Let's look at it like this. Which looks as if it flows well? Which does not?

This is NOT a comparison with Inline Pro's manifold or with the Lovefab Mini-me, but with all of the weldbend log manifolds instead.

Typical Log Manifold




Tubular Manifold

Well put Timg.

Again, we have dyno'd more than JUST our cars and brian has tuned more than just a few hondas, so we've seen many different turbo setups vs many different engines.

There are many comparisons from a log vs tubular but our manifold was not used. Even though our manifold looks like a "typical log" there was a design to it that allows it to work so as well as it does.

I have yet to see a crack in my InlinePRO manifold.

until the day comes when someone on the same day switches manifolds on their own car from log to tubular, and makes more power, i won't believe the hype.

2qyk4u, what kind of manifold are you running now??? If you are running a inline pro manifold i highly doubt full race will make 60 more hp than that with same boost levels and all

2QYK4U, just look at numbers at the same boost levels as you i cranked out 375whp. Exact same set up except the turbo. The turbo size makes a big difference

I have an inlinePRO turbo manifold. Full-Race knows this, and will guarantee me that their turbo manifold will make at least 60rwhp. Here is a direct quote from them:

"We will guarantee those gains only if you used an approved tuner, do a baseline test, change only the manifold downpipe and wastegate, and retune on the same dyno within a reasonable amount of time. This may seem like a lot to ask but we are very confident in our products and we have done a lot of back to back testing and this is the most reliable method. As long as you follow this guideline we will guarantee a 60 -70 hp gain."

I understand that a larger turbo is capable of making more peak power, but it also takes longer to spool. I specifically chose a GT30R over a GT35R because I plan to road race my car and the GT30R spools quicker.

around what RPM are you making full boost at?

as an example. LoveFab GT1 the vtec is set @ 4500 but with inlinepro Vtec is @ 6500.

wouldnt this lead to a much meatier midrange powerband for the lovefab even if the peak HP is the same?


(i know there is more to it than that but just using this as a rough example)

with my inline pro turbo i have vtec set at 5500, also, when your boosting and making power, if you can feel vtec over boost, then somethings wrong, i havn't felt vtec since my car was stock.
