Are you running drop motor mounts?

[curtis]

i am useing convertable motor mounts

[BLOWNBY]

I had to use HP drop solid motor mounts $90. Lowers motor 3/4 inch. Perfect clearance. And I also have 4 in cowl
When you get that bad boy dynoed, give me your details. Also what is your setup. and what pullies.

I have a RR 2.7 for the YSI if your interested, I'm going to the 2.5" The 3" Vortech pulley only gave me 16 psi and would slip a little at 6,000 RPM. The 2.7 held better at even higher RPM's plus mor elike 20psi. I want to switch to the 2.5" for more low end and keep my shift point at 6200 RPM. Not looking for more top end power per say. But it's always good.

...I AM GOING TO HAVE MY CAR TUNED AND DYNOED TOMORROW...WILL I HAVE TO HAVE A CHIP BURNED FOR IT ALSO? I HAVE A 393 STROKER WITH 10 TO 1 COMPRESSION...I DONT KNOW IF THE 3 INCH BLOWER PULLEY AND THE 8 INCH CRANK PULLEY IS THE RIGHT BOOST FOR THE 393 EFI...DO YOU KNOW HOW MUCH THE 3 AND 8 INCH PULLEYS PUT OUT? WILL IT BE TO MUCH BOOST FOR MY 10 TO 1 COMPRESSION....THANKS FOR YOUR HELP....CURTIS

I can't say what the boost will be but i wouldn't go to the dyno without some 112 in the tank!

10:1 is pretty steep for a blower. With the 8 & 3" pullies I made 16 psi at 6,000 RPM. I have no idea as to what you'll make with that compression. If you could get you compression down around 8.5 or 9 to 1 you should be making in excess of 700 RWHP.

[RSNovi]

I run a 10 - 10.5 compression 306 with 18 psi on 100 - 104 octane and have had very few problems.

Give me some info on the car. Also Sriver or pass. side. What type of numbers did you make. What is your timing and do you have the msd BTM?

Thanks

It is a typical NMRA Real Street car. TFS TW heads unported, TFS street heat intake, stock cam, and passenger side Novi 2000. It makes around 560 rwhp. I use an Autologic chip with approximately 27/28 degrees under full boost.

.....i have 42 lb injectors in my 393 stroker engine...how much hp are the 42 lbs good for? thanks, curtis

[RSNovi]

I switched to 55#. 42's didn't support 550+ rwhp.

[BLOWNBY]

My 42's worked with an FMU with about 520 rwhp. I now have 60's

What tranny? If Auto stall coverter? What do your sixty foots look like. Also what size rear slick and gear.

Thanks

Good point, I didn't specify that I was not running an FMU.
