Hey all, just wanted to share a sweet build we wrapped up today.



2013 Manual ZL1, came in at 536 rwhp & 521 ft/lbs tq (he already had a cold air intake and a larger bottom pulley, no tuning). He was looking to pick up a lot more power, and also do a few exterior modifications to change the look of the car.

While we knew we wanted to go big on this build, we were not willing to sacrifice any driveability. Tame drivers with great low and mid range power are important to us, and this build was nothing different in that department. We used our ZL-Win cam, which is a 221/243 .60x/.62x cam on a 116 LSA. We also sent off the LSA cylinder heads to none other than Phil at Advanced Induction, for his full port & polish work, and to be topped off with a set of Brian Tooley Platinum valve springs. We went with our usual Kooks header set up - as they consistently perform as expected, and fit very well also. To help out with a few more horses, we also utilized a VMAX ported and polished throttle body.



We also added a larger crank pulley, and the 10 bolt interchangeable hub on the blower snout with a 2.55" upper. This, like just about every other ZL we've seen, already had the issue where the stock damper spring was biting in, so we replaced that with Lingenfelter's solid coupling. We also swapped out the cold air intake that he had for a Roto Fab.



Also, we picked up Lingenfelter's massive heat exchanger, with fans - and also a larger reservoir. These items were very big in keeping the IAT's nice and cool, he'll really need that come summertime as it gets pretty darn hot here.



We also lowered it 1" while it was here, with BMR springs. Very nice riding car. Looks-wise, we added some goodies from Oracle. He wanted the colorshift Halos, and also some front grille lighting and under hood lighting. Topped it off with a lighted rear bowtie which looked pretty neat IMO.







He also wanted to add gauges, so I used my go-to Autometers, wideband & boost. We also did another one right above the steering column, along with a raptor shift light.



Our final results were 761 rwhp & 737 ft/lbs tq. Not bad for a car that drives like a stocker.

 

Whoops, left out the videos!

 

I wish...

 

Oh man, dat torque

 

Nice !!!

Port the blower snout

 

So, other than the ported throttle body, the snout and blower case were completely stock? Not even port matching to the ported heads?

 

Is this on straight 93 octane?....or e85? Meth?

 

Correct, no porting aside from throttle body. Not that I think the porting would have been a waste, but the blower is the limiting factor here and the customer will likely be doing a Whipple later this year anyway.

93 octane only. No meth.

 

DAYYYYUUUMMMM!!!!!!

Advanced Induction is AWESOME!!! They CNC port and polished my heads on my LQ9 build! Looking forward to seeing how much of an imporvement in May sometime when the car gets built!

 

Great numbers and work I love these cars.
How much boost?

 

Beautiful!

 

WOW , that's the highest HP from stock bottom and blower on lsa I've ever seen.

Great work , i bet you'll gain some power from porting the snout and matching the heads .

 

I sure hope I get to experience 700 lbs. of torque @ 3,000 rpm before I take my last breath

I can't imagine the rush once the tires hook up...great results, Alvin!

 

About 17lbs

Yeah, next on his list is a set of drag radials. With the stock tires it just gets sideways so fast!

 

Alvin,
Great results. Thanks for sharing.

 

seems like allot of power gain for the mods listed, especially with zero porting.

wonder why it didnt get posted over on the V forum....

 

That is a huge gain.

 

How are the iat's? I'd add meth injection on any FI setup but especially one with a pd blower.

 

Those are some sweet gains!!! Congrats!!

 

Damn thats nice!!
