Im about to purchase a lighting with 43000 miles and i was wondering what all does it take to get a lightning to or over 400rwhp.

I was thinking 4# lower, longtubes, CAI, larger single blade thorttle body, aftermarket plenum, sct big mass air meter, Boost A Pump and a boost bypass kit. And a costume tune.

What do yall think??

 

ported eaton, ported or high flow upper plenium, 6# lower, valve body, long tubes, custom tune and a better heat exchanger should have you close

forget the boost bypass the tune will take care of that

don't forget the plugs and a MAF or MAFia

 

If you take your list minus the boost bypass and Tarajerame's longtubes suggestion, it is all you need to get just over 400rwhp on a 2001+ lightning. I get about 400 even with that on my 2000 and I've got the smaller intakes.

I'm running:
Mild JDM tune
4# pulley
SB throttle body
custom plenum
CAI
JBM longtubes+exhaust
90mm MAF (stock on 2001+)

and I'm 392rwhp on a hot day.

 

^^^^^^^^^^^^^^^

Agreed. I'm almost at 390 on a hot day and stock blower. Dyno tune is a huge help with a good tuner.

 

Yeah, the difference between the two runs there in my chart are merely the stock ECU and JDM's tune. That's a pump gas mild tune.

 

16 degrees timing, A/F ratio in the low 11's, and the below mods in the sig has gotten me 437RWHP & 447RWHP on different days on different dynos in cooler (for Miami) weather.

 

Well got it dynoed today at made 415hp 499lbs. 55 degress outside today.

lfp longtubes, lfp plenum and throttle body, 5lb lower, jlp cai, sct big mass air. boost a pump, jlp power cooler and Double pass heat exchanger.


Porting and Heads/cams will come soon!!

 

I believe a good port on the Eaton will get you another 20 RWHP or possibly a little more. Also consider the 6 pound lower.

 

sweet. i think im gonna wait on the performance parts for a while and get a 3200 stall.

 

Good move on the stall.

 

personally id suggest a custom tune over a costume tune.

 

how expensive is it to port and polish a supercharger and plenum?? or is it just worth it to buy a jlp plenum... i have roughly 10 G to install my L motor into my f150 and somewhat fix it up and i wanna get the most out of it with what i got.

 

Port & Polish is good bang for the buck on the blower (only) through Steigemeier (SP). On the Plenum, whether you port a factory one or buy aftermarket has almost no gain, just as headers on an otherwise stock truck. If that $10k is for mods, I would look into a Kenne Bell blower.

 

i already know about the kb blowers and i've seen the damage they do i will get one eventually but the 10k is for the motor swap and minor performance upgrades but the rest of the money is going to a new paintjob and complete body overhaul
also, i asked how much the superhcarger porting would cost through steigemeir

 

Jughead- it should run about $200-250 for a plenum port. I know you can buy a new one already ported for prolly the same amount of $$. Steigemeir is about 3hrs from me. I have talked to a couple of guys from my area (Warrensburg, Mo.) and they said Steig is the way to go.
