauge for folks, wont cover off every variable or environment.

I know right? He's old school big block chevy guy but he was right and the pressure was on me.

The N/A heads were only decked for flatness so we didn't really change the CC's of the chamber. The chambers are the same in both heads. The N/A head doesn't have the hump in the intake and my porter tested both and said hands down the N/A head was better for what I was trying to do. The exhaust port is also a tiny bit different where the EGR ports are. I went with Q16 for safety and it has 10% oxygen compared to MS109's 9%. As long as you can keep IAT's down q16 is great. There was a lot of other little things I did to the car but I can't let all my secrets out

How much you want for that built motor Chris has waiting for you?

dllhg

I copied Hammerdown's mods more or less. Only thing I see missing is Killer Chiller and or Methonal. For daily driving you cant beat them on these cars or any FI car for that matter. Nothing worse than losing 50+ WHP from a heat soaked car. also I'll add it seems looped rails are not needed nor do they even help on these cars. Doesn't RBJ still run stock rails even with all the power he is putting down ? I opted not to installed them after many very reputable and very fast members told me not to bother. Two years and 20K miles later beating the crap out of her seems to prove they were right.

Max.H

Nice, if opportunity arrises I would definitely raise compression. I understand where you are coming from. Oddly I thought some lighter fuels had more oxygenation. True indeed, A lot of a little adds up. Little debarring here. Little smoothening there. Little weight reduction here little there. LoL

Hey you are a good sport! 10.5 is solid.

Whats up with your GT500??? I demand to see pics of that beast!!

LOLLSX

I know numbers don't mean anything. My stock 55k has ran c63 507 and a s65. Both make more power. Both should beat me and do so on paper. Both saw tail lights the entire time. But number help judge what mods to do for what power and where to start. I like to know what other people have gotten out of something before I pay for it. If that makes sense

Hammer Down

What's your goal?

e500slr

That's 760 crank HP. E55s lose 18% through the drivetrain.

By the way are headers absolutely necessary for 10s?

Hulk

I got to 11.1 with modded stock manifolds
I think with a better 60' it would have been 10s however with completely stock manifolds I don't think it's possible.

LOLLSX

My goal is 600-650hp on motor. But then again power aside I would be happy with low to mid 11's on the motor. I will add some spray to dip into the 10's but that wont be for a while.

What is this hump in the intake port for?

Hammer Down

You can add Kleemann mid headers, a 168-175 crankshaft pulley, split the cooling and add a tank up front for extra cooling capacity, a set of k&n filters and a really good road tune or atleast a dyno tune. That setup should be good for 11.3-11.6 @121-123 depending on driver, track prep, and DA if you want to go faster you will have to upgrade to a 82mm TB, upgrade your injectors and increase your crankshaft pulley size and retune

rawdvm

This is my list of mods:

EC 84mmS/C pulley
Belt-wrap kit & ASP pulleys
EC 550cc injectors (stock fuel rail)
EC 82mm TB
EC Heat Exchanger
NGK LFR7AIX plugs
AFE Pro Dry S filters
Wrapped, custom mid-length headers , no cats, x-pipe, no resonator (stock mufflers for now - looking at electric cut-outs & other mufflers)
EC Ported/polished heads (stock cams)
Weistec 170mm Modular CP
EC trunk tank (Dad's)
EC built transmission, 3K converter & TCU tune
Quaife LSD
EC dyno tune
548whp/610wtq (93 octane) on Jerry's new DynoJet 424XLC2 with the linx system (front & rear rollers linked together)

She is my daily driver. I haven't tracked her, yet, so, I don't have times to compare with the others here. But, she's strong.

e500slr

Easy 10 sec car.

Hammer Down

Looks good now just get that beast to the track and join the club

mobhouse

Damn that's crazy! I pushed out 490whp/544wtq on his new dyno. That thing is awesome!
