But as petrolheads, gearheads, car guys, whatever you call yourself, we need to upgrade our vehicles for faster track times, better driver feel and are always in the pursuit of more power. Katech is ready to help us out there with their Street Attack and Track Attack packages for the 2015 C7 Corvette.
Best of all? You get to keep the naturally aspirated LT1 V8. As if that didn’t your attention, if you missed the headline, these two packages offer 650 hp without forced induction. That figure is achieved through the following performance upgrades, as provided from Katech:
- 427ci Street Attack LT1 engine
- Forged 4340 crankshaft
- Forged H-beam rods
- Forged 2618 pistons
- Halltech C7 carbon fiber air intake system
- Katech Camshaft
- VVT limiter
- Katech AFM delete billet valley cover
- High speed lifters
- High Lift valve springs
- Valve spring locators
- Intake valve seals
- Exhaust valve seals
- Titanium valve spring retainers
- C5-R timing chain
- LT1 long stroke piston squirters
- Katech CNC-ported heads
- Chassis dyno calibration
Apparently, it’s quite a bit of work to achieve those numbers without forced induction, but the fact Katech is up for the challenge delights us. There is one hiccup, though. Studying the offerings shows availability for the Street Attack package for February 2014. As you know, we’re living in 2015. Hopefully this is a typo, and Katech hasn’t gotten our hopes up for no reason.
Would you rather the forced-induced power from the LT4 supercharged small block V8, or would you prefer the naturally aspirated route with the Katech upgrade listed? Let us know down below what you’d prefer.
