Sorry for the delay in getting back and answering questions. This was E85. The FP Black is basically an HTA3582 wheel shoe horned into a stock appearing housing. I didnt post it but the car made 370 on 92 octane pretty easily but it was focusing on the E85 tune so I didnt push the gas too...

Forgot to mention that, it is an FP race manifold.

I am impressed with the DSM version of the FP Black so far as it compares to my experience with the Evo 4-9 version. Here is a car that is pretty much mod for mod and boost for boost (where it matters) above 6400. The reason it was higher boost down low but the same torque is do to me using...

We have been taking care of Willy's GVR4 for quite awhile. It has been a stock 6 bolt for a long time, happy and content on 92 and a stock motor. However recently Willy got the power bug and decided to have us build him something that was capable of pushing the FP Black safely to 500whp...

Can't spell disappointment without DSM.Did this shop build the shortblock originally? From what I am reading I only see that they had the head of which isnt related to the failure. What were the clearances on the motor if you happen to know? There is always an explanation on what happened...

Fuel is the main component that affects how you tune. Next is oiling, making sure you run a half quart high prevents starvation in corners. What we find with the Evos is pretty simple-Gasoline- 2* lower timing than a normal drag tune, 10.7-10.9 AFR, 21-22psi. Intercooler efficiency as well...

That was also on a junkyard, 20+ year old trans, that only had valvebody and clutch packs. A new trans like Jeff's with cryo'd internals is already underway...as are some other mods.

They will definitely leave room to grow with a bigger turbo or different intake manifold.

yeah those would be fine.

I apologise, I thought it was fairly concise in context.Any equivalent GSC camshaft, i.e. Kelford 264s to S1s, 272s to S2s, 280/276 to S3s in a Mitsubishi 4G63/4. Personally invested, no. I use them and sell them because they have been proven at the track with real times and on the dyno...

Kelfords are knock happy and consistently make 20whp less than any GSC product. Like I said, fixed. But what do we know, we just helped test all of the designs for the last 6 years?

fixed that for youNick

You really shouldnt be running the HKS with stock springs. I know they are advertised that way but any DSM with unknown mileage stockers needs new valvesprings.

Kelfords consistently make 20whp less, need degreed, and are more knock prone. If wanted that I would leave stock cams in my DSM.Short answer- GSC>Kelford

There will always be a little loss with more duration. As was pointed out though the S1s dont lose anywhere. In the Evos we use those as Roadrace and rally cams. I dont know where you are seeing full boost at right now, but typically an HTA3076 and 2.0L with S2s will spool just before 4,000...
