Roastem's Z28, FINAL numbers

[Roastem]

I am about modded out fellas. Don't plan on nitrous or a blower, and I will put a stroker engine in it if this one ever goes, but this is prolly my last improvements for a while.

Pre-Moser numbers: 404 whp/392 tq
(stock rear, 4.10 gears, 02 sensors not hooked up, very lean 16:1)

3.73 Moser numbers TODAY (Carolina Auto Masters): 412 whp/394 tq
(fourth gear 130 mph @ 6800 rpm, 12.8:1 ratio)

We all expected the car to make less power since I didn't have any power mods since the first dyno. Just weight loss and a rear swap.

I am pleasantly surprised I didn't lose horses after the rear swap. Maybe the 02 sensor had something to do with the pre-Moser run numbers. Anyway, she is running good now and its time for a 1/4 mile slip!

nice numbers I would still love to see your car run!

[mpeyton]

what mods got you to those numbers?

[Roastem]

I saw your numbers too dude, NICE! Your mustang is out of my league now, but I will still run ya!

I need to go to Rockingham dragway for a 1/4 time, you know when they will be running down there again?

[Roastem]

what mods got you to those numbers?

Ported and polished LS6 heads
titanium valve spring retainers
Comp 918 valve springs
Comp cam 224 duration 568 lift
Meziere electric pump
LS6 intake
Port & polished throttle body
Free mods
SLP long tubes, with catless Y
Hooker Aerochamber catback
A/C delete (it was worth something I am sure)

Those are the only things I can think of off the top. I am sure I missed something.

[shady milkman]

so UD pullies and alt. pulleys ? or port the ls6? i'm just curious on why you are all modded out?

[Roastem]

Port the intake? I don't know if it will be worth the trouble. Pulleys, well I haven't tried that yet. Maybe since I only have the head unit and four satellite speakers, I don't have to worry about the alternator not putting out enough power due to the slower rotation of the pulley.

I just might look into some U/D pulleys shady.

yea and with the alternator pulleys it evens everything out..if the car was a DD then the power steering would be an issue..since it is belt driven but yea get some ud/alternator pulleys and might net you some more. i dont know about the ls6..but the fast 90/90 shows a very solid increase when ported.ups of 10rwhp+

I dont know for sure but i can always check their website. If you ever ride to the charlotte or concord area let me know! btw, y buddy sold his z06 and got a c6 vette. Its was a little slower!

[Roastem]

I bet, you run that Z06 before he sold it? Against the charged stang?

Damn son, that intake is about a 1000 dollars ain't it?

[shady milkman]

yup. the new 92/92 are out..and i guess they flow 15% more then 90/90

no we never raced after i got the work done. We were close b4 the work after it would have been bad!

[Roastem]

You got a slip on the Mach 1 yet?

[BULLET_WS6]

they dont flow any diff... have the same intake runner... they were just redesigned to fit better... you can check the website... the change was not done for more power
wait... was that sarcasm

well by nature the larger the tb the less turbulent the air which is good...but you already know that man..i'm just saying i am sure it will improve numbers..especially the nitrous boys/girls..the new design(material) is supposed to handle the pill alot better.

yes it was sarcasm..i take all "new" dyno estimates are bs...almost as much as slp's numbers are
