I havent posted in FI in a LONG time, so I thought Id make a re-appearance. This is my personal car, will be back up and running within a week. Apparently when you downshift to early, the engine over-revs, causing retainers to snap like toothpicks
I caught it in-time so no engine destruction, but the head is in the machine shop being serviced, for a return hopefully by this weekend.
Here is the setup:
GT4088R turbo;
LoveFab Sidewinder-GT1;
4" downpipe, exhaust;
Precision 1000cc injectors;
AEM 1052 EMS;
AEM UEGO;
Precision 750hp core(contemplating V-mount still, depends on time-issues);
Stock block;
Cometic 2mm headgasket;
Supertech springs/ti retainers.
I plan on revving to 9500rpm, 14psi on pump gas; should be deep into the 400whp range, might tag 500whp
Pictures(some are old, as new parts arrive, new pictures will be up):








4" DP shots:







Just thought Id start the thread now, as the car will be coming together within the next few weeks. With dyno numbers, complete pictures etc; I miss long build-as-I-go threads

7psi it made 307whp/188wtq....ah here it is, WITH the bad head(drove the car for two months after my last track day, Im sure cylinder pressures werent great with retainers dropping the valves 3mm).

This was with the exact setup, as pictured in the first pictures, GT30/71R turbo.
Engine has 38,500 miles thus far, 15,000 of which were boosted HARD(and tracked even harder
).

Pretty much!
Borrowing a customer's manifold for a picture or three
My downpipe though

I would of thought you guys would started to place the waste gate so it is heading more inline with the flow of the exhaust gas?. Downpipe hit the manifold at all?
Nice work

the downpipe does rest againts the manifold in these pics, as the 40R places the downpipe slightly differently than the more "standard" turbos
But no, they dont.
There are major vehicular items in the way that prevent a perfect WG priority design, but the datalogs show that boost control is PERFECT thus far...

how's the rear diff holding up? i saw some people with big hp S2K's replacing the rear diff's with stouter units
either way that's sick, makes me want to get an S2K and start a new project
