Toyota MR2 Message Board - View Single Post - New intake manifold option presented by ATS

1fastsol · 04-09-2008, 03:45 PM

We just finished a back to back test on a customers car using the ATS Center feed 65mm Throttle body manifold. To make the results a comparable as possible we put Kyle’s car on our dyno and did a few base pulls @ 17 psi with the stock (extrude honed). Then without removing the car from the dyno I installed the ATS manifold I built the week before. What we found was exactly what I expected around a 25 HP gain across the board at the same boost level (17psi). After installing the ATS manifold we soon found out that Kyle’s car had a extrude honed factory manifold so we might have seen even more gains if his car would have had a completely stock manifold to begin with. Also looking at the Autronic logs we made the ATS manifold actually spooled 200 rpm sooner than the stock unit. :smile:

Here is the back to back comparison. 17 psi The 371hp was the most it made on the stock manifold it did many 363-365 hp pulls so I thought I would post the highest of the stock manifold.

Mods on the test car

ATS 2.2l stroker
TTE head gasket
Built head
HKS 264 cams
ATS gt3082 turbo kit
RX7 850cc injectors
ATS intake manifold
Wilson 65mm Throttle body
ATS phenolic spacer
Butterfly exhaust
Custom trunk mount intercooler built by ATS
Synapse bov
Autronic tuned by ATSScott
The list goes on

Here is a pull at 25 psi that was cut short do to a lean situation caused by a lazy supra fuel pump. You can see where this was headed

I never did a back to back race gas run but the previous best @ 25 psi was 444 HP.
