I finally got the bugs worked out of my Fogger Nitrous System. We put down a 7.10 @98 this weekend and got sideways in second and had to pedal it. This car might have a 6.9X pass in itt but the air was perfect this weekend so maybe not. Had lots of fun this weekend with full exhaust and ran with most of the race cars on the track.

[outrgus]

nice work

 

[allenman85]

Good job! What was the problem? Solenoid?

You going to Rusk on the 23rd?

 

[slow-poke]

Did you get any air under those skinnies?

 

[Thordane65]

Wow... good job!
Car looks awesome too... and ya, looks like there is daylight under those fronts!

 

[GregP]

Nice times, Curtis!

[fender2k5]

Looks great man..... what motor do you have in there...and what suspension do you have on the back

 

[cahorne]

allenman: The plunger in the nitrous solenoid was bad. I replaced it with a teflon plunger and the problem was gone. I could not tell any physical difference in the appearance though???

The wheels are coming off the ground in the front

The engine specs are listed in "my cars"

Definetely going to RUSK on the 23rd.

Greg, When will your car be ready?? Do you know where I can find a 9" housing. I have a third member, trac lock and gears but would like to build another rear end up for the 67 stang I just bought.

 

[Vinyl66]

Awesome times! Great looking car too.
There has to be some daylight under that driver side tire.
I can only hope my 347 runs near to what yours is running.
Give us some suspension specifics. Traction bars? Springs?
Tires? 1.5x 60 foots sure would be fun!

 

[tonys10sec306]

good times!!

 

[289nate]

Very nice! What was the 60 ft.? What suspension and tires are you running?

 

[Freddie]

Great times, they come out to 10.90's in the quarter mile !!

 

[cahorne]

Thanks for the kind words.

The two nitrous runs that night were 7.10 with a 1.60 60 foot and 7.13 with a 1.59. launching at 4K.

The suspension is a 5 leaf, rancho shocks set at 7 and shelby under ride bars welded to the sub frame rails and the rear u bolt plates. I run MT 26X8.5 slicks. I was hoping the car would get into the 10's but I think reallistically it will probably run in the low 11's. I am going to a 1/4 mile track in early June and we will see then, of course it will probably be 95 and 70% humidity

I re-cammed this motor last year and switched from the high rise single plane intake to the dual plane Air Gap and a 1" wilson manifold spacer and the car responded well. The new cam was smaller with 555 lift and 238 duration compared to the 565 and 242, but the ramp profile was better suited for the engine. If I had to do it over again I would probably run 11.0 compression as I think the heads cold easily disperse this kind of compression on pump gas without detonation. I was also surprised that this engine makes max power under the curve at a conservative 33 deg timing. If this car was an automatic and a little lighter it would be a monster but my objective was for it to remain a street car, thats why I still have AC/heater and full interior. My compromise to racing is the roll bar, but it has swing out shoulder bars so I can get in the car easily and I have a family to support so safety is a priority.

I can only compare this engine to the 289's and 306's, but the 347 really is a torque monster for a small block. The dyno runs we made showed my max torque was higher than the HP numbers on both motor only and nitrous pulls. While rolling along at 20-30 mph in 2nd the tires will go up in smoke quite easily. Makes for a fun street car, but you definitely need to be pointed straight.

Sorry for the long post....

Glad to see you got that thing worked out. Looks like you are running good. Now you and I can run a close heads up race your spray to my motor

 

[Thordane65]

Thats awesome.... nice car.
Ya, its tough to balance race and street...a lot of us here are in the same position. Nice to hear that the roll bar with swingouts works well... thats my next year upgrade. Did you use Chris Alston chassis?
Anyway, nice ride and lets hear how the 1/4 times are when you go!
I run the same rear set up as you and have a best 1.68 60-foot... still some traction issues to work out. Im shooting for mid 11's with the new solid cam.

 

[FasterDamnit!]

What are you rwhp numbers on the motor? Very nice 1/8 mile for not running all out.

I am putting together a 347, ported Twisted wedges, 232/240 Comp Cam's XE for my '65. Have a cleaned up Vic Jr intake to start. Just threw on some Cal-Tracs and an almost finished with the front disc brake swap. I am hoping it will squeek 10's on the motor.

 

[GregP]

Curtis,

Let me look around for a housing. They are getting scarce around here, but I'll check the junk heap at the shop.

I presume housing width is not an issue, right?

Here is the dyno post on the motor and nitrous:

http://www.fordmuscle.com/forums/dyno-techboard/my-66-stang-w347-now-with-video_47868.html

Getting into the 10's on motor is quite a challenge. I have a few other buddies and they are running 11.20's and an occassional 11.0X but the 10 is very difficult unless the weight is really stripped out. The main problem with my engine is the 2.05 valves. I really think these engines want 2.02 so they can get port velocity. My car weight 3200 with me in it. The other 66 weighs 3100. I think you will have to get the car to 3000 or less and put down 450 to the ground with an automatic. A four or five speed car will need 475-490 to the ground. These numbers put you at close to 600 flywheel which as you probably know begins to challenge the stock block. You will also probably need an electric water pump. Good Luck.

 

[cahorne]

GregP. Any 9" would probably work. Thats why they make chop saws and welders right!!!!!

 

[FasterDamnit!]

I beg to differ on the rwhp needed to hit 10's at 3000lbs. (My '65 last weighed in at 2940 w/ 1/2 tank and spare still in it). Did you see this?

http://www.fordmuscle.com/archives/2005/02/YellowFever/

I have watched four different mustangs hit hi 10's at Sacramento with 390 to 430 rwhp numbers (dynojet for the higher numbers, Mustang dyno for the lower). Weights were 2900 to 3200. All hooked in the lo 1.5's w/ Drew's car hittin 1.4's.
