Dyno Comparison For Each Part Added

Dyno Comparison For Each Part Added
We have a customer that is the original owner of a completely stock 95 MB PEP. He brought the car to us to sort out a few things earlier this year, major issue being the OE cardboard LIM gasket was blown, producing crappy idle and no power since it was a huge boost leak.
Fixed all the gasket with the new OE metal version and installed an ACT HD SS clutch, Koyo radiator, AST and installed an HKS downpipe. All power restored plus a few extra.
Our customer decided that it was time for some more power and better handling, so I decided it would be a great opportunity to document the HP gains (or not) of common bolt on modifications.
Unfortunately I did not dyno the car with the stock precat, slipping clutch and boost leaks.
As the car sits with the current mods, really only the HKS downpipe as far as HP adders the car made 254rwhp/222tq

The car is currently here for Apexi catback, Apexi intake, SMIC, PFC and HKS Twin Power. Along with some HKS coilovers.
I will install the catback and throw it on the dyno to see how it compares to the stock catback. Then install the Intake, then the PFC, then the SMIC or HKS TP. Stay tuned.

I've been fortunate enough over the years to both drive and own quite a few low-mile stock original engine original twin turbo cars and they always ran surprisingly strong, if taken care of and not tinkered with. As Mazda built these cars back in the early to mid 90's they did run very strong with a great power band, although man a stock car is quiet
Glad to see you doing this Chris, will be interesting to see some results

Just did a pull with the Apexi N1 Dual installed, keep in mind this still has a stock main cat and stock ECU, I can do no tuning at all at this point. Results were still impressive. Here is the dyno run and a comparison overlay of HKS downpipe only. Car made 264rwhp/241tq so it picked up 14hp & 19 tq, more importantly the increases were across the entire rpm range. There was a small increase in boost after transition, but overall the boost remained the same. It also completely eliminated the dip in HP at 5500rpm that was evident on both the HKS DP only dyno sheets.

Apexi intake installed and the results were also impressive. The car made 276rwhp/254tq, so it picked up 8hp/13tq, more importantly again it was through the entire rpm range and not just peak power. We will be able to address the small spike tomorrow, when the PFC is installed and I will be able to actually start tuning the car. I will show the differences in power from the stock PFC map and a map that is tuned specifically for the car. The peak torque reading will actually be lower, since the spike after transition is providing peak reading that is not consistent with the overall. Eliminate the spike and the peak torque will be closer to 225
