This is what drags my sorry ass down the track. Pics below...and note the absence of a WB in the DP...and a Steve Monroe TB and a Z06 MAF. Here's the rest:
Stock STD bore 109 block-Stock caps-Stock hardware
Stock STD pistons
Stock STD/STD crank
Stock rods
Stock flywheel
Stock balancer
Off the shelf Comp Cams 212/212 flat tappet cam spec'd by our very own Steve Wood. :)
NOS GM lifters-I have friends in low places. :)
Stock timing chain and gears
Balanced rotating assembly
File fit rings
8445 heads-Large valves/ported/polished by my friend/engine builder who's been at it for 30 years.
140 lb valve springs
Stock rockers with solid shafts
Upper plenum backfilled/contoured/ported/polished by my friend/engine builder
Champion stock appearing intake courtesy of IfYaGot3Yards from TBS :)
Stock headers
Stock ignition module/coil pack
6262 JB turbo matched to an Art Carr 16930 NL convertor

proof is in your pudd'n!

What's done to the plenum? Power plate?

What's done to the plenum? Power plate?
Joe backfilled/contoured it to match the intake. He also ported it for Steve Monroes TB. No Power Plate...as the plugs are evenly colored...tho I'd recommend a Power Plate for a stock upper plenum.
-
That's what I run Steve's TB with a power plate. Without a flow bench I will leave the upper plenum alone it is port matched to the throttle body.
-
Joe has a flow bench. :)

Brad, which valve springs are you using? brand and number, I mean
-
I'll shoot him a text and ask.
-
thanks

Inquiring minds would like to know
-
Comp 941 is my guess
-
Jason, I don't recommend using a heavy set of valve springs like I do. 980's and 981's will do just fine. The basic premise of this exercise is to see how fast I can go on stock junk and Erics 5.7 chip. When I hear back from Joe, I'll post up the info.
-

Steve...here's the info you requested from Joe:
130 lbs at 1.700
340 lbs at 1.250
His text didn't say what brand or part number.
-
looks like between a 981 and a 941 in comp
-
Are you running a stock intercooler as well? Also, your're using the stock nylon timing gear?

6:05 am correction from Joe this morning...lol. 130 lbs at 1.750

Cam gear is steel...and I honestly can't remember the brand. FMIC Super Extreme from TR Custom. Fit like a glove. I ran a 6.90 last year with a stretched SLIC. Only reason I swapped out to a FMIC is to keep the car more consistent for back to back runs. Keep your eyeballs peeled for a Precision stretched SLIC.
-
Or a CAS V4 SLIC
-
Dan was using a V4. I have one too. But, they flow nothing like the PTE stock location. It just shows that most people over buy stuff because they think it takes a lot more to run a number than it actually does in many cases
-
brad, are you using a stock wastegate?
-
brad, are you using a stock wastegate?
RJC 3" internally gated DP...with Jasons biggie puck...with the exhaust housing ported as far as I could take it. If Grumpy could do it with a 67...then I could do it with a 62. :) Exhaust is handled with an original ATR 3" SS dual setup with Pitbulls.
-
I tried to pattern the car after Grumpys as much as possible. Russ Merritt is Grumpys son in law...and those are Russ' wires on my car in the pic...availabl e thru RJC. :)

Ahhhh the Grumpy KISS method

Picked up a PTE SLIC second hand off the TB board about a year ago. Installed it in the car as soon as I got it.
The reason I asked about the cam gear and intercooler is that there is a laundry list of stock items that folks change out. Has someone made a checklist of all the stock items that should be replaced just for reliability? The spring cleaning thread helped me tremedously in the beginning. I know it's taken me a few years to get my car where it's at now and that involved quite a bit of time reading and searching threads. And then there's everyone's differing opinions on what is needed and what you can get by with. Then you have to make a judgement call on who to believe and who is just full of bull and who is trying to sell you something.
I do believe it's all worth it in the end... Nothing like hammering down the road in a car that you dreamed of owning when your were 16

The stock pistons will crack across the top following the line of the wrist pin in the low 10's with repeated high boost runs from the pressure. Bison had a pic in his avatar a while back of one that was cracked...with "wink" written below it. :) He also ran that 9 with the 6265 a couple weeks back...with a stock bottom end. The stock engines are durable...with no KR.
-
Jason...nothin g is indestructible . I recall Grumpy saying he broke a crank driving to the corner store...and I cracked two cylinders with moderate boost. You also have to take into consideration the parts we're using have been around since 1987...from God knows how may owners...and have likely had the living shit kicked out of them. I have everything magnufluxed... but I also know the parts are on borrowed time.
Oh, I also cracked a rocker...score d up a cylinder from a piston pin coming loose...and I also set off a sonic boom that broke windows in a 10 mile radius when I severely overboosted an engine. :)
-
If you are that worried about breaking parts, drag racing is not for you.
-
No one wants to break parts. My idea is to put together a mid to high 10 second streetable engine that can handle the abuse of daily driving and trips to the track. I've had my TR for a little over 2 years now. It's a higher mileage engine that I've put almost 14K miles and around 30 passes at the track. This is how I would be using the vehicle but I don't have that 1o second time slip yet
-
I would say real street cars ( 8 to 10,000 miles a year) that run 10's are rare. Just my opinion :cheers:
