New 305 is in and tuned! The first pulley results are in....

598 RWHP, 604 FT LBS TRQ @ 16 Lbs of Boost. Max power acheived at 5800 rpm.

So the ole Vortech V7-Ysi is finally kicking out some good numbers.

Have the drag racing pulley still on order but should se 25 lbs with that one. Trying the Gates Poley Gog Carbon GT belts system and very happy so far.

 

Wow that is some great power!
The TQ is killer as well. What does your set up include if you don't mind disclosing Once again though very nice.

 

Damn thats some nice power out of a 305..

 

Factory 305 block, over .060 with JE flat top pistons, Eagle H-Beam rods, Eagle forged crankshaft and Eagle four bolt splay conversion. Running a Rattler balance and Centerline SFI steel flywheel with their new puck style disk and pressure plate. The heads are Edlebrock Performer heads for center bolt valve covers. Running 1:6 ration Crane roller rockers and Crane HP replacement OE roller lifters. The cam shaft is an old school adaptation so I could run a Crane belt drive system. The injectors are eight Accel low impedance 45 lbs and two Accel high impedance 150 lbs injectors running on a piggy back FIC. The intake is a Holley twin 58mm throttle body into a stock upper to SLP runners into a stock base, all VERY ported for flow and matching. I’m sure I missed some detail, so please feel free to ask.

Yes, I’m still running the “beefed” up 10-bolt…. I know that makes to 10 bolt haters disappointed, but as my post explained from last year, IT WORKS! My gross horse power is over 700 and I’ve taken the car to a couple events so far. The miracle is the T-5 with no modifications still hanging in there!? Though by now I would have to send it off to World but that day hasn’t come yet.

The question on AFR is we maintained 11.8:1 and the timing is set OE due to still running a factory ECM and factory chip. The timing master kicks in at 6 lbs and subtracts one degree of timing for one pound of boost. This is conservative because we never had detonation indications on all the pulls made.

Gates has developed a belt system (Same as on Top Fuel Dragsters & Funny Cars) called a Poly Cog Carbon GT (think I wrote that right). It is a polyurethane belt with a carbon fiber carcass. It is ultra strong and has much less drag than a conventional rubber belt. ASP builds the pulleys for this system. You can not run this belt on a standard cog pulley, so don’t try. The pitch is slightly different. Another nice feature of the belt is it won’t suffer stretching.

Sorry about any typo….Thanks for all the great questions.

PS- The last pulley should make right at 700 RWHP. I’ll write in with the results next month.

 

Put some slicks on it and take it to the track and I bet it wont. Not trying to rain on your parade there but that power WILL break your 10 bolt in time and no,that T-5 wont survive either.

I checked out your page in your sig and your car is VERY clean...keep it up!

 

That is totally badass!!!

 

Thats sweet..... i got to find that thread on the bullet proof 10 bolt now
