    WTB: Turbo Blanket

    Re: WTB: Turbo Blanket PTP sells T3 (small) and T3/T4 (medium) blankets. So the T3/T4 will fit a SyTy? Or should I get a T3?

    Stock Turbo Bolt Pattern

    What's the bolt pattern of a stock turbo where it mounts to the downpipe? I'm missing one of the nuts and need to know what size I should shop for.

    Good exhaust system?

    What's a good exhaust system for a nice rumble from SyTys? My S10 has SyTy manifolds, turbo and downpipe -- but I want to make it sound better. Currently I've got a Dynomax Super Turbo catback (with stock cat) and it doesn't sound too much different than stock. Would a cat change make a...

    Air Intake Crossover Tube

    The black air intake crossover tube on SyTys, is that for bringing in air from the air filter across to the turbo? Do you think it can hold in boost if I were to use one for sending the boosted air across the fan to the driver's side to an intercooler? (This is not in a SyTy truck...)

    Hayden Electric Fan Switch

    Hayden Automotive 3647 http://www.summitracing.com/parts/HDA-3647/ * Fan Quantity: Dual The specs for this relay say its for dual fans, but the diagram in its instructions don't specifically show 2 fans. Do I assume I can wire up both of my (LT1) e-fans through this unit? Or if my fans have 2...

    Stock fuel pressure and injector size?

    Ok, I need some education on fuel pressure/injectors for SyTys. What is the size of the stock injectors? What is the stock baseline fuel pressure? And, baseline fuel pressure, is that measured at idle with vacuum? I don't have a SyTy, but I'm using SyTy injectors, so I'm trying to get a gauge...

    Stock Fuel Injector Specs for Tuning

    Re: Stock Fuel Injector Specs for Tuning FYI Bosch 280150756 are proprietary injectors they made for Ford so Bosch won't disclose a spec sheet. I suppose I could ask Ford to see if they will provide specs for their E9SE 9F593 B1B injectors. I think they came in Thunderbird SuperCoupes.

    Stock Fuel Injector Specs for Tuning

    Re: Stock Fuel Injector Specs for Tuning The majority of the specs online said 32# @ 45psi, so assuming that was accurate I went with 36# since my rail pressure is 58psi. After adjusting the Offset Table until my idle AFR was 14.5-14.7, I ended up with these values in my table (80% higher than...

    Stock Fuel Injector Specs for Tuning

    Re: Stock Fuel Injector Specs for Tuning Between VE, Inj Offset and Inj Constant, that constant seems to be the only variable that I know. Would there be any logic behind entering the flow rate and using the open loop tuning to adjust the Offset table until the AFR is ok? Rochester 15637677...

    Stock Fuel Injector Specs for Tuning

    Re: Stock Fuel Injector Specs for Tuning Stock PCM in my '99 S10. Marine MPFI intake with Syclone injectors. It drives great, the only real issue is a bog right off of idle. When I turn down the injector constant until the bog is gone, its too rich. So I think I need to setup the injectors...
