Default Another Guess My E.T. Post :-)

Just curious what some of the quarter mile guys think my car will do when done:

LG big breather
LS6 Intake Manifold
AFR 205 Heads
223/227 610/614 114LSA Cam
LT Headers/High Flow Cats
Coilovers
very sticky street tires...180 Tread Wear AD08's
6 Speed Manual

Should end up around 450 HP to the wheels (518 ish at the flywheel), but in a very good broad Torque curve.

Have done about 180 lbs of weight reduction too.


What do you guys think this car will be capable of in a QM?

ouch...was hoping 450 HP to the wheels would be capable of low elevens lol

maybe even high tens with the 180 lbs of weight reduction I've done...

will be a really fun daily driver regardless, the car is really set up for curvy canyon roads and an occassional weekend at road coarses...but am curious about QM capability too.

Thanks Robz....amazing machine you've got going there!

any other estimates out there?

I'm guessing. Alot of factors come into play.
Driver and traction comes to mind.
Those tires will hold you back on a average track.

thats cool...so basically with a drag pack I have a 10 second car without a 10 second driver lol

I set a budget to build the best all around car I could under for under 40k including the cost of the car.

Once the H/C are done next week, and coil overs installed this week...I'll have about $25,000 total invested, which means I can have $2,000 C6 Z06 brakes, $7,500 ECS supercharger (installed), and a hardened 3.90 rear diff $3,000 (have stock 3.42 now) installed and be at 650 RWHP and have world class road handling for under my budget...

this is getting fun :-)

Sounds like you will have a fun ride.
Keep in mind I'm just giving you my opinion and a ballpark one at that.

I didn't see a menton of the clutch?
Street tires on an average track may not hook up anywhere in low gear.
You will just have to try it.
Drag strip close to you?

Drag radials will help improve your 60'. Then with good to decent shifting I think 11.49 until the bugs and DM (driver mod) kick in.
Ok driver 11.8
Good driver 11.5
Great driver. 11.1-2
Best driver (not pro) 10.7

I'm in Orange County California...doesn't seem to be any 1/4 mile tracks left within 200 miles :-/

there is an 1/8th mile track about an hour and a half away though on an Indian Reservation.

May try to go there and see if they will let my Vert run without a bar since its only an 1/8th mile track.

Am putting an LS7 clutch in with a new slave and remote bleeder with H/C install next week.

Whats your car run Ron?

I thought I saw a post saying that your cam was a similar spec as mine...what heads are you running?

Hey Steven,

My cam is similar. 226/230 .609/.597 114+3 by Pat G (EPS). So their lobes. I also have the AFR205 heads. Fast 102, 90mm TB, headers etc.
I'm an A4, so MUCH easier to race than a stick.
No clue on power.

Best so far is 11.10 @ just shy of 123. Drag radials of course. On street rubber, the best I got was a 12.0, but i gave up on that pretty early on.

Your car will be very strong with that setup.
