Fastest stock unopened motor

[Dusty Bradford]

That car hits it pretty good down low.

I was under the impression that a large turbo such as the 64 66 and larger was too big to run on a completely stock head(no port work) ?

Well, im sure with your setup, a tad more times to the track and it will surpass stangbangers 10.66 , and you have already passed Tim Stockwells runs :biggrin:

Keep us posted on how well it does in the near future.

The only problem so far is matching a non lock torque converter to this turbo size with the stock engine. It makes so much power down low and can't turn enough rpm to really lock in. The car might actually go faster with a smaller turbo or a ball bearing set-up so I could tighten the converter up. It's not an ideal combo, I can say that. Laz will figure out a way though to put the #'s down.

What's everyone's opinion on how much the stock bottom end can handle without any detonation?

I think mid-high tens for a pretty good period of time before the caps move around enough to cause problems.

Dusty, apparently those convertors work great, and i totally agree once its all said and done, the top end will match that 60'

Makes me want to break out the wallet for a non lockup convertor just to compare against my stock D5 in the white car in my signature.

I'm still around. My numbers and combo posted above were right......except for the boost. It was over 35. Don't really know, as that's all the gauge shows.

 

[daturbosix]

reviving this old thread... anyone into the 9s yet on unopened engine?

Well we are still kicking we got a new low mileage car to work with and new times . Rico bought a nice car and we been trying to help the cause best so far is 10.62 the D.A was 2600 when we got there it did improve . The torque convertor is too loose so we need some updates to tackle it any further .

We did dyno this car peak tq 550 @ 3900 538@4800 falls off a cliff after that .

 

[Marty Fairchild]

Can you give us a list of your mods?
Also fuel type,timing and boost?
Thanks in advance.

 

[laz]

Marty would you like the lotto numbers also ? To make this combo work you gotta push it so its aggressive c 16 32 lbs of boost , its alot easier to put some more bolt ons makes it easier .

Motivation time to clean up the cobwebs and get to work . I could see the lock up being worth while on this combo our is non lock and not in its range . We will be back out in 2 weeks and try and update the list .

 

[achalmersman]

Wow these guys trapped 130 on stock cam& stock unported heads? Has to be racing fuel and upwards of 40 psi right? Bravo

Define stock unopened motor please.
Back in the late 90's i went 11.1 bone stock motor except for valve springs. 10.80's @124-126mph with ported heads.
With the same motor in 2000-2001with ported heads/intake and a cam i went 134mph+ (stock pistons/rods/main caps/crank/main bolts etc).

 

[laz]

Define stock unopened motor please. The way it came from the dealer no cam intake porting head porting only mod is valve springs . The car we went 10.69 went 950s with a roller cam and ported champion iron heads no girdle caps all stock parts .

Unopened means just that, can't be much clearer. Pull the heads, it's been opened. Pull the intake or front cover, it's been opened.
