hp/tq/ and 1/4 with a 76mm/78mm turbo

[c0ncEpT]

Martian knows what hes talking about for sure. I'm starting to like the smaller cams. More torque down low to help the car accelerate early in the run.

[Formula Z]

Yep he mentioned that. Full power at a lower rpm as well. Think rpms are what killed my last two engines

[hoogiesngrinderz]

Just one he specd for my setup.

223/231 .598 .617 112 +6

I think thats right

Thats for a stock 5.3 w stock heads, 76mm, ls6 intake, 4L80e w 3400 stall

I'm intrigued. +6 isn't what I expected

[Formula Z]

I dont even understand what the +6 means. Been trying to google it. I trust martin. Cant find a single bad post about him

Just ordered a custom grind boost cam from martin @ tick performance. This guy knows his stuff. Ordered a few other things over the weekend. Its time to start getting this project moving. Gonna be a long winter but for some reason I feel like im gonna be stressing getting stuff done before spring lol

Good deal! Should have went through me and I could have saved you some money a we talked about!

[Superman09]

Have you decided on a turbo yet?

[Formula Z]

Have you decided on a turbo yet?

Not exactly but I will be going through you on it. One of the last things im gonna worry about though.

[Formula Z]

Whats the benefits of going with the t7875 vs the tc78? I could see if I had an engine built for boost, but my stock 5.3 will it make that big a difference?

[Nocooler]

the tc78 has a 68mm exhaust wheel and the 7875 has a 75mm exhaust wheel.

The bigger wheel will have less backpressure

Which turbo did Martin spec the cam for?

[Formula Z]

Just a 76mm, no specifics. Maybe ill email him and see

[Formula Z]

We talked about everything except a specific turbo. I just said a turbonetics 76mm. Guess it will make a difference. Better start saving my pennies

[c0ncEpT]

The +6 is advance ground into the cam. It moves the intake centerline.

I would spend the money on the 75mm turbine. Its just a better turbo all around for pretty much any V8 application. Your going to make more power with it and not lose any spool time over the 68mm IMO.

[Superman09]

If you ever want to make power down the road, more than 600 rwhp, the 7875 is definitely wise to purchase now. Will save you money and time having to swap later on. The TC78 will work great now up to about 600 rwhp, however the 7875 will do the same and do it at less boost as well along with giving you more room to grow!

[Formula Z]

Guess its the 7875! Got a bit to do before then but at least we know. Car will be done by spring no mattet what

If the 7875 was available when I bought my turbo I would have likely went that route. If you are looking to save money, On3 is supposed to release a 7875 around Christmas time. Jonny, have you heard anything about the on3 7875? Think you might be able to source them?
