There is little in life more satisfying than removing a 948 manifold and exhaust system in favor of a relatively massive header and larger center exhaust pipe. Breathing is good. And even if this improvement adds just 3 or 4 horsepower to your little 948 engine, it just feels so good to do this, you may want to give it a try.
In the case of the photos below, you can see the 948 engine in our Bugeye “Mikki,” which we are upgrading before it departs for a new life in Ohio with new a new dad (Rob).
Above is the stock set up. You can see the tiny original exhaust pipe mated to the manifold. That joint between the two is a chronic problem (always leaking) and this is another benefit of fitting the header you see below. You can also see how much more gracefully the gases will flow out of your engine once the header is fit as shown below.
This car is also got larger HS2 new carbs as part of the package of upgrades we’ll do to this car before it leaves our shop. This is an awesome upgrade, as the new carbs are not worn out like most SUs out there in the world, and they are also larger than the stock H1s. So here we will put more fuel in, and more gas out. We cap that off with K&N air filters, so that all this breathing happens unobstructed.
This is our Spridget sculpture of the week!
